Publication number: 20160310706Abstract: A guide wire having a non-metallic, non-woven core wire is disclosed. Monofilar, polymeric fibers of multifilar helically-wound non-metallic fibers are preferred core wire materials. The guide wire optionally includes further coatings and other materials on the core wire. In one embodiment, a non-metallic distal coil wire is disclosed. The guide wire of this invention is particularly useable for magnetic resonance imaging applications.Type: ApplicationFiled: July 7, 2016Publication date: October 27, 2016Inventor: Mark G. Fleischhacker

Patent number: 6685696Abstract: A hollow lumen cable is formed by helically winding inner and outer coils with the helices of each coil being in an abutting relationship and the outer coil inner peripheral diameter being less than the outer peripheral diameter of the inner coil. Preferably, each coil is multifilar. After the coils are wound, an unwinding force is applied to the outer coil and the inner coil is inserted into the outer coil to have its winding inclined opposite to that of the outer coil; and thence, the outer coil is allowed to contract to form an interference fit with the inner coil. The cable may be incorporated as part of a medical apparatus. The cable is bendable about the tight radii and has a high torque transfer resolution while having a small cable outer diameter, a relatively long life, and has a hollow lumen in which there is no structure or through which fluid, wires or medial devices may pass.Type: GrantFiled: February 9, 2001Date of Patent: February 3, 2004Assignee: Lake Region Manufacturing, Inc.Inventors: Mark G. Fleischhacker, Joseph F. Fleischhacker, Jr., Thomas E. Hargreaves, Donald W. Hanson

Patent number: 6210395Abstract: A hollow lumen cable is formed by helically winding inner and outer coils with the helices of each coil being in abutting relationship and the outer coil inner diameter being less than the outer coil inner diameter being less than the outer, peripheral, diameter of the inner coil. Preferably, each coil is multifilar. After the coils are wound, an unwinding force is applied to the outer coil and the inner coil is inserted into the outer coil to have its winding inclined opposite to that of the outer coil; and thence, the outer coil is allowed to contract to form an interference fit with the inner coil. The cable may be incorporated as part of various medical systems e.g., implantable pumps or other rotatable medical apparatuses. The cable is bendable about the tight radii, has a high torque transfer, a small outer diameter, and a hollow lumen through which fluid, wires or medial devices may pass.Type: GrantFiled: October 20, 1997Date of Patent: April 3, 2001Assignee: Lake Region Mfg., Inc.Inventors: Mark G.
