HiFi Training and Licensing Program

HiFi Prosthetist Training 

Randall Alley, HiFi Inventor, is training and licensing facilities in his Upper and Lower Limb HiFi Prosthetic Interface System. Thousands of wearers enjoy the benefits of the HiFi under the care of a select group of clinicians in the US and abroad. As a HiFi Authorized Provider you will improve your patients’ lives with an alternative to SOC sockets, differentiate your practice, attract new patients, improve patient loyalty, bill additional codes, and be part of the growing HiFi Network.

HiFi Interface Benefits – Putting Your Patients First

The patented and patents-pending HiFi System is a revolution in interface technology. Clinicians can either lead with a proven, better fitting and functioning interface system or continue to utilize socket designs that are plagued with so many inherent issues, including pain, rubbing, skin breakdown, pistoning, falls, slow walking speeds, instability, increased energy, sound side breakdown, volume fluctuation, decreased proprioception, and the list goes on. Time to step-up to the HiFi. Learn more about the HiFi.

HiFi Imager Benefits – Our Quest to Standardize the Casting/Scanning Process

The patented HiFi Standing Imager and HiFi Hand-Held Freestyle Imager are critical components of the HiFi Process. During casting or scanning, clinicians can impart optimum and consistent levels of compression in distinct areas on the wearer’s limb while wearers provide dynamic feedback. This active feedback and diagnostic input during the image capture process will be the new standard in prosthetics. Patients will receive a better fitting diagnostic socket, while saving a clinic time and valuable resources. The final result will be a more intimate, more comfortable, higher performing interface, without the typical issues associated with other sockets, and with lower trim lines, including subischial for femoral applications.

Choosing Science over Art 

We’re always disappointed when a prosthetist or allied health professional, after seeing the clinical evidence and research supporting the HiFi’s OsseostabilizingTM technology dismisses it as “just another option.” At biodesigns, we embrace patient choice and system options, but not at the detriment of the patient’s well being, mobility, rehabilitation, function and quality of life. Everyone agrees that current sockets are flawed and cause numerous problems. The HiFi technology is a paradigm shift as we utilize our patented and patents-pending compression technology to reduce unwanted motion of the bone and sync prosthetic motion more closely to skeletal motion, improving performance for both upper and lower limb prosthetic wearers. No other socket has the long list of benefits provided by the HiFi. Sometimes humor can be the most effective means for change.

HiFi Simplicity and Time Savings

We know other socket companies have promised you the moon, but it didn’t exactly work out the way you hoped. Not as simple or effective as they appeared to be in marketing. Not the degree of patient acceptance you had hoped for. With the HiFi you will realize the ROI and save 100s of man-hours creating a lasting interface solution that doesn’t need constant adjustments. Once you master the design, you no longer will need to make test socket after test socket, chasing your tail to try and fit a bucket to a dynamic limb. The answer doesn’t lie in adding adjustability or 3D printing to a SOC bucket. Neither does it lie in a collection of pads and straps cobbled together to look like a socket. The answer doesn’t lie in sucking all the air out of a bucket with an expensive fish pump or by rolling on the next generation of liner. The answer lies in INTERFACE BIOMECHANICS, pure and simple. When you utilize our proven system, you get rid of the guesswork. Since we gain nearly all our stability along the shaft of the bone, we no longer have to strangle the patient’s limb at the proximal brim. There goes all your major issues: adductor rolls, damaged skin, discomfort in the ischial/ramus area, overly tall and aggressive trim lines, etc. And because we don’t have anything more than a soft and gentle proximal trim line, it takes only a few minutes to create the brim.

HiFi Billings/Reimbursement

The way forward is not downward. We believe by demonstrating your enhanced skill by providing this advanced interface technology, you should get paid for it. Many other socket companies, along with a few manufacturers and even prosthetists (go figure) are trying to get rid of YOU and your ability to get paid by offering to eliminate test sockets, ship you adjustable kits, offer sockets by numbers and pretty much open the floodgates for eliminating the skilled prosthetists. Thankfully, none of these products will yield the superior results of the HiFi. So what type of prosthetist are you? One that accepts crappy contracts, or cuts important corners, or fits patients in systems that are less work for you but not better for your patien. Or someone who recognizes the opportunity that exists in the vacuum left behind by those prosthetists that were replaced by techs, therapists and central fabrication. With the HiFi training –  we are exclusive. We only want those facilities interested in superior clinical care and improved patient outcomes to be a part of our network. To the rest of you who aren’t interested, we wish you good luck.

HiFi Patents/IP/Licensing

The HiFi technology is responsible for starting the 21st century socket revolution. With over 15 patents and numerous patent-pending applications, the HiFi is well protected. While some will try and imitate the HiFi, it is not a HiFi unless it says HiFi. The HiFi is a proven design that was tested with physician oversight as part of DARPA’s Revolutionizing LUKE Arm project, and was part of numerous clinical studies, several in conjunction with the VA. However, if done incorrectly or without Authorized Training, the HiFi will have poor results. biodesigns is the only company authorized to provide HiFi training and licensing. View Patent Portfolio.

HiFi Training/Licensing Fees

We provide prosthetists with the tools and techniques to make them better – we provide the fishing pole,  not the fish. By elevating the skill of the prosthetist, we can have the greatest impact on improving the clinical care of the patient and thus improving outcomes, while demanding improved reimbursement. In order for us to best determine the model most appropriate for you/your facility, we need a little information. Contact us with your specific needs and we will customize a licensing program especially for you. Whether it is our comprehensive HiFi Custom Program or our latest HiFi Digital Program, you and your patients will realize the many benefits of the HiFi System.
