Patent number: 6482348Abstract: A method of forming a balloon for medical purposes comprising co-extruding in a tubular shape a base structural layer of a member selected from the group consisting oft polyamides, polycarbonates, polyesters and copolymers thereof and a heat sealable layer selected from the group consisting of polyethylene and copolymers thereof. The tubular member is then biaxially oriented by inflating the tube with a gas to a predetermined central diameter greater then the initial diameter of the tube and simultaneously heating the inflated tube to a temperature sufficient to biaxially orient the base structural layer. The member is then cooled the inflated tubular member and then elevated in temperature for a second time to the biaxially orienting temperature. The twice-heated tube is allowed to cool and the gas is withdrawn whereby the tubular member will assume a generally tubular shape and the main structural layer will remain biaxially orientated and the heat sealable layer will not be biaxially orientated.Type: GrantFiled: April 3, 2000Date of Patent: November 19, 2002Assignee: Boston Scientific CorporationInventors: James C.

Patent number: 6436056Abstract: Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.Type: GrantFiled: July 13, 1998Date of Patent: August 20, 2002Assignee: Boston Scientific CorporationInventors: James C.

Patent number: 6135992Abstract: A medical device, such as a catheter in which the catheter has a relatively stiff proximal section and a relatively soft distal section joined by a relatively short transition section in which the materials of the proximal and distal sections are gradually combined in the transition section to form a continuous unbroken tube without abrupt joints. The relatively soft distal section can be provided with a balloon, and the catheter can be provided with multiple passageways. In addition, the catheters can be provided with braiding to provide the finished product with more torqueability and kink resistance.Type: GrantFiled: April 21, 1997Date of Patent: October 24, 2000Inventor: James C.
