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.

An elongate support member for use with catheters, comprising:
- a proximal end;
- a distal end;
- the distal end connected to a mid-region comprising a proximal and distal end, the distal end of the mid-region connected to a distal region;
- a plurality of flanges;
- a linkage connecting the flanges;
- and
- a lumen defined by connecting the flanges.
An elongate support member for use with a catheter, comprising:
- a metallic object;
- the metallic object formed to define a plurality of flanges, a proximal end, and a distal end;
- the distal end connected to a mid-region comprising a proximal and a distal end, the distal end of the mid-region connected to a distal region;
- a linkage connecting the flanges;
- a lumen defined by connecting the flanges;
