DELIVERY STYSTEM FOR AN IMPLANTABLE PHYSIOLOGIC SENSOR
First Claim
1. A system for deploying an implantable sensor assembly at an implantation site in a patient, the sensor assembly including a sensor element and an anchor, the system comprising:
- an outer catheter;
an elongate, tubular first inner member movable within the outer catheter and having a distal end portion terminating in a distal opening, the distal end portion sized to receive at least a portion of the sensor assembly for delivery of the sensor assembly to the implantation site; and
a retaining element slidably disposed within the first inner member, the retaining element including;
an elongate body having a distal end;
a sensor engagement structure on the distal end of the body adapted to releasably engage the sensor assembly; and
an actuating member slidably coupled to the body and adapted to cause the sensor engagement structure to engage the sensor.

Abstract
A delivery system for deploying an implantable sensor assembly at an implantation site in a patient, the sensor assembly including a sensor element and an anchor. The delivery system includes an outer catheter, an elongate, tubular first inner member movable within the outer catheter, and a retaining element disposed within the first inner member and adapted to releasably engage the sensor assembly during delivery. In one embodiment, the first inner member has a distal end portion including a sheath sized to receive the sensor assembly and retain the anchor in a collapsed delivery configuration. In another embodiment, the first inner member includes a distal end portion including a socket sized to releasably retain a portion of the sensor during delivery.

17. A method of implanting an implantable sensor assembly at an implantation location in a vasculature system of a patient, the sensor assembly including a sensor and a self-expanding anchor, the method comprising:
-
transvenously advancing a catheter into the vasculature system such that a distal end of the catheter is positioned proximate the implantation location;
advancing the sensor assembly through a lumen of the catheter to the implantation location, the sensor assembly releasably retained at a distal end of a delivery device including;
an elongate, tubular first inner member movable within the catheter and having a distal end portion terminating in a distal opening, the distal end portion sized to receive at least a portion of the sensor assembly for delivery of the sensor assembly to the implantation site; and
an elongate retaining element disposed within the first inner member;
deploying the sensor assembly from the distal opening of the first inner member with the retaining element releasably coupled to the sensor assembly; and
de-coupling the retaining element from the sensor assembly. - View Dependent Claims (18, 19, 20, 21)
