Abstract: The present invention is a method of practicing transcatheter valve replacement (TAVR) employing an expandable hollow mesh-like catheter which may be inserted through an aorta to the proximity of a diseased or degenerated aortic valve in a retracted form and then expanded to compress the valve to open it up. Subsequently a new valve will be placed on the collapsed mesh, will be fed through the aorta, and the mesh will be expanded to push the leaflets of the old valve aside. The mesh does not block blood flow, eliminating the need to instigate a rapid heartbeat as required in the prior art procedure employing a balloon rather than the mesh.

Abstract: An intrusion detector system employing a remote, 360.degree. infrared detector. The system includes a base unit with a receiver, controller, and phone jack, a remote sensor which is adjustable along a vertical axis and includes a 360.degree. infrared motion sensor, and a central monitoring station in communication with the base unit via a telephone network. The remote sensor may be selectively positioned to detect movement in a surrounding area definable by the user. The base unit may be programmed to contact the monitoring station when the sensor detects motion, and also to receive test signals from the monitoring station and verify that the system is operational.

Abstract: An intrusion detector employing a remote, 360.degree. infrared detector. The detector includes a base unit with a receiver, controller, digital dialer and power supply plug, a remote sensor which is adjustable along a vertical axis and includes a 360.degree. infrared motion sensor, and a hand held remote control unit to arm and disarm the base unit. The remote sensor may be selectively positioned to detect movement in a surrounding area definable by the user.
