  • Patent number: 7081132
    Abstract: A barbed medical prosthesis is disclosed in which the barb includes a basal portion comprising a point of union with the substrate of origin (such as a strut), an anchoring portion adapted to embed into tissue, and a stress-dispersing portion located between the basal and anchoring portions. In one embodiment the stress-dispersing portion comprises a helical coil having a free winding that is unattached to the strut from which the barb extends. In another embodiment, the stress-dispersing portion comprises a series of bends or curves formed in the barb proximate to the point of union with the strut. The barb can be mechanically attached and/or soldered to the prosthesis, or integrally formed therefrom. A second barb portion and stress-dispersing portion, may also extend from the basal portion.

  • Patent number: 7077868
    Abstract: An attachment system secures a residual limb to an artificial limb in a comfortable and substantially non-rotational manner. The attachment system offers proximal anchoring of the residual limb in a hard socket, by connecting a side surface of a residual limb liner to the side surface of the socket. Preferably, this connection is accomplished using an extension member extending from the liner through a portion of the socket interior, through the socket wall, and attaching to a latch mechanism. The preferred attachment system requires no clearance in the bottom of the socket well because neither the extension member nor the latch mechanism is located between the distal end of the residual limb/liner and the bottom of the well. The attachment system is preferably disposed entirely along the side of the limb and the side of the socket.

  • Patent number: 6958076
    Abstract: A venous valve prosthesis includes a hollow conduit (40) defining a central passageway through which blood may flow. Opposing, pliable leaflet members (30) are located within the conduit and move back and forth between a first, open position, whereby blood may flow through the central passageway in a first direction, and a second, closed position, whereby blood is prevented from backflowing through the central passageway in a second direction which is opposite the first direction. A hollow and generally cylindrical support member (10, 20) retains the leaflet members and is coaxially disposed within the conduit. The support member includes opposing cutaway regions (18) defining two axially extending struts (16) supporting the leaflet members. The cutaway regions, in cooperation with the struts, allow the leaflet members to collapse inwardly to the closed position.

  • Patent number: 6935344
    Abstract: The present invention relates to systems and methods for performing beating heart surgery involving the step of maintaining at least partial blood flow through a protected blood flow path within the right and/or left side of the heart during surgery. The protected blood flow path may be established by positioning one or more conduits within at least a portion of the right and/or left sides(s) of the heart. In a first system, at least partial blood flow may be maintained through the protected blood flow path by the pumping action of a blood pump communicatively coupled to the conduit. In a second system, at least partial blood flow is maintained through the protected blood flow path by the pumping action of the beating heart itself. The systems are therefore capable of maintaining at least partial blood flow through the right and/or left side(s) of the heart, even during periods when the cardiac output becomes compromised.

  • Patent number: 6855164
    Abstract: This intraocular lens includes an optic body having anterior and posterior walls, a chamber, and optically transmissive primary and secondary fluids, and method for making and using the same. The secondary fluid is substantially immiscible with the primary fluid and has a different density and a different refractive index than the primary fluid. The primary fluid is present in a sufficient amount that orienting optical body optical axis horizontally for far vision positions the optical axis through the primary fluid, thereby immersing the anterior and posterior optical centers in the primary fluid. The secondary fluid is contained in the optic body in a sufficient amount that orienting the optical axis at a range of effective downward angles relative to the horizontal for near vision positions the optical axis to extend through the primary fluid and the secondary fluid, thus changing the focus of the intraocular lens.

  • Patent number: 6846325
    Abstract: A prosthetic heart value assembly comprising a prosthetic heart valve and a fixation band. The fixation band comprises a tubular frame and a tube. The tubular frame comprises longitudinally-extending members having hooks on their distal ends and fixation means on proximal ends, and a stabilizing laterally-extending member. The tube is positioned inside the longitudinally-extending members, a distal end of the tube being everted over the hooks. A sewing cuff is formed in the tube. The prosthetic valve is secured to the fixation band by suturing a prosthetic valve sewing cuff to a fixation band sewing cuff. The prosthetic valve and fixation band are advanced to the valve's seat. The fixation band's hooks are passed through the wall of the everted tube and into surrounding tissue and the fixation band's fixation means are deployed.

  • Patent number: 6821297
    Abstract: An artificial valve for repairing a damaged heart valve having a plurality of cusps separating upstream and downstream regions. The artificial valve includes a flexibly resilient frame with a plurality of peripheral anchors for anchoring the frame in position between the regions. The frame includes a central portion located between the anchors. The valve includes a flexible valve element attached to the central portion of the frame having an upstream side and a downstream side opposite the upstream side. The valve element moves to an open position when fluid pressure in the upstream region is greater than fluid pressure in the downstream region to permit downstream flow. The valve element moves to a closed position when fluid pressure in the downstream region is greater than fluid pressure in the upstream region to prevent flow reversal. The valve may be used in beating heart procedures, avoiding cardiopulmonary bypass and cardioplegia.
