Abstract
A medical electrical lead includes a tapered distal tip having a tapered drug-eluting component incorporated therein. The drug-eluting component can be an overmolded drug-eluting collar or a pre-molded drug eluting collar. The drug-eluting collar is disposed in a recess formed in the tapered distal tip and maintains the overall tapered profile of the distal tip.
Claims12
An implantable medical lead, comprising:
- a lead body including a proximal end adapted to be coupled to a pulse generator and a distal region including a distal tip having an outer surface having a tapered cross-sectional profile extending from a proximal end of the distal tip to a distal end of the distal tip;
- a ring-shaped electrode located on the lead body proximal of the tapered cross-sectional profile of the distal tip;
- a recess formed in and extending along the outer surface of the distal tip;
- at least one conductor extending within the lead body from the proximal end to the ring-shaped electrode, the ring-shaped electrode operatively coupled to the at least one conductor;
- and
- a drug-eluting component disposed in the recess formed in the distal tip, wherein the drug-eluting component has a tapered cross-sectional profile corresponding to the tapered cross-sectional profile of the distal tip such that the tapered cross-sectional profile of the outer surface of the distal tip extends distally from the drug-eluting component.

An implantable medical lead, comprising:
- a lead body including a proximal end adapted to be coupled to a pulse generator and a distal region including a distal tip having an outer surface defining a tapered cross-sectional profile extending from a proximal end of the distal tip to a distal end of the distal tip and a recess formed in and extending along the outer surface of the distal tip such that the recess extends around an entire circumference of the tapered distal tip;
- a ring-shaped electrode located on the lead body proximal of the tapered cross-sectional profile of the distal tip;
- at least one conductor extending within the lead body from the proximal end to the ring-shaped electrode, the ring-shaped electrode operatively coupled to the at least one conductor;
- and
- a circumferential drug-eluting collar disposed in the recess formed in the distal tip, wherein the drug-eluting collar has a tapered cross-sectional profile corresponding to the tapered cross-sectional profile of the distal tip and extends around the entire circumference of the tapered distal tip, the tapered cross-sectional profile of the outer surface of the distal tip extending distally from the drug-eluting collar.
