摘要： 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. A kink-resistant coil structure extends distally from the distal end of the hypotube shaft to provide a gradual change in stiffness along the length of the catheter from the relatively stiff hypotube shaft to the relatively flexible distal portion of the catheter.

摘要： A fixed wire balloon catheter for use in angioplasty includes an elongated flexible thin walled metal tube which carries an inflatable balloon at its distal end. A metal core member of smaller outer diameter meter than the metal tube is attached to the distal end of the tube to provide support for and guiding of the balloon section. The proximal end of the balloon is connected either to the distal end of the metal tube or to an intermediate waist tube, with the core extending distally from the metal tube through the balloon. The distal end of the balloon is secured to the core. A vent arrangement is provided to purge the catheter of gases prior to use.

摘要： The balloon of an angioplasty balloon catheter is prepared for insertion through a patient's cardiovascular system by a series of steps to create three or more folded wings or flaps. The wings are wrapped circumferentially to provide a minimized outer diameter when the balloon is in its deflated state.

摘要： An over-the-wire balloon dilatation catheter has a stainless steel hypotube catheter shaft having a partially collapsed distal region. The partially collapsed region has a convex radius and a concave radius with the degree of collapse increasing distally while maintaining patency. The catheter includes a tubular element which overlaps a distal portion of the partially collapsed region, said tubular element comprising a wire coil disposed about its proximal region and being sealingly bonded within the concave partially collapsed region. The bonding region of the catheter shaft and tubular element is further sealingly disposed within the proximal end of a distal tubular member having a distal inflatable region. The distal end of the tubular element is sealingly disposed within the distal end of the distal tubular member.
