Patent number: 7037295Abstract: An apparatus and method for providing a co-extruded, tapered multi-layer shaft. A co-extruded, tapered multi-layer shaft may be fabricated by selecting a first material for the inner layer of the shaft and a second material for the outer layer of the shaft. The first and second materials are then co-extruded by a co-extrusion system including a puller with programmable tapering capabilities. The system forms a hollow tubing having an inner layer and an outer layer, wherein the tubing has the desired tapered characteristics. The result is a tapered tubular shaft having an inner layer and an outer layer.Type: GrantFiled: May 20, 2003Date of Patent: May 2, 2006Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Stephen J. Tiernan, Jeong S. Lee, Mina W. B. Chow, Stephen G. Schaible

Patent number: 6695812Abstract: A balloon catheter system generally having an elongated catheter shaft with enhanced flexibility to facilitate more distal advancement within a patient's body lumen. The catheter shaft has a relatively stiff proximal shaft section, a relatively flexible distal shaft section and an intermediate shaft section which provides a smooth, flexible transition between the proximal and distal shaft sections. The intermediate shaft section has an improved construction with a tubular reinforcing member secured by its proximal end to the distal extremity of the proximal shaft section and a distal end secured within the proximal end of the distal shaft section. The tubular reinforcing member preferably has an inner tubular support member which has a proximal end secured to the distal end of the proximal shaft section. Preferably, the proximal shaft section has an outer jacket which extends over the tubular reinforcing member of the intermediate shaft section.Type: GrantFiled: December 4, 2001Date of Patent: February 24, 2004Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Edward A.
