摘要： 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° 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° C. to about 265° C.

摘要： A tubular parison for forming a medical device balloon. The parison is formed of a polymeric material, for instance a thermoplastic elastomer. The parison has an elongation at break which is not more than 80% of the elongation of the bulk polymeric material. The elongation of the parison is controlled by altering extrusion conditions. Balloons prepared from the parisons provide higher wall strength and/or higher inflation durability than balloons prepared from conventional parisons of the same material.

摘要： An apparatus and method for molding balloon catheters is disclosed. The balloon may be molded by providing a polymeric tube within a mold having an interior cavity in the shape of the desired balloon. Microwave energy, which may be generated by a gyrotron, may then be directed toward the mold, to heat the polymeric material without heating the mold. Once heated, pressurized fluid may be injected into the tube to blow the polymeric material against the interior cavity whereupon the material can cool to form the balloon or can be further heatset by additional microwave energy and be cooled to form the balloon. In accordance with one embodiment, microwave energy can also be used without a mold to form a medical device.

摘要： A stent includes a main body of a generally tubular shape for insertion into a lumen of a vessel of a living being. The tubular main body includes a substantially biodegradable matrix having collagen IV and laminin that enclose voids within the matrix. The tubular main body also includes a biodegradable strengthening material in contact with the matrix to strengthen the matrix. The tubular main body is essentially saturated with drugs.

摘要： The present invention relates generally to elongate support members, preferably for use with a catheter for performing medical procedures including percutaneous transluminal coronary angioplasty. An elongate support member, comprising a proximal end, a distal end, is disclosed. The proximal end of the elongate support member, is formed to define a plurality of flanges. A linkage connects the flanges, and a lumen within the shaft defined by connecting the flanges. The elongate support member comprises an improved catheter shaft design that maintains pushability, flexibility, and torquability while limiting the kinking.
