Abstract
In one embodiment, the present invention provides a cardiac lead including a fixation member extending from a distal end of the lead. The fixation member includes a coated portion and an uncoated portion. The coating that forms the coated portion includes a biocompatible polymer material and a therapeutic agent. The coating may provide for the delivery of the therapeutic agent directly at the sight of fixation for an extended period of time.
Claims22
A lead for use in a cardiac rhythm management system, the lead comprising:
- a lead body including a proximal end and a distal end and a conductive member extending between the proximal and distal ends;
- a fixation electrode coupled to the lead body and in electrical communication with the conductive member;
- and
- a biocompatible coating applied over a portion of the fixation electrode, the coating including a polymeric material and a therapeutic agent.
A cardiac rhythm management system comprising
- a pulse generator;
- a lead having an electrode and a proximal end adapted for coupling with the pulse generator;
- a coating means for providing an extended release of a anti-inflammatory therapeutic agent, the coating means being disposed over a portion of the electrode;
- and
- means for affixing the lead in a patient.
A method of coating a cardiac lead electrode comprising:
- providing a coating mixture including a polymeric material and a therapeutic agent;
- applying the coating mixture onto the electrode such that the electrode includes a coated portion and an exposed portion;
- and
- treating the coating mixture to form a coating on the electrode.
