Filed:

Dec 27, 2000

Appl. No.:

09/749646

Inventors:

Patricia M. Derus - Rogers MN
Sidney F. Hauschild - Brooklyn Park MN
Mark Polyak - Minnetonka MN
George Michael Huepenbecker - Vadnais Heights MN

Assignee:

American Medical Systems Inc. - Minnetonka MN

International Classification:

A61F 226

US Classification:

600 40, 417441

Abstract:

A pump assembly for a penile implant is provided having a mechanism that prevents spontaneous inflation of the cylinders implanted within the patient. The preventative mechanism includes a switching mechanism for moving a valve into either a closed or an open position. When closed, the locking valve prevents fluid flow in an adverse direction. While open, the pump functions normally allowing the cylinders to be inflated.

International Classification:

A61N 105

US Classification:

607122, 607127, 600375

Abstract:

A medical electrical lead is provided that is readily manufactured using a minimal number of parts, has a reduced size and improved reliability during implantation and extraction. The lead includes a modular electrode head assembly that is joined to a lead body at a butt joint. The butt joint is stabilized in at least four possible ways: insulation tubing that spans the joint is bonded to the electrode head assembly; two cabled conductors extending the length of the lead body are coupled to the electrode head assembly; an electrode head alignment peg interlocks with and is bonded to the lead body; and a coil electrode is positioned across the butt joint on the outer diameter of the assembly and the lead body. The lead size is minimized by using a compact retraction stop mechanism, a low-friction, press-fit drive shaft seal, and a small diameter coiled conductor insulated by a thin-walled insulating tube.

International Classification:

A61N 1/00

US Classification:

607116

Abstract:

A medical electrical lead that includes a lead body having a lead body lumen, an electrode head assembly fixedly engaged with the lead body and having an electrode head assembly lumen communicating with the lead body lumen, and a conductor extending within the lead body lumen and the electrode head assembly lumen. An insulating member extends through the electrode head assembly lumen and the lead body lumen to electrically isolate the conductor.

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/03

US Classification:

607122

Abstract:

An implantable lead which has an increased resistance to fracture and has the capability of continued function after fracture of a conductor. The lead is provided with a coiled conductor which may be monofilar or multifilar and which extends along the length of the lead, running from an electrical connector at the proximal end of the lead to an electrode at or near the distal end of the lead. In addition, the lead is provided with a stranded conductor which is electrically coupled to the coiled conductor at point along the lead body located proximal to the point of expected breakage of the coiled conductor and at a point along the lead body located distal to the point of expected breakage. The proximal and distal ends of the stranded conductor in some embodiments are also mechanically coupled to the coiled conductor.

Timothy G. Laske - Shoreview MN

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 105

US Classification:

607122

Abstract:

An implantable electrical lead having at least two mutually insulated electrical components that are separated by a portion of the lead's body fabricated of a plant, extensible biocompatible insulated material. An extensible conductor extends from the proximal end of the lead body to a first one of the electrical components, and a second, inextensible conductor extends from the proximal end of the lead body to a second one of the electrical components. An inextensible reinforcement member is coupled to the inextensible conductor and extends distally from the second electrical component to the first electrical component and is coupled mechanically to the first electrical component.
