Title:
IMPLANTABLE SENSOR WITH WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO2000016686
Kind Code:
A3
Abstract:
An implantable sensor device (105), such as a pressure monitor, is implanted in the left ventricle (LV) (135), in other heart chambers, or elsewhere, from which it wirelessly communicates pressure information to a remote communication device (140). The sensor device can be implanted using a placement catheter (600), an endoscope, or a laparoscope. The device can be secured entirely within the LV or heart wall, such as by using a corkscrew (312A), a helical anchor, a harpoon (312B), a threaded member, a hook, a barb, a fastener, a suture, or a mesh (312C) or coating for receiving fibrous tissue growth. The implantable sensor device (105) 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.
