Biomimetic Hip Prosthesis

Rensselaer Polytechnic Institute, 2000 - $5,500

The major limiting factor in the lifetime of total hip prosthesis is wear and its incumbent problems. The current implant lifetime is ten or fifteen years, which is typically insufficient for most active patients, and revision surgeries are often necessary.

This grant supported the development of patent protection and the pursuit of licensing agreements for a novel approach to increasing the durability of artificial replacement hip joints. The team consisted of one student and a broad group of advisors working to develop basic technology sufficient to obtain patent protection and initiate licensing arrangements.

The innovation is a method of mimicking the lubrication capabilities of natural cartilage with a synthetic matrix containing molecules that mimic the weeping and ionic re-uptake of synovial liquid that protects the bearing surfaces.
