Abstract
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.
