Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

Houston startup founders take one-of-a-kind projection device into manufacturing phase

splay saves the day

A Houston company born out of Rice University has crowdfunded its way into the manufacturing phase of its startup journey.

Arovia, founded by Alex Wesley and George Zhu, has a product that solves some major obstacles people on the go face as they work — or entertain — from home, a hotel, coffee shop, etc. Splay is a unique collapsable, portable device that doubles as both a display and projector.

The founders first launched their product in 2016 and raised over $700,000 from backers on their crowdfunding campaign. After raising investment funding, including an investment from the Texas Halo Fund, Wesley and Zhu recently returned to their crowdfunding roots and ran a 30-day pre-order campaign on Kickstarter during which they sold over $300,000 worth of product.

“We couldn't have made Splay without the Houston Startup Community," Wesley says.

Wesley was an MBA student when he met Zhu, who was working towards a B.S. in Mechanical Engineering, after posting a job description in search of a co-founder, a requirement of the Owlspark program.

“Owlspark accepted the business idea, with the stipulation that I needed to find a co-founder,” says Wesley. “I sent out a job description, and a big part of the application process was to provide ideas for making this crazy idea work. I sent the job description at around 9 pm and received an email from George at around 1 am with an extremely detailed proposal. That was the start; and since then, we’ve basically been like brothers — I’ve even lived with him and his parents in China.”

Wesley credits Owlspark as an important part of their formation, beyond the impetus for their partnership.

“It was a great experience for us. The focus on customer interviews is something that is very easy to avoid, but it’s extremely important. You don’t have a product if nobody wants to buy it — you don’t have a company without customers," Wesley says. "During our time at Owlspark, we did over 100 customer interviews, which gave a lot of insight into the viability of the idea and who it would be useful for. We still utilize many of those insights today.”

But Owlspark wasn’t the only accelerator program that Wesley and Zhu joined. They also participated in Hax, a top hardware-focused accelerator, and Luminate, a top optics-focused accelerator. They also competed in the Rice Business Plan Competition, which Wesley says helped them refine their pitch which ultimately secured their funding.

“We pitched at angel groups including the Houston Angel Network and their fund The Halo Fund, Keiretsu Forum and their fund Keiretsu Capital, Rochester Angel Network, and the GOOSE Society. We also won the Texas A&M New Venture Competition,” says Wesley.

With this financial backing, Arovia received the necessary support for the R&D phase for Splay, taking the product into its manufacturing process and pre-sale campaign.

“Yes, it went very well,” shares Wesley, adding that they are still looking for support on the Indiegogo campaign. “Now we are focusing on pre-selling in other markets, like Japan."

Splay can be used as a portable screen, or the projector can be removed to be used on its own. Photo via Splay

Houston has all the potential to lead the energy transition — it just needs to make sure it has all the right ingredients. According to John Chappell, a key ingredient is blockchain. He explains in a guest article for InnovationMap.

"Houston has earned its title as the Energy Transition Capital of the world, and now it has an opportunity to be a global leader of technology innovation when it comes to carbon emissions reporting," Chappell writes. "The oil and gas industry has set ambitious goals to reduce its carbon footprint, but the need for trustworthy emissions data to demonstrate progress is growing more apparent — and blockchain may hold the keys to enhanced transparency."

When venture capitalist and angel investing expert Kyra Doolan started navigating her own fertility journey, her eyes were opened to a huge market opportunity across femtech. As managing director at Houston-based Texas HALO Fund, she took these opportunities to her team of investors.

"A lot of the issues that face women, are things that are not talked about," she says on this week's episode of the Houston Innovators Podcast, referencing things like miscarriage, injury during childbirth, etc. "For a lot time, women just sat back if they had these issues, and they kept it to themselves, so those problems weren't being addressed."

Doolan says she and other women aren't taught how to manage their own fertility journey, but it doesn't have to be that way. Click here to read more.

Houston-based Empower Pharmacy has celebrated the grand opening of its new $55 million, 86,000-square-foot facility that includes extensive automation, a top-of-the line cleanroom, and equipment that generates purified water, clean steam, and clean compressed air. The space also features a warehouse capable of storing at least nine months of raw pharmaceutical ingredients to minimize supply chain problems.

"This innovative facility, combined with our more than 500 dedicated employees, enables us to increase our operational capacity, allowing us to prepare thousands of custom prescriptions each day for millions of patients across the country," Shaun Noorian, founder and CEO of Empower Pharmacy, says in a news release. "We are setting a new standard for compounded medicine, striving to achieve a superior pharmaceutical experience, from order placement to delivery."

The new Empower Pharmacy facility, at 7601 N. Sam Houston Parkway W., opened earlier this month. Click here to read more.

Houston investor shares why she's focused on funding the future of femtech

HOUSTON INNOVATORS PODCAST EPISODE 98

Successful investors find gaps in the marketplace and direct funds into startups and technologies resolving those gaps. For Kyra Doolan, managing director at Houston-based Texas HALO Fund, femtech represents a huge opportunity for innovation.

"A lot of the issues that face women, are things that are not talked about," she says on this week's episode of the Houston Innovators Podcast, referencing things like miscarriage, injury during childbirth, etc. "For a lot time, women just sat back if they had these issues, and they kept it to themselves, so those problems weren't being addressed."

While Texas HALO Fund has invested in femtech since its first fund in 2012, Doolan shares on the show how she personally saw an investment opportunity with kegg, a fertility tracking device. Doolan says she and other women aren't taught how to manage their own fertility journey, but it doesn't have to be that way.

"I was at a stage in my life where my eyes were open to the gaps that are out there and the conversations that weren't being had," she says. "In looking into Kegg, it showed me what the market was and how many gapes there were in the market just around fertility."

Texas HALO Fund has a few femtech companies in its portfolio now, and the most recent addition is Houston-based Work & Mother, a company that builds out fully-equipped nursing accommodations in office buildings.

Despite it's growing femtech portfolio, the fund is industry agnostic, though, Doolan says, about a third of the companies Texas HALO Fund invests in reside in the health tech space. What makes HALO different is its focus on early-stage startups.

"We like to get in early," Doolan says. "We're, what you would historically consider 'pre-VC,' but now that's getting a little bit blurred. ... We're some of the earlier capital that's invested, and we continue to make investment as the companies continue to subsequent rounds."

Doolan shares more on her passion for femtech, as well as her advice for founders looking for funding and potential female investors looking to get into investing on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston female-focused health tech pitch competition names big winners

winner, winner

From the comfort of their own homes, several female entrepreneurs accepted investment and pitch prizes at the finals of an inaugural awards program created by a Houston-based, woman-focused health organization.

Ahead of the Ignite Madness finals on Thursday, October 29, Houston-based Ignite Healthcare Network named nine finalists that then pitched for three investment prizes. The finalists included:

  • Eden Prairie, Minnesota-based Abilitech Medical — medical device company that creates assistive devices to aid those with upper-limb neuromuscular conditions or injuries.
  • New Orleans, Louisiana-based Chosen Diagnostics — a biotech company focusing on custom treatment. First, Chosen is focused on creating two novel biomarker diagnostic kits — one for gastrointestinal disease in premature infants.
  • San Francisco, California-based Ejenta — which uses NASA tech and artificial intelligence to enhance connected care.
  • Highland, Maryland-based Emergency Medical Innovation — a company focused on emergency medicine like Bleed Freeze, a novel device for more efficiently treating nosebleeds.
  • Columbia, Missouri-based Healium — an app to quickly reduce burnout, self-manage anxiety, and stress.
  • Farmington, Connecticut-based Nest Collaborative — digital lactation solutions and support.
  • Palo Alto, California-based Nyquist Data — a smart search engine to enable medical device companies to get FDA approvals faster.
  • New Orleans-Louisiana based Obatala Sciences — a biotech startup working with research institutions across the globe to advance tissue engineering and regenerative medicine.
  • Perth, Australia-based OncoRes — a company that's developing a technology to provide surgeons with real-time assessment of tissue microstructure.
The inaugural event that mixed health care and basketball — two vastly different industries with strong connections to women — attracted support from partners and sponsors, such as Intel, Accenture, Morgan Lewis, Houston Methodist, Johnson & Johnson Innovation, and more, according to Ayse McCracken, founder and board chair of Ignite.

"Our partners and sponsors are an integral part of our organization" says McCracken. "Without each and every one of them, the networks, resources, and commitment to advancing women leaders, we would not have grown so rapidly in just four years and our IGNITE Madness event would not enjoy this vibrant ecosystem that now surrounds female entrepreneurs."

First up in selecting their winner for their investment was Texas Halo Fund. Chosen Diagnostics took home the $50,000 investment.

"While we were impressed by everyone who pitched tonight, one company stood out to us," says Kyra Doolan, managing partner. "[Chosen Diagnostics] exemplifies what we are looking for: an innovative solution, a strong CEO, and a real addressable market."

The second monetary award was presented by Tom Luby, director of TMC Innovation. The award was an $100,000 investment from the TMC Venture Fund, as well as admission to TMCx. The recipient of the investment was OncoRes.

"We are absolutely blown away," says Katharine Giles, founder of Onco. "We've already got a great link to Texas and looking forward to more."

The largest monetary award that was on the table was presented by Wavemaker Three-Sixty Health, a leading Southern-California based, early stage venture capital firm, for $150,000. However, at the time of the announcement, Managing Partner Jay Goss decided to award four startups an undisclosed amount of investment. Goss says he and his team will meet with each company to establish an investment.
The companies that were recognized by Wavemaker were: Healium, Ejenta, Emergency Medical Innovation, and Nest Collaborative.
Lastly, Ignite itself had $27,500 cash awards to give out to the pitch competition winners. The funds will be distributed between the winners. OncoRes took first place, Abilitech came in second place, and Obatala Sciences took third place.

Houston researchers develop breakthrough device that could bypass spinal injuries

breakthrough research

Scientists at Houston Methodist have announced a significant leap forward for spinal cord injury recovery.

The researchers have developed a device that essentially bypasses spinal injuries, allowing signals from previously “lost” functions to reach the brain, a new study published in Nature Communications shows.

“Most current technologies try to improve whatever function remains after a spinal cord injury,” Dr. Damiano Barone, assistant professor of neurosurgery in the Department of Neurosurgery at Houston Methodist and co-lead on the study, said in a news release. “Our goal is different. Rather than fixing the injury itself, we want to bypass it completely and create an alternative route for signals to travel.”

The study involved a single ultrathin circumferential electrode array made to conform around the spinal cord without penetrating neural tissue, which was implanted into rodent and pig models with spinal injuries. The electrode array was able to interpret motor, sensory and autonomic signals around the injury. Think of it as a set of detours that restore road access to isolated towns after a disaster destroys the highway instead of just rebuilding the highway.

Over the course of three days, the arrays detected signals of intended movement from low-frequency spinal oscillations with more than 94 percent accuracy. This worked across species and was replicated in feasibility studies on human cadavers.

This research could serve as a new foundation for neuroprosthetic implants that could restore connectivity to the 2.5 million people worldwide suffering from spinal injuries that result in loss of ability. Future development could result in everything from restored organ function to mobility, according to Houston Methodist.

George Malliaras, the Prince Professor of Technology in the Department of Engineering at the University of Cambridge, who co-led the study, sees it as a fundamental restructuring of the science of spinal trauma.

“This could represent a paradigm change in how we think about spinal cord injuries,” Malliaras said. “Instead of starting from the idea that what is lost is gone forever, this approach asks whether we can restore function by carrying the signal around the injury.”

Further work involving laboratory models will need to be completed before launching human trials.

Grants from the National Institutes of Health, Houston Methodist Katz Investigator Award, Helaers Research Award and the Engineering and Physical Sciences Research Council helped support the study. Other collaborators on the study include Salim Hadwe, Ruben Serrano, George Psaltakis, Margaux Forner, Chaeyeon Lee, Sydney Swedick, Moleca Ghnnam, Tawfique Hasan and Alejandro Carnicer-Lombarte from the University of Cambridge; and Anton Banta and Xueer Zhang from Houston Methodist.

Abbott assembles expert team to help lure U.S. Space Academy to Texas

space race

State Rep. Greg Bonnen of Friendswood has been tapped to lead a new team that will promote Texas as the future home of the U.S. Space Academy.

Bonnen, a neurosurgeon, chairs Houston Physicians’ Hospital and the powerful Texas House Appropriations Committee. His House district is close to NASA’s Johnson Space Center.

Gov. Greg Abbott appointed the seven-member team. Last month, President Trump signed an executive order establishing the Presidential Commission on the U.S. Space Academy. Commission members, who held their first meeting this month, will recommend a permanent location for the academy.

Texas officials are pushing a site near Johnson Space Center to host the academy. Alabama, Colorado and Florida are among Texas’ competitors.

In a joint statement, U.S. Sen. Ted Cruz and U.S. Rep. Brian Babin, both of Texas, issued a statement backing the state’s bid for the academy. Cruz lives in Houston. Babbin lives in Woodville, about 55 miles south of Beaumont.

“America’s space program is built across the country, but Texas is where the pieces come together,” the lawmakers said. “We are ready to lead the next generation of space pioneers and look forward to showing why Texas is the right home for the U.S. Space Academy.”

The academy’s curriculum will include technical education, leadership development and public service components. Graduates will be set up for careers in the U.S. military, civil service, and aerospace sectors.

The Abbott-appointed team will work with the Texas Space Commission to prepare the state’s proposal for the academy.

In addition to Bonnen, team members with ties to Houston include:

  • Robert Ambrose, who grew up in Houston. He worked at Johnson Space Center before becoming associate director of the Texas A&M Space Institute.
  • Former NASA astronaut Nancy Curry-Gregg, director of the Texas A&M Space Institute. She earned a doctoral degree from the University of Houston and previously worked at Johnson Space Center.
  • Former NASA astronaut Jack Fischer, senior vice president of Houston-based Intuitive Machines. The company builds spacecraft, delivers payloads to the moon and launches satellites.

“Texas is the home of America’s human spaceflight program,” Abbott said in a release. “No state can match what Texas brings to this mission.”

“NASA’s Johnson Space Center, world-class universities, a premier commercial space industry, major military installations, and an unmatched aerospace workforce give Texas every asset the United States Space Academy requires,” the governor added.
