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.

Abstract
A method and apparatus for retaining a medical device within a blood vessel are described. A medical device (e.g. a pulse generator or a lead) is positioned within a blood vessel. An expandable the retention sleeve is passed into the vessel adjacent to the medical device and expanded to an expanded position to engage the medical device between an exterior surface of the retention sleeve and a surface of the vessel.

20. A system for retaining a medical device within a blood vessel, the system comprising:
-
a fluid impermeable vessel liner proportioned to be received with a vessel; a medical device positionable within the vessel liner, 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 medical device bends in response to passage of the pulse generator through curved regions of the vasculature; and an expandable retention device proportioned to be telescopically received within the vessel liner, the retention device expandable within the vessel liner into contact with the medical device to thereby retain the medical device between the retention device and the vessel liner. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

29. A method for providing a medical device and providing instructions for retaining the medical device within the vasculature of a patient, comprising:
-
providing a retention sleeve having a longitudinal length, the retention sleeve expandable from a compressed position to an expanded position; providing an elongated medical device, the medical device comprising a pulse generator having a generally cylindrical construction with a circular cross-section that forms a hermetically sealed housing containing circuitry and a battery, the medical device having a longitudinal length that is longer than the longitudinal length of the retention sleeve and being configured to be flexible about a longitudinal axis; and providing instructions to implant the medical device in the vasculature of the patient, including; positioning the medical device entirely within the vasculature of a patient, including bending 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 vasculature adjacent to a portion of 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 an interior surface of the vasculature.

30. A system for retaining a medical device within a blood vessel, the system comprising:
-
a fluid impermeable vessel liner proportioned to be received with a vessel; a medical device positionable within the vessel liner and having a generally cylindrical construction with a circular cross-section and a longitudinal length 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 medical device bends in response to passage of the pulse generator through curved regions of the vasculature; and an expandable retention device proportioned to be compressibly received within the vessel liner, the retention device having a longitudinal length that is less than the longitudinal length of the medical device, the retention device expandable within the vessel liner into contact with a portion of the medical device to thereby retain the medical device between the retention device and the vessel liner.
