Abstract: An implantable lead having an elongated lead body that includes an electrical conductor extending between a distal end of the lead body and a proximal end of the lead body is disclosed. The lead further includes an electrode formed at the distal end of the lead body, the electrode being coupled to the electrical conductor and one or more passive fixation mesh sections coupled to the distal end of the lead body that promotes tissue over growth.

Abstract: An implantable myocardial stimulation lead comprises a lead body having a distal end and a proximal end, and an electrical connector carried by the proximal end of the lead body. An electrode header carried by the distal end of the lead body has an axis and includes a helical fixation element extending along the axis, the electrode header having a surface configured to receive a driver for rotating the electrode header to screw the helical fixation element into the tissue of the heart. The lead body carries along its length a strain relief member resisting excessive bending of the lead body.

Abstract: Features for a high performance prosthetic foot are provided in a package suitable for use with Symes and reverse-Symes amputees. The foot has a very low profile despite incorporating ankle-type torsional features complete with biasing. Other optional features are presented by way of a dual-rate padding spring system, that convincingly allow for both walking and running (together with related tasks like jumping) by way of a single prosthetic setup. Additional features may be provided in the padding springs directed toward more natural foot movement and response. The foot may be provided alone, in connection with a prosthetic socket and be bare or encased in order to appear more natural.
