It’s not a HiFi,

Patents – IP – Products

Randall Alley is a well-known inventor of human performance products and attachment methods. At biodesigns, we don’t just innovate for users but innovate to push forward industries. In prosthetics, our goal is to replace Standard of Care (SOC) sockets with techniques founded on solid biomechanical principles, allowing wearers to achieve their full potential. In other sectors, it is breaking out of the norm to achieve ultimate performance. 

The Socket/Interface Revolution Started Here 

The HiFiTM Interface and HiFiTM Imager System took prosthetic sockets out of the dark ages. The HiFi, with  patented and patents-pending OsseostabilizedTM technology, is proven to achieve superior results. For far too long, wearers have been fit with flawed sockets, or as they say “buckets.” Those wearing sockets know something is wrong with existing approaches, yet the industry is slow to move. With the HiFi, biodesigns is committed to answering the calls from all those searching for a better solution.

NOTICE: Hanger’s Comfort Flex, Sabolich’s Socket, Lim’s Infinite Socket, Martin Bionic’s Socketless Socket, the MAS Socket and REVO Limb DO NOT have a license to our compression technology. If you are a prosthetist and believe you have been misled about your ability to use our technology in these other designs, please contact us. 

Training/Licensing Program 

We empower prosthetists by teaching them an improved clinical technique and system, backed by evidence-based clinical support, that will improve patients’ outcomes AND your bottom line. Whether you are a single practitioner, a large facility, or a teaching hospital, we have a licensing program to fit your needs. Learn more.

Development/Partnerships 

Randall is the co-inventor of the Push, Mag, and Click Valves, the first threadless valves for definitive sockets, acquired by ottobock, and the co-inventor of the Sure-Lok Cable Lock Control System and the Biomechanically Aligned Harness Anchor, two products to improve body-powered prosthetics, distributed by Fillauer.
