Abstract: An electrode assembly for an elongated implantable lead containing conducting filars. The electrode assembly has a first support hull surrounding a portion of the lead. The electrode assembly also has an electrode hull for at least partially surrounding the support hull and a portion of the lead adjacent to the support hull. The electrode hull secures to the support hull and to the lead at a location axially spaced from the support hull, such that the electrode hull, the support hull, and the lead define a gap. The gap allows the conducting filars to operatively connect to the first support hull.

Abstract: A cardiac lead is disclosed which includes an elongated lead body having opposed proximal and distal ends, a tip electrode operatively associated with the distal end of the elongated lead body, a connector operatively associated with the proximal end of the elongated lead body and electrically connected to the tip electrode, and a cylindrical eluting ring disposed proximate the tip electrode and formed from a compound including an elastomer and about 15% to 25% by weight medicament.

Abstract: A permanent implantable lead having an elongated lead body with a proximal end and a distal end. A multifilar conductor having electrically active elements for providing electrical communication between connectors at the proximal end and electrical components between the proximal and distal ends of the lead body, wherein hulls facilitate resilient, low profile, efficient connection between the multifilar conductor and electrical components and seals secure the position of the electrical components. The hulls are located radially outward of the conductor and radially inward of the electrical components and the seals are located radially outward of the electrical components.
