摘要： A stent-graft for insertion into a body lumen, such as a blood vessel, is utilized in order to repair such lumen. The stent-graft includes a substantially cylindrical hollow expandable stent comprising a plurality of interconnected struts. The stent has a distal end and a proximal end, and an interior surface and an exterior surface. At least one strut of the stent has first and second apertures extending therethrough from the interior surface to the exterior surface. The stent-graft also includes a graft member covering a predetermined portion of least one of the interior surface and the exterior surface of the stent. In addition, the stent-graft further includes a staple for attaching the graft member to the stent. The staple has a crown and two legs extending therefrom. At least one of the legs of the staple extends through the graft material and through the first aperture. Both of the legs are bent inwardly towards said crown such that they evert back and extend through the second aperture.

摘要： An elastomeric valve partition is conventionally mounted on a catheter comprising a tubular catheter body. The valve partition defines a central aperture extending inwardly from one of the faces, only partway through the valve partition. The partition also carries a plurality of radial slits extending from the other of the faces only partway through the valve partition and intersecting the central aperture. The central aperture is of a diameter to closely fit a guidewire extending through the valve partition, while the radial slits have a length that is at least double the radius of the central aperture. The slits preferably rotate circumferentially about 5 to 60 degrees as they extend through the valve partition from one face toward the other. A lubricity enhancing additive is present, selected from the group consisting of bismuth oxychloride, polytetrafluoroethylene, titanium dioxide, graphite, polyethylene wax, polyvinylpyrrolidone, and combinations thereof.

摘要： A catheter which carries a hemostasis valve, such as a catheter sheath introducer, carries a slit elastic valve partition as part of the hemostasis valve. The inner housing has a bore and the end cap has an aperture that each communicate with an opposed surface of the valve partition. The diameter of the aperture and the bore are each of a distance that exceeds the outer diameter of preferably a french six catheter extending through the catheter of this invention, plus two times the thickness of the partition. When these conditions are satisfied, larger diameter inner catheters can be slidably inserted and removed through the catheter and valve of this invention with reduced frictional characteristics. Also, a compression ring is provided between the valve partition and the end cap which causes the valve partition to bow outwardly against the end cap and toward the aperture thereof. This, in turn improves the sealing characteristics. Also, an improved slit design for the partition is disclosed.

摘要： The invention describes an apparatus and method of use for anchoring two or more body tissue layers to one another. The apparatus includes a plurality of individual anchor segments that are placeable within a body cavity. The segments may assume a first relaxed state wherein the segments are movable relative to each other and alignable along an initial longitudinal axis for initial placement of the apparatus through the body tissue layers. Once placed within the body cavity, the anchor segments are manipulated into a second rigid state with an actuator wherein the segments assume a rigid configuration at a transverse angle relative to the initial longitudinal axis.

摘要： A delivery apparatus for a self-expanding stent is disclosed. The apparatus has an outer sheath forming an elongated tubular member having distal and proximal ends and an inside and outside diameter. The apparatus also includes an inner shaft located coaxially within the outer sheath. The inner shaft has a distal end, a proximal end and longitudinal axis extending therebetween. At least a portion of the inner shaft is made from a flexible coiled member. The shaft preferably includes a stop attached thereto, the stop being proximal to the distal end of the sheath. Lastly, the apparatus includes a self-expanding stent located within the outer sheath, wherein the stent makes frictional contact with the outer sheath and the shaft is disposed coaxially within a lumen of the stent. During deployment of the stent, the stent makes contact with the stop.

摘要： During root canal procedures, pulp may be removed from a tooth without disturbing the dentin by directing pulses of a heated liquid onto the pulp at particular temperatures and pressures to liquefy or gellify the pulp. The liquefied or gellified material is then aspirated away using the methods and apparatuses described herein. In some embodiments the heated liquid also functions to kill bacteria that may be present within the tooth.

摘要： Visceral fat may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered in pulses, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the visceral fat to soften, liquefy, or gellify, without damaging the subject's internal organs that are in the vicinity of the visceral fat. The visceral fat that has been softened, liquefied, or gellified is then suctioned away.
