A61F 1100

US Classification:

606108, 623 112

Abstract:

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.

US Classification:

604525, 623 111, 606108

Abstract:

A delivery apparatus for self-expanding stents may be utilized to safely deliver stents to a target site. 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 a 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.

US Classification:

427 224, 4274071

Abstract:

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.

International Classification:

A61F 2/06

US Classification:

623 116, 623 115

Abstract:

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.

International Classification:

A61M 2900

US Classification:

604 96

Abstract:

A balloon dilatation catheter is provided which has a stiff proximal cannula made of a material such as metal hypotubing. The distal end of the catheter includes an inflatable medical device balloon, an inflation lumen and a guidewire lumen. A coiled transition assembly is positioned between the proximal cannula and the distal end section. This coiled transition assembly has a tightly wound coil within a tube and provides for a flexible transition between the two components of diverse stiffness, namely the proximal cannula and the flexible distal end portion. The dilatation catheter typically has an easily or rapidly exchangeable feature and is used in conjunction with a guiding catheter. During a procedure when the catheters are within the vascular system, the coiled transition section of the dilatation catheter readily follows tightly curved portions of the inserted guiding catheterby.

Abstract:

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.
