    摘要： An expandable prosthesis includes a self-expanding stent deployable between a substantially radially compressed configuration and a substantially radially expanded configuration. A biocompatible coating is attached to at least a portion of the outer surface of the self-expanding stent in the radially compressed configuration to inhibit radially expansion of the self-expanding stent to the radially expanded configuration. The biocompatible material is preferably integrally mounted to the self-expanding stent thus eliminating the need for a separate, independent delivery tube or sheath for maintaining the self-expanding stent in the radially compressed configuration during delivery of the self-expanding stent into a body vessel.

    摘要： A radially expandable support body is enveloped within a cocoon. In a preferred construction, the support is a stent, and a tube of polymeric material, e.g., polytetraeluoroethylene (PTFE), passes through the interior of the stent body and is turned back upon itself over the stent to form a cuff. The assembly is then heated and the outer layer contacts and coalesces with the inner layer, closely surrounding the stent body within a folded envelope having a continuous and seamless end. In one embodiment, an end portion of the tube is expanded before folding back over the-stent. The end portion, which becomes an exterior surface of the finished product, thus acquires a greater degree of porosity. Each end of the central tube may be so expanded, and folded back to seal all surfaces and both ends. The stent body itself may be a ring, or a short series of spaced-apart rings, or a wire or web, or a sheet possessing a number of apertures extending entirely through the sheet. The spaces or apertures are covered over or bridged by both the inner and outer polymer layers. The apertures, which may comprise under five to over eighty percent of the surface area of the stent, constitute regions or a grid of points through which the material is coalesced and continuously bonded, and around which strain is distributed by the support. These points or regions remain tacked together so expansion of the assembly does not delaminate the polymer or create flaps and pockets. In another embodiment, a two tube construction is cuffed and assembled into a similarly unitized and seamless stent. One tube is cuffed back, and the other tube covers the cuffed stent. In this embodiment both the tube thicknesses and porosities may differ substantially. For example the inner porosity may be selected to enhance blood flow or intimal regeneration, and the outer surface may have a porosity to encourage anchoring to external muscle tissue.

    摘要： A chest drainage system includes a collection device and a fluid pathway configured to extend from the collection device to a patient. The fluid pathway has a proximal portion configured to extend proximally toward the patient and a distal portion configured to extend distally from the patient. The chest drainage system also includes a pressure source including an accumulator configured to selectively provide sub-atmospheric pressure to the distal portion of the fluid pathway and a valve configured to selectively relieve pressure in the proximal portion of the fluid pathway. The system is configured to open the valve and to introduce the sub-atmospheric pressure from the accumulator of the pressure source when a predetermined pressure differential is detected between the proximal and distal portions of the fluid pathway.
