Houston company creates portable device that eases pain without the use of drugs

No pain, just gain

Many of the estimated 50 million Americans who suffer from chronic pain turn to drugs — including heavily abused opioids — to relieve their symptoms. Houston-based startup Portable Therapeutix LLC's drug-free solution to pain management seeks to put a dent in the market for prescription painkillers.

In 2018, Houston-based Portable Therapeutix introduced Squid Go, a portable device that's designed to ease the pain and swelling of sore joints and muscles. It's a follow-up to the company's Squid Compression, a pain management device launched in 2013 for patients at rehabilitation centers, hospitals, doctor's offices, and the like.

Squid Go enables consumers to apply two approaches — cold therapy and compression therapy — to relieving joint pain and swelling caused by arthritis, bouncing back from athletic activities, or recovering from an injury or surgery involving muscles and joints. Variations of the device can treat ankle, back, leg, knee, shoulder, or wrist pain.

To reap the benefits of Squid Go, a consumer uses the device for just 15 minutes. Squid Go — which combines a cold gel pack with proprietary compression technology — features special air pockets that inflate and deflate, gently massaging the body part needing treatment. That massaging boosts circulation and reduces swelling.

"Increased circulation brings more nutrient- and oxygen-rich blood to the area, promoting recovery," says Sam Stolbun, co-founder of Portable Therapeutix. "Meanwhile, [the] gentle compression also drives the pain-relieving cold from the gel pack deeper into the tissues to alleviate soreness and discomfort."

The coldness of the gel pack fights inflammation.

Stolbun says someone can take the lightweight, portable Squid Go device to the office, to the gym or anywhere else for on-the-go pain relief. It even can be used without the cold gel pack for compression-only therapy to improve circulation and decrease swelling. The Squid Go pump delivers about 15 treatments before it needs to be recharged.

Squid Compression received clearance from the U.S. Food and Drug Administration as a prescription-only device in 2013 and gained over-the-counter status in 2014. The consumer version, Squid Go, employs the same technology and operates the same way as Squid Compression, so a second FDA stamp of approval wasn't required.

Pricing for the heavy-duty Squid Compression system starts at $700. The consumer-friendly Squid Go system goes for $300 or $350, depending on its purpose. Users can buy extra wraps and gel packs to supplement the system.

Stolbun says he and co-founder Shai Schubert developed the Squid devices after realizing that existing pain-fighting cold packs provided only superficial relief, while water-based treatments were inconvenient and offered no compression advantages. Still other cold and compression therapies on the market are expensive and generally aren't covered by health insurance, he says.

Stolbun says that "it became apparent that a reasonably priced, well-made, portable, and effective pain relief and recovery device would meet a need for a broad range of consumers — from athletes to seniors."

Stolbun, a sports enthusiast and bakery mogul, and Schubert, a scientist and entrepreneur, established Portable Therapeutix in 2011.

The company's debut product, Squid Compression, still enjoys success, but Stolbun says the company has shifted its focus to Squid Go. Portable Therapeutix plans to pump up sales for Squid Go via its online presence, he says, as well as through physical therapists, sports trainers and other professionals who've used Squid Compression but want to offer the less pricey Squid Go model to their clients for in-home treatment.

Portable Therapeutix is backed by private investors; the amount of funding it has received isn't available. The company doesn't release revenue and profit figures.

Today, the company employs just one person in Houston but will add workers as its distribution pipeline expands, Stolbun says. Sales, marketing, and customer service representatives are scattered around the country. Stolbun, the CEO, is based in Houston, while Schubert, the chief technical officer, is based in Boston.

Portable Therapeutix relies, in part, on word-of-mouth praise to promote Squid Go. Among those hailing the device is Lee Ward of Houston, who describes himself as a competitive tennis player.

On the Squid Go website, Ward explains that he'd been suffering from progressively worsening tendonitis in his knees for a couple of years.

"I tried a number of remedies, including ice and gel packs, immediately following my tennis workout, but both remedies were ineffective and difficult to use," Ward says in his online testimonial.

He then discovered Squid Go and became a fan.

"The best thing about [Squid Go] is its ease of use. It provides a quick, effective treatment that makes it ideal for daily use by both the serious and recreational athlete," Ward says.
