Method and apparatus for delivering an implantable wireless sensor for in vivo pressure measurement
First Claim
1. An apparatus for implanting into a patient an implant device having a corkscrew-type anchor associated therewith, comprising:
- an elongated, flexible shaft having proximal and distal ends;
a retention mechanism disposed at the distal end of said shaft for retaining said device at the distal end of said catheter; and
means selectively operable for disengaging said retention mechanism from said implant device when said anchor has been anchored into tissue at a target site.

Abstract
An apparatus for implanting an implant device having a corkscrew-type anchor associated therewith into a patient includes an elongated, flexible shaft. A retention mechanism is located at the distal end of the shaft for retaining the device at the distal end of the shaft. The apparatus includes means selectively operable for disengaging the retention mechanism from the implant device when the anchor has been anchored into tissue at a target site. In another aspect, an apparatus for releasing an implant into a vessel within a patient includes an elongated shaft for inserting into the vessel of the patient. A tether wire extends through the proximal portion of a secondary lumen, exits a first port, engages a portion of the implant, enters a second port, and extends through at least a portion of a distal portion of the secondary lumen. The implant is thereby tethered to the side of the elongated shaft, and pulling the tether wire disengages the tether wire from the distal portion of the secondary lumen and the implant so as to release the implant from the shaft.

13. An apparatus for releasing an implant into a vessel within a patient, comprising:
-
an elongated shaft for inserting into a vessel of a patient, said shaft defining a central lumen, a secondary lumen comprising proximal and distal sections, a first port for placing the proximal section of said secondary lumen in communication with the ambient surrounding said shaft, and a second port for placing the distal section of said secondary lumen in communication with the ambient surrounding said shaft;
a tether wire extending through the proximal portion of said secondary lumen, exiting said first port, engaging a portion of said implant, entering said second port, and extending through at least a portion of said distal portion of said secondary lumen;
whereby said implant is tethered to the side of the elongated shaft; and
whereby pulling said tether wire disengages said tether wire from said distal portion of said secondary lumen and said implant so as to release said implant from said shaft. - View Dependent Claims (14, 15, 16)
