Publication number: 20040133158Abstract: An over-the-wire balloon dilatation catheter has a stainless steel hypotube catheter shaft, an intermediate sleeve section bonded to the shaft and a distal balloon section connected to the sleeve section. The sleeve section is formed from relatively flexible polymer materials and includes an inner core tube which defines a guide wire lumen extending only through a distal portion of the catheter (including its sleeve and balloon sections) to facilitate fast balloon catheter exchanges. A distal end of the hypotube shaft is crimped laterally and the core tube is nested and bonded within the crimp to provide a proximal outlet for the guide wire lumen. The hypotube shaft provides an inflation lumen for the balloon, with the inflation lumen being continued as an annular inflation lumen through the sleeve section where an outer sleeve is bonded about the core tube and extends from the distal end of the hypotube shaft to the balloon section.Type: ApplicationFiled: December 19, 2003Publication date: July 8, 2004Applicant: SCIMED LIFE SYSTEMS, INC.Inventors: Peter T.

Publication number: 20030212447Abstract: A delivery system for implantation of a self-expanding stent in a vessel consists of an elongate flexible catheter for delivering a self-expanding stent to a predetermined location in a vessel. The stent surrounds the flexible catheter near its distal end and is held in a delivery configuration where the stent has a reduced radius along its entire axial length by a stent retaining and release means. The stent retaining and release means is either one or more slipping sleeves which either contain the stent themselves or form a waterproof chamber with the stent being contained by water soluble bands or swelling bands. The stent retaining and release means can also be a pair of sleeves connected to hydraulic pistons, or a pair of sleeves connected to push/pull wires.Type: ApplicationFiled: May 13, 2003Publication date: November 13, 2003Inventors: Charles L.
