Patent number: 8603066Abstract: The instant invention relates generally to catheters and to introducer catheters used to help deliver catheters or other medical devices to locations within the human body. In particular, the instant invention relates to large diameter catheters and introducer catheters having a torque transfer layer that includes at least two flat wires braided into a wire mesh. The flat wires have a width of at least about 0.007 inches and a depth of at least about 0.003 inches. The lumen diameter of the catheter is at least about 6 French. The torque transfer layer provides increased strength, flexibility, and kink resistance.Type: GrantFiled: March 8, 2011Date of Patent: December 10, 2013Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Wayne Heidman, Allan Fuentes, Richard E.

Publication number: 20080234660Abstract: A catheter assembly includes an inner liner made of flexible material and an outer layer having a steering mechanism. The steering mechanism includes at least one flat wire and a corresponding lumen through which the flat wire may travel. The steering mechanism may also include at least one pull ring to which the flat wires are attached. A layer of heat shrink material may encompass the outer layer. A braided wire assembly, which may have a braid density that varies along the length of the catheter, may also be provided in the outer layer. The overall cross-section of the catheter assembly is preferably substantially circular. A catheter shaft may include a plurality of segments of differing hardness characteristics. The outer layer typically comprises a melt processing polymer such that the catheter assembly may be laminated using heat.Type: ApplicationFiled: December 29, 2006Publication date: September 25, 2008Inventors: Sarah Cumming, Mark Dustrude, Allan Fuentes, Wayne Heideman, Richard Stehr

Publication number: 20060151923Abstract: The present invention is a method of manufacturing a flexible tubular body for catheter, sheath or similar medical device. The method comprises pre-extruding an inner layer of the body from a thermoplastic polymer and then pulling the inner layer over a mandrel and tightening the layer down. If wire lumens were not integrally formed in the inner layer when pre-extruded, then two polymer spaghetti tubes, each with wire lumens, are laid 180 degrees apart axially along the outer surface of the inner layer. Deflection wires are then fed into the wire lumens. A cylindrical wire braid is woven or pulled over the inner layer (and the spaghetti tubes, as the case may be) and tightened down. The aforementioned components are then encased in an outer polymer layer. A heat-shrinkable tube is then placed over the outer layer.Type: ApplicationFiled: January 10, 2005Publication date: July 13, 2006Inventors: Eric Wilkowske, Allan Fuentes, Xiaoping Guo, Xuan Khieu, Linda Nemec, Richard Stehr
