The ProHensor is indicated for upper-limb amputees who require a durable, body-powered terminal device for functional daily use. It is especially well-suited for users engaged in manual work or physical tasks, and for those who may have rejected previous devices due to fatigue or lack of fine control. The ProHensor offers enhanced proprioceptive feedback, allowing for intuitive grip modulation and improved functional outcomes.

The ProHensor features a user-actuated locking mechanism that allows the user to maintain a grip without continuous cable tension, unlike a standard voluntary-opening hook. This reduces user fatigue and improves control. The ProHensor is optimized for heavy-duty use and high-impact tasks, with grip performance rated to support up to 30 kg in lifting or sustained holding applications. It was developed with input from long-term amputee users and is designed for durability, field-serviceability, and confidence in demanding environments.

The ProHensor’s locking mechanism is activated through a voluntary-closing motion. Once the user engages the grip, the mechanism locks in place until released through a simple, intuitive movement. Patients often report that it feels natural and reduces the strain of constant shoulder or back engagement, improving day-long comfort and control.

Yes. The ProHensor is designed to integrate with standard wrist units, cables, and body-powered harness systems. It fits seamlessly into most existing configurations, allowing for straightforward fittings and adjustments.

Units can be ordered directly through our website. Clinics and prosthetists are eligible for wholesale pricing—please contact us through our site to be added to our professional network or to request more information.

Yes. The ProHensor was designed to be easily maintained and adjusted using standard tools available in most prosthetic clinics. The modular locking system includes a replaceable locking cartridge, which is designed to be checked or replaced annually. This supports an ongoing care relationship between the prosthetist and patient and also provides a recurring revenue opportunity for the clinic. Most service needs can be addressed in-clinic without requiring the device to be returned to the manufacturer.

Yes. We offer demo units for prosthetic clinics interested in evaluating the ProHensor for patient trials or training. Contact us to learn more about availability and terms.

We offer a variety of patient education materials, including video tutorials, printed quick-start guides, and direct support from our team. We also provide clinician-facing materials to support integration into your practice. As adoption grows, we will expand access to peer training and certified clinician resources.

We are collecting ongoing feedback from users and clinicians as part of our pilot programs. Preliminary results show increased prosthetic acceptance, improved functional use, and higher satisfaction rates compared to conventional split hooks. Additional data and case studies are forthcoming and will be available on our website.

1. The ProHensor is not currently PDAC-verified under existing codes such as L6722. Using standard codes may result in insufficient reimbursement. While we cannot directly recommend a specific code, we encourage clinicians to refer to our downloadable reimbursement guide to assist in describing the device accurately, documenting medical necessity, and navigating payer-specific processes.

The ProHensor is built for durability and long-term performance in real-world conditions. With regular care and annual maintenance—such as replacement of the locking cartridge—it is expected to last several years under active use.

Please reach out to us at support@marinsmed.com. Our team is available to assist with clinical guidance, technical support, and troubleshooting.

Patients may purchase the ProHensor directly through our website. However, we strongly encourage fittings and follow-up care through a certified prosthetist to ensure optimal alignment, comfort, and long-term success.

At Marins, we prioritize user-centered design and collaborative development with real amputees and clinical professionals. Our CTO is a 35-year upper-limb amputee who helped design the ProHensor based on experience. The ProHensor includes a field-serviceable locking cartridge, designed for annual replacement, supporting the clinical relationship between prosthetist and patient. We focus on practical innovation—devices that improve daily life, enhance control, and can be serviced and sustained over time. Our commitment to proprioceptive design, durability, and prosthetic acceptance sets us apart.
