Abstract:
1. An implantable electrical lead, comprising: an elongate flexible lead body having a distal portion; a plurality of substantially axially coextensive resilient tissue engaging members disposed at the distal portion of the lead body and configured to be controllably expandable from a retracted state to a radially extended state so as to engage adjacent target tissue, distal tips of the tissue engaging members being sharp and configured to penetrate the adjacent target tissue, and the plurality of tissue engaging members disposed radially outwardly and distally when in the radially extended state such that the distal tips of the tissue engaging member are oriented in a distal direction to penetrate the adjacent target tissue; an axial displacement mechanism mechanically coupled to the tissue engaging members; at least one electrode disposed at the distal portion of the lead body; a connector disposed at a proximal end of the lead body and having at least one conductive terminal; and at least one conductor cable in electrical communication between respective electrodes and conductive terminals of the connector.
