Filed:

Feb 9, 2001

Appl. No.:

09/780658

Inventors:

Mark G. Fleischhacker - Minnetonka MN
Thomas E. Hargreaves - Mound MN
Donald W. Hanson - Chanhassen MN

Assignee:

Lake Region Manufacturing, Inc. - Chaska MN

International Classification:

A61M 2500

US Classification:

604526

Abstract:

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. Also, there is a handle assembly for operating a movable guide wire between positions for straightening the guide wire and allowing it to assume its generally J-shape.

Inventors:

Mark Fleischhacker - Minnetonka MN, US

International Classification:

A61B005/00

US Classification:

600/585000

Abstract:

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.

Abstract:

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 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 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.

Abstract:

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. For example, the cable distal end is connected to an implantable pump or other rotatable medical apparatus and the proximal end to a powered prime mover. A manually operated control member is attached to the cable proximal end portion, and the distal end to a medical sub-assembly such as a forceps or cutter; or as a part of a guide wire, or as part of a catheter to impart torque control. 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 medical devices may pass.
