摘要： A valve prosthesis, such as an artificial venous valve, is described. The valve prosthesis has a support frame formed from a cannula and an attached covering that defines an opening adapted to move between a first position in which the opening is open to fluid flow and a second position in which the opening is closed to fluid flow. The support frame includes a leaflet support portion and a circumferential centering support element disposed adjacent the leaflet support portion with respect to a lengthwise axis of the support frame and mirroring the leaflet support portion with respect to a transverse axis of the support frame.

摘要： A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

摘要： An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft wit with coupling portion disposed in the fenestration of the fenestrated stent graft.

摘要： Described, in certain aspects of the invention, are apparatuses and methods for deploying artificial devices within the vascular system. One apparatus includes a delivery device having a lumen and a deployment member slidably received within the lumen. This apparatus further includes an artificial device having an anchoring element releasably engaged with the deployment member. Such an apparatus can be percutaneously delivered to a site within a vascular vessel, and thereafter manipulated so that the anchoring element attaches to the vessel wall. The delivery device and deployment member can then be withdrawn from the vessel, whereby the deployment member disengages from the anchoring element, leaving the artificial device implanted in the vessel.

摘要： A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with one or more dilation elements that extend along a surface of a balloon. Each dilation element is connected to an outer surface of the balloon by a connector. The connector is sufficiently sized and designed to undergo stress-induced plastic deformation incurred during blow molding so that a significant portion of each of the dilation elements does not become absorbed into the wall of the final blow molded balloon, thereby maintaining the structural integrity of each of the dilation elements.

摘要： Described are devices useful for providing hemostasis at a vascular access site, and related methods. Such devices can include first and second implant members cooperable when forced together to expand the first implant member in a tissue tract at the site. Such devices can also include an anchor member and a tether attached thereto. The anchor member can be deployed distally to the first implant member, within a vessel, and the tether can be tensioned to apply counterforce to the first implant member as the second implant member is forced into cooperative contact to expand the first implant member.
