International Classification:

A61B 17/04

US Classification:

606144000

Abstract:

A method and apparatus for repairing the heart's mitral valve by using anatomic restoration without the need to stop the heart, use a heart-lung machine or making incisions on the heart. The method involves inserting a leaflet clamp through the heart's papillary muscle from which the leaflet has been disconnected, clamping the leaflet's free end and then puncturing the leaflet. One end of a suture is then passed through the hollow portion of the clamp, while the other end of the suture is maintained external to the heart. The clamp is then removed and the suture's two ends are fastened together with a securement ring/locking cap assembly to the heart wall exterior, thereby reconnecting the leaflet to the corresponding papillary muscle. The introduction of the clamp, puncturing of the leaflet, passage of the suture therethrough and removal of the clamp can be conducted a plurality of times before each suture's two ends are fastened to the securement ring/locking cap assembly.

Abstract:

An electromagnetic bandgap structure comprising a progressive cascade of a plurality of patterns of cells. The cells of each pattern are dimensioned so that each pattern has a reflection phase response centered at a different, but closely-spaced, frequency compared with the reflection phase response of an adjacently positioned pattern, so that the combined reflection phase response of the plurality of patterns provides a continuous wideband operational range.

Abstract:

An identification band having a pocket portion and a strap portion extending from the pocket portion. The pocket portion encloses identification information pertaining to the wearer. The periphery of the pocket portion is configured to convey a creative artistic impression, that is, a configuration resembling at least a portion of any one of a living being (alive now or in the past), cartoon character, a man-made functional article (such a transportation vehicle and a building), a natural object (such as a cloud or star) and a decoration (such as holiday decorations and artwork). The pocket portion may be relatively planar or be formed so that the artistic impression is three-dimensional.

Cavitron Corporation - New York NY

International Classification:

A61M 100
G05D 1111

US Classification:

128276

Abstract:

A fluidic control system for use in irrigation and aspiration of the anterior chamber of the eye during ultrasonic emulsification of a cataract therein. The system comprises a handpiece with an (ultrasonically vibrated) hollow tip, the hollow tip being connected to the fluid withdrawal or aspirating portion, while an annular passage around the tip is used to introduce fluid for irrigation purposes. The aspirating portion comprises a withdrawal hose attached to the output manifold of the handpiece in fluid communication with the hollow tip, a constant flow pump attached to the other end of the withdrawal hose, and a vacuum relief valve connected to the withdrawal hose intermediate the pump and the handpiece. The irrigation portion comprises a fluid supply bottle at a predetermined height above the eye, and administration set attached to the bottle, and an inflow hose attached to the intake manifold of the handpiece and in fluid communication with the annular passage. All the aforementioned components are in fluid communication with the anterior chamber of the eye during removal of a cataract by insertion of the handpiece tip into the eye chamber.
