Abstract
An implantable sensor device, such as a pressure monitor, is implanted in the left ventricle (LV), in other heart chambers, or elsewhere, from which it wirelessly communicates pressure information to a remote communication device. The sensor device can be implanted using a placement catheter, an endoscope, or a laparoscope. The device can be secured entirely within the LV or heart wall, such as by using a corkscrew, a helical anchor, a harpoon, a threaded member, a hook, a barb, a fastener, a suture, or a mesh or coating for receiving fibrous tissue growth. The implantable sensor device provides less invasive chronic measurements of left ventricular blood pressure or other physical parameters. The wireless communication techniques include radio-telemetry, inductive coupling, passive transponders, and using the body as a conductor (referred to as “intracorporeal conductive communication” or a “personal area network”). Data from the receiver is downloadable into a computer for analysis or display.

76. A system for providing an implantable device into a patient'"'"'s body, the system comprising:
-
an implantable device having a pressure sensor; and
a placement catheter including a sheath having a proximal end, a distal end, and a cavity near the distal end in which to place at least a portion of the implantable device;
a plunger disposed in the sheath and configured to be releasably connected to the implantable device; and
a handle disposed near the proximal end of the sheath, the handle being coupled with the plunger to manipulate the plunger for moving the implantable device to transluminally deliver the implantable device into the patient'"'"'s body. - View Dependent Claims (77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89)

90. A method for transluminally delivering an implantable device into a patient'"'"'s heart, the method comprising:
-
providing a placement catheter including a sheath having a proximal end, a distal end, and a cavity near the distal end;
a plunger disposed in the sheath; and
a handle disposed near the proximal end of the sheath and coupled with the plunger inside the sheath;
placing the implantable device inside the cavity of the sheath, the implantable device having a pressure sensor;
releasably connecting the plunger to the implantable device in the cavity of the sheath;
delivering the placement catheter into the patient'"'"'s heart by inserting the distal end of the sheath transluminally into the patient; and
using the handle to manipulate the plunger for moving the implantable device to secure the implantable device to the patient'"'"'s heart. - View Dependent Claims (91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103)
