Sensor, delivery system, and method of fixation
First Claim
1. An implant assembly for releasing into a vessel at an implant location having a diameter, the implant assembly comprising:
- an intracorporeal device comprising a longitudinal axis and a lateral axis, said longitudinal and lateral axes defining a plane; and
an anchor comprising a pair of resiliently deformable loops operatively associated with the intracorporeal device, both of said loops extending toward the same side of said plane;
wherein said deformable loops have a relaxed state and a deformed state;
wherein when said deformable loops are in a relaxed state, the implant assembly has a major dimension in a direction out of said plane that is greater than the diameter of a vessel at an implant location; and
wherein said loops are deformable so as to permit insertion of said implant assembly into said vessel, the tendency of said loops to return to their relaxed state exerting a force on a wall of said vessel that imposes said intracorporeal device against an opposite wall of said vessel.

Abstract
An implant assembly for releasing into a vessel at an implant location includes an intracorporeal device and an anchor. The anchor comprises a pair of resiliently deformable loops operatively associated with the intracorporeal device, both of the loops extending toward the same side of a plane defined by the intracorporeal device. The deformable loops have a relaxed state and a deformed state. When the deformable loops are in a relaxed state, the implant assembly has a major dimension in a direction out of the plane that is greater than the diameter of a vessel at the implant location. The loops are deformable to permit insertion of the implant assembly into the vessel. The tendency of the loops to return to their relaxed state exerts a force on a wall of the vessel that imposes the intracorporeal device against an opposite wall of the vessel.

13. A method of deploying and fixing an implant assembly in a vessel, comprising:
-
(a) mounting an implant assembly on a delivery apparatus, the implant assembly comprising an intracorporeal device and an anchor, the delivery apparatus comprising means for retaining the implant assembly on the catheter;
(b) placing a vessel introducer in an access site;
(c) placing the catheter and implant assembly into the vessel introducer;
(d) navigating the catheter to a deployment site, the deployment site having a diameter;
(e) actuating the implant assembly retaining means to disengage the implant assembly;
(f) removing the catheter from the body;
(g) allowing the anchor structure of the implant assembly to expand to hold the implant assembly against a wall of the vessel. - View Dependent Claims (14)
