Patents – IP – Products

Randall Alley is a well-known inventor and has developed numerous human performance products and attachment methods that span across multiple sectors. At biodsigns, we don’t just innovate for end-users, but innovate to help push forward a profession or industry. In prosthetics, our goal is to replace the current Standard of Care (SOC) interface designs  with approaches, tools and techniques that are founded on solid biomechanical principles, allowing you to do more and achieve your full potential…not just get by. In other industries, it is breaking out of the norm of what is accepted and possible to achieve ultimate performance. 

The Socket/Interface Revolution Started Here 

Thanks to the High-FidelityTM Interface and HiFiTM Imager System, we took prosthetic socket designs out of the dark ages. The HiFi was the first of its kind and a game changer in O&P with our patented and patents-pending compression and release OsseostabilizedTM technology, proven to achieve superior results for wearers. For far too long, wearers have been fit with biomechanically-flawed sockets, or as our patients state, “buckets.”  Those wearing the sockets intuitively know something is wrong with existing, Standard of Care Sockets, yet the profession is slow to move with many being stuck in their ways. With the HiFi , biodesigns is committed to answering the calls from all those patients looking for a better solution.

The HiFi Interface Patent Portfolio includes method and utility patents, from traditional fabrication to modular designs. If you believe you are utilizing our patented or patents-pending compression technology, contact us to learn about our licensing program.
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 bone-stabilizing and bone controlling HiFi interface technology. If you are a prosthetist and believe you have been misled about your ability to use our compression and release technology in these other designs, contact us. 

Training and Licensing Program 

We believe in the skill and talent of the prosthetist. With the HiFi Interface System, we empower the prosthetist by teaching them a new and 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. We also offer a license for traditional, adjustable, and modular applications. Learn more.

Product Development/Partnerships 

Randall is the co-inventor of the Push, Mag, and Click Valves, the first threadless valves for definitive sockets introduced into prosthetics and acquired by Ottobock.
He is also the co-creator of the Sure-Lok Cable Lock Control System and the Biomechanically Aligned Harness Anchor, two products to improve body-powered prosthetics, manufactured and distributed by TRS Prosthetics.

Beware of prosthetists attempting to provide you will HiFi Interface impostors, imitators, and wannabees as they may cause you injury.
