Patent ID: 7101597

Claim:
A medical device at least a portion of which is composed of a polymeric material in which the polymeric material is a melt blend product comprising at least two different thermoplastic polymers, one of the thermoplastic polymers being a thermoplastic liquid crystal polymer (LCP) in an amount of about 0.1 to about 20 weight percent, the LCP having a melting point of less than 250° C. and which is a member selected from the group consisting of polyesters, wholly aromatic polyesters, wholly aromatic copolyesters, partially aromatic polyesters, partially aromatic copolyesters and polyesteramides and a thermoplastic non-LCP base polymer in an amount of about 50 to about 99.9% by weight, the base polymer having a melting point in the range of about 140° C. to about 265° C.; wherein the LCP stays separated on a microscopic level during solidification of the melt blend so that the LCP discontinuous chase is microscopically distributed in the continuous base polymer phase.
