From the Ground Up:

Designing a Prosthetic That Works as Hard as You Do.

For upper-limb amputees, prosthetic devices can be life-changing tools—or sources of frustration. While the right prosthesis can restore independence and enable a fulfilling life, too many devices fail to meet users’ real-world needs, leading to high abandonment rates. According to a comprehensive review published in the Journal of Orthopaedics (Brack & Amalu, 2021), adult upper-limb amputees abandon their devices, with dissatisfaction stemming from issues like poor functionality, lack of durability, and discomfort.

At Marins Med, we believe that a prosthetic device should work as hard as its user. That’s why we developed the ProHensor, the only upper-limb device on the market featuring a self-actuated locking system that is serviceable in the field—an essential innovation for active users. Designed to empower amputees to tackle demanding tasks, the ProHensor will be classified as an FDA Class I device, ensuring safety and reliability.

Bridging the Gap Between Research and Real-World Needs

The Journal of Orthopaedicsarticle underscores a critical point: many prosthetic devices fall short because they’re not designed with the realities of daily life in mind. Devices often lack durability, precise motor control, or adaptability for hands-on work like construction, yard work, or mechanical tasks. For example, abandonment rates can reach 60% for shoulder disarticulation amputees, often due to inadequate training and high maintenance costs.

The ProHensor addresses these challenges head-on. Engineered with a user-centric focus, it’s built to handle the rigors of both hard work and play. Whether our CTO Darryl DuBre, a 34-year upper-limb amputee, is using the ProHensor to install hardware, repair equipment, or manage heavy-duty yard work, it proves itself as a reliable tool that adapts to a variety of demanding environments.

A Durable Solution for Active Users

Unlike other devices that prioritize aesthetics over practicality, the ProHensor focuses on what matters most: functionality and durability. The self-actuated locking system is a standout feature, allowing users to maintain a secure grip with minimal effort. And because the ProHensor is serviceable in the field, it ensures users won’t be sidelined by avoidable downtime—keeping them in the game, no matter the task.

This innovative approach aligns with the findings of Brack and Amalu (2021), who advocate for a greater focus on user satisfaction and device functionality to reduce abandonment rates. By delivering a prosthetic that meets the demands of real life, the ProHensor offers amputees the opportunity to reclaim their independence and achieve more than ever before.
