Abstract
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 of at least two different thermoplastic polymers, one of the thermoplastic polymers being a thermoplastic liquid crystal polymer (LCP) having a melting point of less than 250.degree. C. The portion of the device made from the melt blend may be a catheter body segment or a balloon for a catheter. The LCP blends suitably also include a non-LCP base polymer having a melting point in the range of about 140.degree. C. to about 265.degree. C.
