An apparatus for releasably engaging an implantable medical device during delivery includes an elongate, tubular body having an open distal end a plurality of deflectable jaw members extending distally from the distal end of the body and terminating in distal tip portions, and an actuating member slidably disposed within the body and including a distal end portion operable to prevent inward deflection of the jaw members when positioned proximate the distal tip portions. The jaw members are adapted to releasably engage an engagement feature of the implantable medical device.

1. An apparatus for releasably engaging an implantable medical device, the apparatus comprising: a tubular body having an open distal end;a plurality of deflectable jaw members coupled to the distal end of the body and extending distally from the distal end of the body and terminating in distal tip portions, the jaw members adapted to releasably engage the implantable medical device; andan actuating member slidably disposed within the body and including a distal end portion configured to deflect the plurality of deflectable jaw members. 2. The apparatus of claim 1, wherein the actuating member is movable within the body and dimensioned to extend distally beyond the distal tip portions of the plurality of jaw members. 3. The apparatus of claim 1, wherein the plurality of deflectable jaw members are configured to releasably engage the implantable medical device by frictionally engaging the inner surface of the aperture of the implantable medical device. 4. The apparatus of claim 1, wherein the actuating member is configured to prevent inward deflection of the jaw members when positioned proximate the distal tip portions. 5. The apparatus of claim 4, wherein the plurality of deflectable jaw members are biased inwardly with respect to the distal end of the body. 6. The apparatus of claim 5, the distal end portion of the actuating member is further configured to force the plurality of jaw members outwardly when positioned proximate the distal tip portions. 7. The apparatus of claim 1, wherein the plurality of jaw members are biased inwardly. 8. The apparatus of claim 7, wherein the plurality of deflectable jaw members deflect in response to movement of the actuating member proximate to the distal end portion. 9. The apparatus of claim 1, wherein the tubular body is made from a material selected from the group consisting of stainless steel, shape memory polymers, and shape memory alloy, and the plurality of jaw members are made from Nitinol. 10. A system comprising: an elongate catheter having an inner lumen;an implantable medical device sized to be slidably received within the lumen, the implantable medical device having a proximal portion including an engagement feature; anda retaining element movable within the lumen and including: a tubular body having an open distal end;a plurality of deflectable jaw members coupled to the distal end of the body and extending distally from the distal end of the body and terminating in distal tip portions, the jaw members adapted to releasably engage the implantable medical device; andan actuating member slidably disposed within the body and including a distal end portion configured to deflect the plurality of deflectable jaw members. 11. The apparatus of claim 10, wherein the implantable medical device comprises an engagement feature, and the plurality of deflectable jaw members are configured to releasably engage the engagement feature of the implantable medical device. 12. The apparatus of claim 11, wherein the implantable medical device comprises an anchor. 13. The apparatus of claim 12, wherein the retaining element is configured to retract the implantable medical device, including the anchor, within the inner lumen in response to pulling proximally on the retaining element. 14. The apparatus of claim 11, wherein the engagement feature includes an aperture sized to at least partially receive the jaw members and having an inner surface, and wherein the jaw members are adapted to frictionally engage the inner surface. 15. The apparatus of claim 10, wherein the implantable device is a sensor configured to sense at least one of blood pressure, temperature, blood or fluid flow, strain, electrical, chemical, and magnetic properties within a patient's body. 16. The apparatus of claim 10, wherein the implantable device is configured to store and transmit blood pressure data. 17. The apparatus of claim 16, further comprising another implantable device, and the first recited implantable device is configured to store and transmit blood pressure data to the other implantable device. 18. An apparatus comprising: a tubular body having an open distal end;a plurality of deflectable jaw members coupled to the distal end of the body and extending distally from the distal end of the body and terminating in distal tip portions, the jaw members adapted to releasably engage an implantable medical device; andan actuating member slidably disposed within the body and including a distal end portion configured to deflect the plurality of deflectable jaw members in response to movement of the actuating member proximate to the distal end portion. 19. The apparatus of claim 18, wherein the implantable medical device comprises an engagement feature, and the plurality of deflectable jaw members are configured to releasably engage the engagement feature of the implantable medical device.
