Abstract: A method for reducing mitral regurgitation includes deploying deforming matter into a selected one of (i) a mitral valve annulus adjacent a posterior leaflet, and (ii) tissue adjacent the mitral valve annulus and proximate the posterior leaflet, to cause conformational change in the mitral valve annulus to increase mitral valve leaflet coaptation.

Abstract: A method and apparatus for reducing mitral regurgitation. The apparatus is inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the apparatus being adapted to straighten the natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, whereby to move the posterior annulus anteriorly and thereby improve leaflet coaptation and reduce mitral regurgitation.

Abstract: Apparatus for reducing mitral regurgitation, by applying a force to the wall of the coronary sinus so as to force the posterior leaflet anteriorly and thereby reduce mitral regurgitation.

Abstract: Apparatus for reducing mitral regurgitation, including a bendable elongated body adapted to be inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the elongated body being adjustable between a first configuration adapted to be delivered into the coronary sinus and a second configuration adapted to exert a force onto the posterior annulus. The body includes a flexible spine having a proximal end and a distal end, and a flexible wire mounted on the spine and having a distal end fixed to the spine proximate to the distal end of the spine, and having a proximal portion extending from the proximal end of the spine. Axial movement of the wire causes a change in the spine from the first configuration to the second configuration to exert the force on the posterior annulus and thereby reduce mitral regurgitation.

Abstract: The present invention comprises a method for deploying an aortic valve prosthesis. This valve prosthesis may include any of the known aortic valves including, but not limited to, stented and unstented bioprosthetic valves, stented mechanical valves, and expandable or self-expanding valves, whether biological or artificial. The method involves the steps of: making a first opening leading to the left atrium; passing a valve prosthesis through the opening and into a cardiac chamber of the left side of the heart using a first manipulation instrument; making a second opening in the arterial system and advancing one end of a second manipulation instrument through the arterial opening and into the aforementioned cardiac chamber; securing the second manipulation instrument to the valve prosthesis; and using the second manipulation instrument to retract at least some portion of the valve prosthesis out of the aforementioned cardiac chamber.

Abstract: The present invention provides catheter apparatus and catheterization methodology for generating an arteriovenous fistula or a veno-venous fistula on-demand between closely associated blood vessels and at a chosen anatomic site in-vivo. The catheter apparatus is preferably employed in pairs, each catheter of the pair being suitable for percutaneous introduction into and extension through a blood vessel. The catheterization methodology employs the catheter apparatus preferably in conjunction with conventional radiological techniques in order to place, verify, and confirm a proper alignment, orientation, and positioning for the catheters in-vivo prior to activating the perforation means for generating a fistula.

Abstract: The present invention relates to a device and method for warming biological fluids. The portable self-contained device which warms physiological fluids including blood is comprised of a reaction container which is capable of storing at least one chemical which when mixed with a second chemical will produce an exothermic chemical reaction, a mixing means for mixing the two chemicals to produce the exothermic chemical reaction, a heat exchanger to absorb heat from the exothermic reaction and transfer it to the physiological fluid or blood, a temperature regulating means to regulate the maximum temperature of the device and an insulating container for enclosing the reaction means, heat exchanger and temperature regulating means. The method of rapidly heating the stored cold physiological fluids including blood to about 39.degree.

Abstract: A video security system with intercom activated by means of a doorbell. The video input to a remote camera is automatically presented on the video display of a television receiver upon activation of the doorbell while audio from the intercom's speaker microphone is output through the television receiver's speaker system. Following a predetermined time interval after doorbell actuation, the system automatically turns off. If the television receiver is on when the doorbell is actuated, the system automatically provides video camera and intercom information at the television, reverting to the received television signal mode of operation upon user selection.

Abstract: An electronic switch is provided for use in a battery-powered portable television receiver which eliminates power supply current drain when the television receiver is turned off. Coupled transistors are rendered conductive by means of either a clock or a manually switched input signal to provide a direct voltage battery output to television receiver circuitry. Also disclosed in an electronic switch combination for selectively controlling the audio output for the entire television receiver either manually or automatically.
