Appl. No.:

09/773108

Inventors:

Tatyana Feldman - Newport Beach CA

Assignee:

Numed/Tech LLC - Newport Beach CA

International Classification:

A61F 606

US Classification:

128831, 128843, 604 1, 60438517

Abstract:

Disclosed are occluders and methods of their use. The occluders comprise shape-memory polymeric materials which, when heated above their crystalline melting temperatures, may be deformed from a first configuration into a second configuration. The occluder is then held in the deformed shape until it cools to a temperature below its crystalline melting temperature (T ) whereby it holds the deformed shape of the second configuration by virtue of the recrystallization of the polymeric occluder material. Upon reheating the occluder above its T , the occluder will resume its original shape. In this manner, an occluder which has been deformed to reduce its diameter may be inserted into and positioned within a target lumen in the body and then allowed to warm to body temperature whereby it resumes its original diameter and results in the occlusion of the lumen. The occluders, according to preferred embodiments, may be used for reversible sterilization of mammals, among other surgical and non-surgical uses.

International Classification:

F16D 33/00

US Classification:

416180, 416197 C, 60330

Abstract:

The present invention broadly comprises a cone connection assembly for a torque converter, including: a first surface operatively arranged for connection to a crankshaft and a second surface on a cover of the torque converter. The first and second surfaces are arranged to be engaged and the first surface is arranged to transfer torque to the second surface via the engagement of the first and second surfaces. In some aspects, the crankshaft comprises a longitudinal axis, the first surface is disposed about the longitudinal axis, the cover comprises an outside surface, and the outside surface comprises the second surface. In some aspects, the first and second surfaces are arranged to be frictionally engaged or the first and second surfaces have complementary surface features and the first and second surface features are arranged to interlockingly engage.

International Classification:

F16H 47/08

US Classification:

475 36, 475 53, 475 59

Abstract:

The present invention broadly comprises a torque converter including a cover and a planetary gear set rotationally interfaced with a hydraulic circuit and arranged to modify torque received by the cover from an engine. In some aspects, the gear set includes first and second components rotationally secured to the cover and an impeller shell, respectively. In some aspects, the first and second components are a carrier and ring gear, respectively. In some aspects, the gear set further comprises third and fourth component rotationally connected to a turbine shell and the output hub, respectively. The third component is arranged to receive torque from a clutch or a hub connected to the clutch. In some aspects, the third and fourth components are a carrier and ring gear, respectively. The gear set includes a component rotationally fixed with respect to a torque converter axis, and in some aspects, a ratchet one-way stator clutch.

Abstract:

A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

Abstract:

A prosthetic mitral valve system that comprises a valve dock and a prosthetic mitral valve is disclosed. The valve dock comprises clamp jaws that sandwich the native mitral valve leaflets and the native mitral valve annulus between them anchoring the prosthetic mitral valve system at or adjacent to the native mitral valve annulus. Further, a prosthetic mitral valve comprising atrial and ventricular clamp jaws and which can be implanted at or adjacent to the native mitral valve annulus without a valve dock system is disclosed. Novel methods and systems for treating mitral valve disease or malfunction by percutaneous replacement of the mitral valve (or the tricuspid valve) are disclosed.
