Tiny implant could revolutionize hearing and more Houston innovation news

Trending Topics

Editor's note: It's time to recap the top trending innovation news from the second half of April 2025. The most-read recent stories on InnovationMap include a revolutionary hearing aid device, space tech updates, a femtech company's rebrand and more. Get the details below.

1. Houston doctor aims to revolutionize hearing aid industry with tiny implant

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says. Continue reading.

2. Houston space tech startups share latest updates on lunar missions and more

Houston-based space tech companies Axiom Space and Intuitive Machines recently shared updates on innovative projects and missions, each set to launch by 2027.

Axiom Space, developer of the world’s first commercial space station and other space infrastructure, is gearing up to launch two orbital data center nodes to low-earth orbit by the end of 2025.

Meanwhile, Intuitive Machines, a space exploration, infrastructure and services company, has picked SpaceX’s Falcon 9 rocket to launch its fourth delivery mission to the moon. The launch will include two lunar data relay satellites for NASA. Continue reading.

The Liu Idea Lab for Innovation and Entrepreneurship (Lilie) has announced its 2025 Rice Innovation Fellows cohort, which includes students developing cutting-edge thermal management solutions for artificial intelligence, biomaterial cell therapy for treating lymphedema, and other innovative projects.

The program aims to support Rice Ph.D. students and postdocs in turning their research into real-world solutions and startups.

“Our fourth cohort of fellows spans multiple industries addressing the most pressing challenges of humanity,” Kyle Judah, Lilie’s executive director, said. “We see seven Innovation Fellows and their professors with the passion and a path to change the world.” Continue reading.

5. Houston femtech co. debuts first holistic wellness suite following rebrand

Houston-based femtech company Work&, previously Work&Mother, debuted new lactation suites and its first employee wellness space at MetroNational’s Memorial City Plazas this month.

The 1,457-square-foot Work& space features three lactation rooms and five wellness suites, the latter of which are intended to offer employees a private space and time for telehealth appointments, meditation, prayer, and other needs. The hybrid space, designed by Houston-based Inventure, represents Work&'s shift to offer an array of holistic health and wellness solutions to landlords for tenants.

Work& rebranded from Work&Mother earlier this year. The company was previously focused on outfitting commercial buildings with lactation accommodations for working parents, equipped with a hospital-grade pump, milk storage bags, sanitizing wipes, and other supplies. While Work& will still offer these services through its Work&Mother branch, the addition of its Work&Wellbeing arm allows the company to also "address the broader wellness needs of all employees."

Houston palliative care startup partners with new platform to expand reach

palliative care partnership

Houston-based Koda Health and Dallas’ Guidehealth, an AI-powered health care services platform, announced a strategic partnership to provide access to tech-enabled solutions to help improve care and reduce costs for patients navigating serious illness.

Health systems and clinically integrated networks working with Guidehealth can now deploy Koda Health’s Advance Care Planning (ACP) platform, which allows patients to document and share their care preferences, goals and advance directives for health systems. Guidehealth’s platform integrates into primary care workflows and allows providers to identify high-risk patients, coordinate care and reduce administrative burden.

Guidehealth also works with a team of virtual caregivers, known as Guidehealth Healthguides, who help patients navigate end-of-life decisions. With this new partnership, the Healthguides will be able to integrate Koda Health’s ACP platform into their workflows.

“Koda Health’s mission is to ensure that every patient’s voice is heard, especially during the most vulnerable times in their lives,” Dr. Desh Mohan, Chief Medical Officer and co-founder of Koda Health, said in a news release. “This partnership with Guidehealth accelerates our ability to reach patients at scale, especially those in value-based arrangements where care alignment and quality of life are top priorities.”

Guidehealth works with more than 500,000 patients and major systems, such as Emory Healthcare, according to the release. The company closed a $14 million seed round last year, which included investment from Memorial Hermann.

“Advance care planning is essential to delivering care that is not just high quality, but also compassionate and aligned with what matters most to each patient,” Dr. Sanjay Doddamani, founder and CEO of Guidehealth, said in a news release. “Koda Health brings a scalable, digital-first approach to a historically complex and emotional process. By embedding Koda into our value-based care ecosystem, we’re equipping providers to have meaningful conversations with patients, reduce unnecessary interventions and ultimately improve the experience for families and clinicians alike.”

Koda Health was born out of the TMC's Biodesign Fellowship and was launched by CEO Tatiana Fofanova, Dr. Desh Mohan, and Katelin Cherry in March 2020. It closed an oversubscribed seed round for an undisclosed amount last year, with investments from AARP, Memorial Hermann Health System and the Texas Medical Center Venture Fund. The company also added Kidney Action Planningto its suite of services in 2024.

4 trailblazing Houston innovators to know right now

Featured Innovators

Editor's note: Houston innovators are blazing new trails with medical breakthroughs and more. Here are four innovators to know, who have been featured on InnovationMap this month.

Dr. Ron Moses, creator of NanoEar

Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist is the creator of NanoEar, which he calls “the world’s smallest hearing aid.”

NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power — and a superior hearing experience — than the best behind-the-ear hearing aid.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. Today, NanoEar has nine active patents. The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding. Read more.

Dr. Fong Lam, Baylor College of Medicine, and Sergey Shevkoplyas, UH

A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said. “Our study is the first to solve this problem.” Read more.
