Abstract:
The invention comprises self-lubricating polymer compositions that are especially useful in medical devices and valves and gaskets of medical devices. In a preferred embodiment, the polymer compositions comprise a thermosetting or thermoplastic silicone elastomer in combination with a lubricity enhancing polyfluoropolyether fluid or hydrocarbon-based synthetic oil. In other preferred embodiments, the polymer compositions contain only biocompatible components. The improved anti-friction properties of the self-lubricating polymers can be demonstrated over a course of insertion and withdrawal cycles, where conventional polymers have changing and mostly increasing force required for each insertion and withdrawal, while the polymer compositions of the invention remain stable.

Claim (Index 1):
A biocompatible, self-lubricating polymer composition consisting essentially of:\n a polymer matrix of dimethyl and methylvinyl siloxane copolymers, wherein the polymer matrix is selected from the group consisting of: (a) a polymer matrix, measured as in-mold cured for 10 minutes at 116\u00b0 C., that has a specific gravity of 1.11, a durometer of 22 in Shore A hardness scale, and a tensile strength of 1347 psi and (b) a polymer matrix, measured as in-mold cured for 10 minutes at 116\u00b0 C., that has a specific gravity of 1.12, a durometer of 35 in Shore A hardness scale, and a tensile strength of 1427 psi, and a polyfluoropolyether (PFPE) synthetic oil at a concentration of about 1 to about 20 parts per hundred by weight (phr), wherein the PFPE synthetic oil migrates through the polymer matrix during the use of the biocompatible, self-lubricating polymer composition, and wherein the migration of PFPE synthetic oil maintains consistent surface lubricity when exposed to frictional force.
