In conversation with Souvik Paul, Founder of CathBuddy

What was the deciding moment in starting the company? Tell us about your vision.

CathBuddy’s origins traces back to August 15th, 2014. Carina, my girlfriend’s older sister, sustained a T2/T3 complete spinal cord injury in a car accident that took the life of her mother and left her step-father in a weeks-long coma. I spent the two weeks immediately following the accident in the hospital with my girlfriend, her family and Carina. That was my introduction to the world of spinal cord injury rehabilitation, adaptation, and catheterization.

At the time of Carina’s injury, I was transitioning from a career in finance to one in industrial design. I had to decide if I would pursue my plans for graduate design school. I knew that the entire two-year experience would be meaningless unless I could use my training to help Carina adapt to her new life.

I never wanted to be an entrepreneur, but I’m here because I believe in the product and the impact that it might have on the health and lives of people like Carina who use catheters every day.

While attending the School of Visual Arts in New York, I focused on design for spinal cord injury. I connected with over 40 people involved in SCI/D (spinal cord injury or spinal cord disorder) rehabilitation along the way – from people with SCI/D, physical therapists, occupational therapists, physicians, and case managers. Next, I worked at Johnson & Johnson as a design strategist and project manager with a focus on consumer medical devices. I continued developing the ideas generated in graduate school on the side. After incorporating CathBuddy, six months later I left Johnson & Johnson. It was time to focus on the new venture full-time.

Catheters were an important place of focus because of how psychologically important they are to someone who has recently sustained a spinal cord injury. Most people don’t remember when they were toilet-trained. When you’ve been in a traumatic accident, that trauma gets played back over and over when you find that you’re no longer in control of your body. Bodily functions you’ve taken for granted for as far back as you can remember, like urinating and defecating, are now outside of your control. The early days of rehabilitation are especially difficult – spontaneous discharge of urine and fecal matter are a reality. I wanted to make the process of catheterization easier. In many ways, I never wanted to be an entrepreneur, but I’m here because I believe in the product and the impact that it might have on the health and lives of people like Carina who use catheters every day.

Even when people use sterile single-use catheters, they have a 50% risk of sustaining a complicated UTI.

The company has evolved since its inception. We started off trying to make catheter reuse safer by developing a standalone catheter sterilizer. Carina was only covered for 110 catheters a month when she started using them, which required that she re-use her catheters. This re-use, we thought, was the reason that she was suffering from frequent UTIs. I surrounded myself with a team of experts, and we learned two things:

  1. regulatory bodies approved catheters for single-use only – approval of a device that explicitly allows people to reuse catheters would be a challenge; and
  2. even when people use sterile single-use catheters, they have a 50% risk of sustaining a complicated UTI.

That’s an absurdly high UTI risk for use of a medical device as directed. It suggested to us that there was an issue with catheter design.

Tell me about your customers? What do they need, and how are they challenged in their current situation?

With a physician partner on my team, we learned that no-touch catheter and closed catheter systems helped to reduce contact contamination of catheters. This contamination is believed to cause UTIs. No-touch and closed catheter systems are thought to reduce UTI incidence by 30% in clinical settings. The issue is that these catheters are often four times as expensive as standard catheters that insurers typically cover. The result? Not many people are covered for closed or no-touch catheter systems in Canada and the US.

Instead of developing a standalone catheter sterilizer, we designed a reusable catheter and insertion aid from the ground up.

The CathBuddy at-home sterilizer uses steam to completely sterilize up to six catheters and insertion aids between uses.

Recognizing that people sorely need not only a safe but affordable catheter, we pivoted our business model and product. Instead of developing a standalone catheter sterilizer, we designed a reusable catheter and insertion aid from the ground up. We incorporated reusability through the use of an at-home sterilizer as a way to make re-use as safe as it possibly can be for catheter users.

How are you providing a solution to your customer’s needs? Tell us how you are validating this through implementation and ongoing use.

We provide a two-part catheter system. Our catheter and insertion aid can be reused 100 times and is tagged with NFC. NFC, or Near Field Communication, allows the system to track how many times a catheter is used. The sterilizer’s firmware recognizes the placement into the sterilizer. This is a part of our quality control to avoid unsafe practices.

The catheter is reinforced so that it won’t crack over repeated use. The insertion aid provides best-in-class features commonly found in no-touch catheters that prevent contact contamination. It also simplifies the ergonomics of catheterization, and especially compared to products already on the market that require three hands to use effectively.

We designed the system with the consistent input of ten catheter users in a process that allowed us to constantly improve and iterate on the design to better meet their needs.

The second part of the system includes an at-home sterilizer that uses steam to completely sterilize up to six catheters and insertion aids between uses. It keeps track of how many times each catheter has been used so our customers don’t have to. We eventually want to incorporate an automated replenishment process for the catheters and insertion aids to take even more of the bladder management process off the minds of our users.

When users sign up for the system, they receive our at-home sterilizer and six catheters and insertion aids. This constitutes a three-month supply, and every three months they receive an additional six catheters. Users carry their six catheters and insertion aids with them for use throughout the day. At the end of each day, they disassemble and clean the catheters and insertion aids with cleaning tools that are included in the system. Afterwards, they reassemble the catheters, place them into the system, and start the sterilization cycle. The entire cleaning and loading process takes only five minutes to complete.

We designed the system with the consistent input of ten catheter users in a process that allowed us to constantly improve and iterate on the design to better meet their needs. We started by learning about their personal catheterization processes. Then we began testing concepts, sketches, 3D CAD models, and 3D printed models with these users.

What differentiates your company from the competition?

Our competitors are pretty firmly wedded to the single-use catheter model since it’s very profitable for them. We’re different.

We’re trying to find a way to challenge that status quo and pass on the savings of a reusable system to our end consumers. We have a strategic product development roadmap for products like smart catheters that simply aren’t feasible as single-use products.

Today, people are forced to choose between affordable catheters and safe catheters. Our system gives people access to catheters that are both affordable and safe, and that are easier to use than existing products because of the proprietary design of our catheter insertion aid.
