Official title
An Osseointegrated Transtibial Prosthesis Offering Long-Term Bi-Directional Efferent-Afferent Neural Transmission
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The e-OPRA Implant System, is a further development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System. The e-OPRA Implant system is an implant system for direct skeletal anchorage of amputation prostheses. The added feature in the e-OPRA Implant system, is a bidirectional interface into the human body that allows permanent and reliable communication using implanted electrodes. These electrodes will provide long-term stable bioelectric signals for an improved control of the prosthetic limb. The purpose of the study is to evaluate the feasibility of a transtibial amputee with the e-OPRA Implant System exhibiting full neural control over a neuro-mechanical prosthetic system. A maximum of two subjects will be enrolled. Each subject will undergo a surgery where the e-OPRA Implant System will be implanted. The subjects will participate in follow-up sessions of which the last one occurs approximately 24 months after the surgery. This is a prospective, non-randomized, uncontrolled study.
