Abstract
A lumen seal of a medical electrical lead includes an outer surface adapted to form a portion of an exterior surface of the medical electrical lead and an inner surface adapted to seal off a lumen of the lead and yet allow passage of an elongate member that is slidably engaged within the lumen of the lead. The seal further includes a portion in which an agent is embedded, the agent adapted to disperse from the portion out through the outer surface of the seal.
Claims10
A medical electrical lead, comprising:
- an elongate lead body including a lumen extending therethrough, an external surface and a distal portion;
- an electrode coupled to the distal portion of the lead body;
- and
- a resilient element coupled to the distal portion of the lead body in close proximity to the electrode, the resilient element comprising:
- an outer surface forming a portion of the external surface of the lead body,
- an inner surface adapted to seal off the lumen of the lead and yet allow passage of an elongate member that is slidably engaged within the lumen of the lead body, and
- a portion in which an agent is embedded, the agent adapted to disperse from the portion out through the outer surface.
