A prosthetic heart valve having spaced apart anchoring flanges that change shape when the valve is implanted and contact the surrounding annulus to prevent migration of the valve. The heart valve may be non-expandable and the anchoring flanges may provide the primary anchoring structure of the valve. Alternatively, the valve may be expandable wherein the anchoring flanges supplement the inherent anchoring capacity of the valve structure. The anchoring flanges are at least partly made of a material that increases in size, i.e., swells, due to absorption of body fluids. For instance, the anchoring flanges may be formed of an inner material that swells upon contact with body fluids enclosed by a cover. The anchoring flanges may be provided on an anchoring sleeve that changes shape to provide the spaced apart annular flanges for securing the valve around a fibrous annulus. An anchoring sleeve for a prosthetic heart valve having an expandable frame surrounds a majority of the frame and may define an external hourglass configuration.

A composition including lecithin which is useful for defoaming liquids, such as blood. In one aspect of the invention the composition includes inorganic particles. In another aspect of the invention the composition includes a silicone.

Antifoam compositions including lecithin and uses thereof

A deformable intraocular lens injecting apparatus for inserting a deformable intraocular lens through a small incision into an eye. The apparatus includes a lens injecting body including a lens receiver configured to be operated between an open configuration and a closed configuration, and a nozzle portion provided with a tip portion configured to be inserted through a small incision into an eye. The nozzle portion is configured for connection to the lens receiver of the lens injecting body, and the nozzle portion and the lens receiver defining a lens delivery passageway. A plunger is slidably disposed relative to the lens delivery passageway and configured to engage a deformable intraocular lens within the lens delivery passageway of the lens receiver, and to move the deformable intraocular lens out of the lens delivery passageway into the eye.
