    摘要： A thoracic cavity drainage device includes a first vessel having a plurality of chambers one of which is a regulated drainage chamber, and a separate transfer vessel which receives fluid collected in the drainage chamber of the first vessel. The chambers of both vessels are interconnected in a series by fluid passageways which cooperate to maintain a uniform range of suction in the drainage chamber while preventing passage of water into the drainage chamber and permitting a different level of suction in the transfer vessel. This operation is effective despite relatively large pressure and vacuum impulses caused by stripping of drainage lines, patient coughing, and the like, and despite discrete changes in the physical configuration of the system caused by disconnection of the transfer vessel, connection of the transfer vessel to an infusion line or the opening or closing of fluid lines and ports. A novel transfer vessel empties the drainage device and provides gravity reinfusion of the collected fluids. A mechanism within the transfer vessel provides an effective suction without vacuum connections or pressure regulating adjustments.

    摘要： Disclosed are the product and method for making a macroscopically smooth, microporous, flexible, elastic tubular prosthetic device from a substantially non-elastic woven fabric tube. The method involves axially compressing the substantially non-elastic tube on a tight fitting cylindrical mandrel so that the individual axially oriented threads of the fabric form loops projecting radially outwardly between circumferential threads. The threads are set to return to this loop configuration upon release of tension applied axially to the tube. The exterior of the tube presents an easily deformed, macroscopically smooth surface having a multiplicity of interstices among the threads and among the fibers of the threads into which cells can grow after implantation.

    摘要： Disclosed is a method of producing implantable prosthetic devices, e.g., tubular vascular prostheses having a substantially non-thrombogenic inside surface and a biocompatible outside surface. The method involves deposition onto an elongate substrate, e.g., a porous tubular substrate, of a fluorine-containing coating by inducing glow discharge progressively along the length of a tubular reaction vessel. A polymerizable fluorine-containing gas is flowed through the tubular substrate and a portion of the gas migrates radially to traverse the pores of the substrate. An RF field is applied to successive volumes of the gas within the vessel and tube. A substantially non-thrombogenic fluorinated coating with a first fluorine to carbon ratio deposits and bonds to the inside surface of the substrate, and a fluorinated biocompatible cross-linked coating with a lower F/C atomic ratio than the inside coating deposits and bonds to the outside surface of the substrate. The method of the invention can produce uniform coatings containing fluorine over the surface of elongated substrates. The coatings can be engineered to have a very low surface energy and to be essentially non-thrombogenic.

    摘要： A stent device is provided. The stent device includes: at least one radially expandable body portion extending along a longitudinal axis of the stent device defining a lumen; and at least one outwardly flarable portion connected to the body portion. The outwardly flarable portion includes at least one radially expandable ring connected to the body portion and at least one flaring connector connected to the at least one ring configured to cause a crown of the at least one ring to automatically flare radially outwardly relative to other portions of the ring upon radial expansion of the body portion so as to form a flared crown. After radial expansion, the outwardly flaring portion may be held in place by a support strut that lessens its ability to collapse. A method of deploying the stent device is also provided.

    摘要： A deployment device for a flexible implant includes a housing and one or two chambers formed therein. When two chambers are included, the housing can have two elongate openings formed in its outer sides, each providing side access to one of the chambers, and the flexible implant can be rolled into a double-rolled configuration and placed in the chambers of the deployment device in such a way that a middle portion of the flexible implant is external to the housing. When the flexible implant is rolled and loaded in the deployment device, the flexible implant can extend out through open end(s) of the chamber(s) or can be encapsulated within the chamber(s). The flexible implant can be provided separate from the deployment device. The flexible implant can include a flexible base sheet including a body portion and a tab. A flexible separable layer can be removably disposed on the body portion.
