International Classification:

A61B 1900

US Classification:

128898, 623 211, 623902

Abstract:

A method for deploying an aortic valve prosthesis includes the steps of: making a first opening leading to the left atrium; passing the 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 cardiac chamber; securing the second manipulation instrument to the valve prosthesis; and using the second manipulation instrument to retract at least a portion of the valve prosthesis out of the cardiac chamber.

US Classification:

623 237, 623903, 623904

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.

US Classification:

623002110, 623904000

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.

Daniel Edward Taylor - Monroe OH, US

International Classification:

B29C 67/00
B29C 49/00

US Classification:

264440, 425 90, 425100, 425103, 425532

Abstract:

An apparatus and method for producing plastic objects. The apparatus comprises an extruder disposed to extrude at least one parison, a parison coating system and a mold disposed to receive the extruded parison. The parison coating system comprises: a powdered material source; a fluid source interconnected with the powdered material source; and a nozzle connected to the interconnected fluid and powdered material sources. The nozzle is disposed such that the nozzle disperses the powdered material in a spray pattern which interacts with the extruded parison. The method comprises steps of extruding a plastic parison, applying a powdered material coating to the parison, enclosing the coated parison in a mold cavity and expanding the coated parison to the limits of the cavity.

US Classification:

623 211

Abstract:

Methods for replacing native valve function of a diseased aortic valve are disclosed. In an embodiment, a method for replacing native valve function of a diseased aortic valve in a patient includes: (a) receiving an artificial heart valve assembly mounted about a first mounting position on a catheter system, (b) guiding the artificial heart valve assembly through the vasculature of the patient, (c) while the catheter system having the artificial heart valve assembly mounted thereto is in the patient's vasculature, mounting the artificial heart valve assembly about a second mounting position on the catheter system, (d) delivering the artificial heart valve assembly to the region of the diseased aortic valve, (e) expanding the artificial heart valve assembly in the region of the diseased aortic valve, and (f) withdrawing the catheter system from the patient's vasculature.
