摘要： In accordance with the present invention there is provided a delivery apparatus for a self-expanding stent. The apparatus has an outer sheath which is an elongated tubular member with distal and proximal ends and inside and outside diameters. The outer sheath has an enlarged section adjacent its distal end. The enlarged section has a greater inside and outside diameter than the inside and outside diameter of the sheath proximal to the enlarged section. The apparatus also includes an inner shaft located coaxially within the outer sheath. The shaft has a distal end and a proximal end. The shaft further includes a stop attached thereto which is proximal to the distal end of the sheath. Lastly, the apparatus includes a self-expanding stent located within the enlarged section of the outer sheath and makes frictional contact with the outer sheath. The shaft is disposed coaxially within a lumen of the stent, whereby the stent makes contact with the stop during deployment.

摘要： Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned.

摘要： A stent or other intraluminal medical device having markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. The housings are formed integral to the stent and the marker inserts are made from a material close in the galvanic series to the stent material and sized to substantially minimize the effect of galvanic corrosion.

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.
