Abstract:
1. A method for retaining a medical device within a blood vessel, comprising: providing a retention sleeve, the retention sleeve expandable from a compressed position to an expanded position; introducing a medical device into a blood vessel, wherein the medical device comprises an elongated pulse generator having a generally cylindrical construction with a circular cross-section that forms a hermetically sealed housing containing circuitry and a battery, the elongated pulse generator being configured to be flexible about a longitudinal axis such that the step of introducing the medical device includes bending of the pulse generator in response to passage of the device through curved regions of the vasculature; with the retention sleeve in the compressed position, positioning the retention sleeve in the vessel adjacent to the medical device; and expanding the retention sleeve to the expanded position to engage the medical device between an exterior surface of the retention sleeve and a surface of the vessel.
