Abstract: An apparatus includes a coupling portion, a bioerodible anchor portion and a bioerodable retainer. The coupling portion is configured to be coupled to an electrical conductor. The bioerodible retention portion is adjacent to the coupling portion and is moveable from a collapsed configuration to an expanded configuration. The bioerodible retention portion is configured to anchor the electrical conductor with respect to body tissue when the bioerodible retention portion is in its expanded configuration. The bioerodible anchor portion is formulated to erode when disposed within the body tissue at a first rate. The bioerodible retainer is coupled to the bioerodible anchor portion and is configured to inhibit movement of the bioerodible anchor portion from the collapsed configuration to the expanded configuration. The bioerodible retainer is formulated to erode when disposed within the body tissue at a second rate greater than the first rate.

Abstract: An apparatus includes an elongate member having a proximal end portion and a distal end portion. The proximal end portion is configured to receive an electrical current from a current source. The elongate member is configured to transmit the electrical current from the proximal end portion to the distal end portion. At least a portion of the elongate member is configured to be disposed within a body of a patient. An electrode is coupled to the distal end portion of the elongate member. The electrode is configured to transmit a portion of the electrical current from the distal end portion of the elongate member to a target bodily tissue. A coating is disposed on at least a portion of the elongate member. The coating is formulated to release at least one of a therapeutic agent, a conductive agent, and/or an insulative agent into the body of the patient in response to the electrical current being transmitted from the proximal end portion to the distal end portion of the elongate member.
