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: 5984877Abstract: An apparatus and method of providing radiopaque marking for a coil spring. The coil spring will typically be used for medical applications within the cardiovascular system or other region wherein the assistance of a spring guide wire is necessary or desirable. Likely applications may include guide wires, angioplasty catheters, or infusion catheters. The basic spring guide wire is formed of a multifilar (e.g. quadrifilar) structure. At least one of the wires within the quadrifilar structure is drawn from a highly radiopaque material, such as platinum or a platinum alloy. The remaining wires are of a convenient base material such as stainless steel. The resulting quadrifilar structure will provide a degree of radiopacity over its length with one of four strands being highly visible under fluoroscopic energy. Various points along the spring guide wire may be further distinctively marked by changing the number of strands within the multifilar structure.Type: GrantFiled: February 5, 1991Date of Patent: November 16, 1999Inventor: Joseph F. Fleischhacker, Jr.

Preferably, each coil is multifilar. After the coils are wound, an unwinding force is applied to the outer coils and the inner coils is inserted into the outer coils to have its winding inclined opposite to that of the outer coil; and thence, the outer coils 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 apparatus. 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 medical devices may pass.Type: GrantFiled: October 13, 1992Date of Patent: October 21, 1997Assignee: Lake Region Manufacturing, Inc.Inventors: Mark G.

Patent number: 5433200Abstract: A guide wire having a solid core wire which runs its entire length. The core wire has a proximal portion which constitutes the majority of its length and which tapers to a distal portion. The distal portion terminates in an atraumatic tip at the extreme distal end of the guide wire. In one embodiment a portion of the distal segment of the core wire adjacent the tip is flattened. The guide wire further includes an integral, flexible, flat wire coil attached to the core wire at its taper and to the core wire distal tip and running the entire distance therebetween. Lastly, the flattened wire coil has a non-metallic lubricous or hydrophilic coating on at least a portion of its exterior. In a preferred embodiment the proximal portion of the core wire tapers to a second diameter medial portion or segment which itself tapers to a third diameter distal segment.Type: GrantFiled: November 16, 1992Date of Patent: July 18, 1995Assignee: Lake Region Manufacturing, Inc.Inventor: Joseph F.

Patent number: 5069217Abstract: A steerable guide wire for use in a medical procedure, such as coronary angioplasty, which requires positioning a catheter or other device at a remote location within the body by way of the cardiovascular system or other passage way. The guide wire has a solid core wire which runs the entire length. The distal end of the core wire is tapered to an intermediate diameter to permit insertion into a short flexible coil, or a combination of a flat wire coil and round wire coil attach to each other at a brazed joint. The flexible coil has an outside diameter approximately equal to the outside diameter of the core wire proximal to the taper. The proximal end of the flexible coil is fixedly attached to the taper. The distal tip of the core wire is further tapered and optionally flattened to enhance the handling characteristics as well as flexibility. The distal tip of the core wire and a flexible round wire coil are coextensive, and attached distally to form a smooth tip for the guide wire.Type: GrantFiled: July 9, 1990Date of Patent: December 3, 1991Assignee: Lake Region Manufacturing Co., Inc.Inventor: Joseph F.

Patent number: 3973556Abstract: A coil spring guide, for use in connection with the insertion of a catheter into the vessels of a body, that has a coil spring, and a wire core extending within the coil spring and having a distal end welded to the distal end of the coil spring. The coil spring is made from metal wire that in a straightened condition is circular in transverse cross section throughout its length, and that after being coiled, to have adjacent helics abut against one another. Thereafter the radially outer circumferential portion of the coil is ground away to provide a helical radially outer spring coil surface (chordal surface) that is of a substantially constant radius throughout the axial length of the coiled wire and has a helix width of a chord parallel to the central longitudinal axis of the coil spring that is subtended by about a 10.degree.-140.degree. angle of two radii of the coil spring wire.Type: GrantFiled: June 20, 1975Date of Patent: August 10, 1976Assignee: Lake Region Manufacturing Company, Inc.Inventors: John J.
