摘要： Various stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system (800) comprises proximal (802) and distal (822) components, each comprising a graft (805, 825) having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component comprises a proximal stent (804) having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices greater than the radius of H is curvature of at least one of the distal apices. The distal component comprises a proximal z- stent (830a) coupled to the graft (825), where the proximal end of the graft comprises at least a scallop (845) formed therein that generally follows the shape of the proximal z- stent. Further, the distal component may comprise at least one z- stent (834) coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.

摘要： An expandable stent (200) for use in a body vessel comprises a thin- walled tubular framework (205) including two or more circumferentially adjacent end members (210) extending in a longitudinal direction from an end of the framework. In a delivery configuration of the tubular framework, the end members have an interlocking configuration. Each end member has a first interlocking side (235) and a second interlocking side (240), where the first interlocking side has a circumf erentially directed protrusion (225) and the second interlocking side has a circumferentially directed recess (230). The protrusion of a first end member mates with the recess of a second end member. In an expanded configuration of the tubular framework, the end members are disengaged from the interlocking configuration. Each end member may be an eyelet (215) including an opening for a radiopaque rivet. A method of preparing the expandable stent for delivery into a body vessel is also described.

摘要： A barb for anchoring an implantable medical device to a body vessel comprises a thin-walled body portion for engagement with a structural element of an implantable medical device and a penetrating element extending from the body portion. The body portion has a longitudinal axis. The penetrating element includes a tip portion for anchoring into tissue and a base portion between the tip portion and the body portion. In a deployed configuration of the barb, the base portion curves away from the longitudinal axis at a first curvature and the tip portion curves toward the longitudinal axis at a second curvature which is opposite in sign from the first.

摘要： A stent graft delivery device (1) has an elongated extension piece (20) extending from its proximal end of the introducer portion (3). The elongate extension piece is selectively separable from the introducer portion. A plurality of auxiliary guide wires (50) extend from through the stent graft delivery device and through the elongate extension piece. The auxiliary guide wires can cross over at the proximal end of the extension piece and return. The stent graft delivery device can be introduced into a patient via a femoral artery and the elongated extension piece can extend out an artery of the thoracic arch whereby to extend the auxiliary guide wires out of such an artery to give through and through guide wires. Catheterization of pararenal arteries is then possible via a brachial route.

摘要： An implantable medical support frame (104) having a central longitudinally extending axis is expandable from a collapsed configuration having a first diameter to an expanded configuration having a second diameter. The frame also includes an anchoring mechanism with an elongate member (110). At least a portion of the elongate member is slidably disposed within a retaining structure when the frame is in the collapsed configuration. When the frame expands from the collapsed configuration to the expanded configuration, a portion of the elongate member is advanced out of the retaining structure such that the portion of the elongate member protrudes radially outward of the frame at an angle to the axis, thereby forming an anchor. A length of the protruding portion of the anchor increases as the frame expands from the collapsed configuration to the expanded configuration.
摘要翻译：具有中心纵向延伸轴线的可植入医疗支撑框架（104）从具有第一直径的收缩构造可扩展至具有第二直径的扩张构型。框架还包括具有细长构件（110）的锚固机构。当框架处于折叠构型时，细长构件的至少一部分可滑动地设置在保持结构内。当框架从折叠构型膨胀到扩展构型时，细长构件的一部分从保持结构中推出，使得细长构件的该部分以与轴线成一定角度的径向向外突出地突出，从而形成锚。锚的突出部分的长度随着框架从折叠构型扩展到扩展构型而增加。

摘要： A stent (20) for use in a medical procedure that comprises a series of proximal apices (22a, 22b) disposed at a proximal end (22) of the stent and a series of distal apices (62a, 62b) disposed at a distal end (24) of the stent. A trigger wire (84) is arranged to be coupled to at least one of the proximal apices (22a, 22b) to restrain the proximal end of the stent (22) during delivery. In a first embodiment, a first proximal apex comprises a bore (31) for receiving the trigger wire (84), and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb (42). The trigger wire (84) therefore is only coupled to selected ones of the proximal apices. In another embodiment, a first proximal apex comprises a first bore (31) and a second, adjacent proximal apex comprises a second bore (41 ), such that a single trigger wire (84) may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

摘要： Various stent structures are provided with improved axial and torsional flexibility. One type of stent structure includes multiple segmented stent structures connected to each other by biodegradable interconnectors. A delivery system adapted to delivery the multiple segmented stents is also described. Another type of stent structure includes biodegradable connectors that are incorporated into a framework of non-biodegradable interconnecting members that form the support structure of the stent. The biodegradable connectors in both stent structures degrade or are absorbed after the stent is deployed. Stabilizing elements may be provided to the stent structures to supplement the stiffness of the stent with stability during loading and deployment.
