Filed:

Jan 31, 2008

Appl. No.:

12/023817

Inventors:

John M. Swoyer - Andover MN, US
Keith Carlson - Minneapolis MN, US
Martin T. Gerber - Maple Grove MN, US
George J. Mano - Ellicott City MD, US
Michele Spinelli - Milan, IT
Steven David Hartle - Eden Prairie MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/18

US Classification:

607116

Abstract:

An implantable medical electrical lead particularly for stimulation of the sacral nerves comprises a lead body extending between a distal end and a proximal end, and the distal end having at least one electrode of an electrode array extending longitudinally from the distal end toward the proximal end. A fixation mechanism is formed on or integrally with the lead body proximal to the electrode array that is adapted to be implanted in an engage subcutaneous tissue, particularly muscle tissue, to inhibit axial movement of the lead body and dislodgement of the stimulation electrodes.

Abstract:

A hydrostatic power steering device (11;111) is provided of the type including a primary, spool valve (35;135), and a follow-up, sleeve valve (37;137). During normal operation, relative rotation of the spool and sleeve define one or more variable flow control orifices (A1A5; AN; A1) and these orifices have a first area versus deflection relationship when the sleeve is biased to its first position (FIG. 5; FIG. 10). The sleeve may be moved toward a second position (FIG. 6; FIG. 11) in response to an input (95, 99) other than rotation of the vehicle steering wheel. In the second axial position of the sleeve, the flow control orifice has a different area versus deflection relationship, the difference providing a useful steering or ancillary function.
