摘要： A delivery device for implanting a medical device that includes an expandable fixation member adapted to fix the position of the medical device within a lumen of a human body. The delivery device has an inner shaft rotatably disposed in a tubular outer shaft. A retention member is secured to and rotatable with the inner shaft and has a free end and a retainer portion adapted to protrude outwardly through an exit aperture in the outer shaft to extend circumferentially about the exterior of the outer shaft. The fixation member of the medical device may be retained on the tubular shaft in a low profile configuration by the outwardly protruding retainer portion and may be released to expand upon retraction of the retainer portion in response to rotation of the inner shaft.

摘要： An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation member that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation member may be configured to lie in a single plane when deployed or may be tubular in shape. The attachment of the housing and fixation member includes providing the fixation member with a linear attachment strut that is non-circular in cross section and providing the housing with external members that define an elongate channel, non-circular in cross section and receptive to the attachment strut. The attachment strut can be inserted transversely into the channel and the external member can be crimped over the strut to secure the housing and fixation member together.
