摘要： An expandable venous valve having a support structure that is configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame sections or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure.

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： An expandable stent is provided. The stent has a ring architecture in which a plurality of connector segments join a plurality of ring structures to form the stent. The ring structures are an endless pattern of unit structures, each of which has two lateral arms and a central portion, and is inverted with respect to the immediately adjacent unit structures of the same ring structure. The connector segments have an undulating portion and can be axially displaced relative to other, circumferentially adjacent connector segments when the stent is in an unexpanded configuration. The stent can include axial portions in which connector segments are axially displaced from circumferentially adjacent connector segments, and can include other axial portions in which connector segments are axially aligned with circumferentially adjacent connector segments. A delivery system that includes a stent accordingly to the present invention is also provided.

摘要： A stent graft delivery system (50) has a stent graft (74) retained on it. The stent graft has an exposed proximally extending self expanding stent (76) which is retained in a distally opening capsule (78) at the distal end of a nose cone dilator (58) on the delivery system. A trigger wire (80) extends from a release mechanism (82) the distal end of the delivery system into a first aperture (84) in the capsule, around a proximal bend (86) of the exposed stent and out of the first aperture in the capsule and extending proximally into a second aperture (88). The trigger wire prevents premature release of the exposed stent.

摘要： An endoluminal vascular repair system includes an aorta stent graft having a fenestration with a first reinforcement around the fenestration. The fenestration aligns with a branch vessel when deployed. A branch vessel stent graft has a flaring portion at a proximal end of the branch vessel prosthesis that has a second reinforcement around its circumference to engage the reinforcement around the fenestration, and a tubular portion. When deployed, the flaring portion retains the proximal end within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel.
