摘要： A two-stage method of compressing a stent entails providing an expandable stent (100,105) in a radially expanded state. An outward pressure is applied to an inner surface of the tubular framework to support the stent, and a diameter of the stent is reduced to a first compressed diameter (D1) while applying the outward pressure. The outward pressure is halted after reaching the first compressed diameter. According to an embodiment in which the stent is balloon-expandable, a delivery balloon catheter (130) comprising an uninflated balloon in a delivery configuration is inserted into the lumen after halting the outward pressure. The diameter of the stent is reduced to a second compressed diameter (D2) smaller than the first compressed diameter to crimp the stent onto the delivery balloon catheter.

摘要： A coated stent (20) for use in a medical procedure and methods of manufacturing the coated stent (20) are described. A stent component (30) has an expanded state in which an inner diameter (ds) of the stent (30) is less than or equal to an outer diameter (dc2) of a coating (40), thereby causing an inner surface (35) of the stent (30) to engage the outer surface (42) of the coating (40). In one exemplary method of manufacture, the stent (30) is disposed over the coating (40) when the coating (40) is provided with a first, smaller outer diameter (dc1). The coating (40) then is radially expanded to a second, larger outer diameter (dC2), which is greater than or equal to the inner diameter (ds) of the stent (30), to cause the outer surface (42) of the coating (40) to engage the inner surface (35) of the stent (30).

摘要： A stent tissue graft prosthesis (20) for repairing, excluding and/or reinforcing a vessel, duct and the like in a patient. The prosthesis includes an inner expandable stent (21) of which a tissue graft (24) and preferably a multilayered tissue construct (33) is disposed thereon for application to the host tissue of a vessel, duct and the like. The tissue construct includes an extracellular matrix material (36) such as small intestine submucosa (37) for remodeling the host tissue into the prosthesis. The prosthesis further includes an outer tubular member (25) such as an outer expandable stent (44) for retaining the tissue graft on the inner stent. The ends of the inner and outer stents are coincident with or extend beyond the ends of the tissue graft to prevent eversion or fold back of the tissue graft during withdrawal of a delivery catheter in a placement procedure.

摘要： Apparatus and methods are provided for improved deployment of self-expanding stents. One advantage of the improved delivery system is that energy storage within a portion of an outer sheath and/or an inner tube may be reduced during the deployment of the stent. In a first embodiment, the outer sheath and the inner tube may be coupled together using a plurality of engaging threaded members, such that circumferential rotation of the inner tube with respect to the outer sheath retracts the outer sheath to deploy the stent. In an alternative embodiment, a fluid reservoir may be provided between the inner tube and the outer sheath. A proximal sealing ring may be disposed annularly between the inner tube and the outer sheath, such that when the fluid reservoir is filled, the proximal sealing ring is urged proximally to engage and retract the outer sheath. Using these techniques, energy build-up in the outer sheath and/or inner tube may be substantially reduced and improved accuracy in deploying the stent may be achieved.
摘要翻译： 提供了用于改进自扩张支架部署的装置和方法。 改进的输送系统的一个优点是在支架的展开期间可以减少外护套和/或内管的一部分内的能量储存。 在第一实施例中，外护套和内管可以使用多个接合螺纹构件联接在一起，使得内管相对于外护套的周向旋转缩回外护套以展开支架。 在替代实施例中，可以在内管和外护套之间设置流体储存器。 近端密封环可以环形地设置在内管和外护套之间，使得当流体储存器被填充时，近端密封环被向近侧推动以接合和缩回外护套。 使用这些技术，可以显着地减少在外护套和/或内管中的能量积累，并且可以实现部署支架的提高的精度。

摘要： A percutaneous release mechanism (57) for use with an intravascular treatment device (11) in an intravascular treatment system (10). The release mechanism includes an inner member (17) having a connection mechanism (18) positioned about the distal end (14) thereof for interconnection with another connection mechanism (12) positioned on an intravascular treatment device. The release mechanism also includes an outer member tube (13) of which the inner member is positioned therein. The first and second connection mechanisms are interconnectable and positionable in the passage (16) of the tube for delivering the treatment device in a delivery state to the treatment site. The release mechanism also includes a handle (37) having parts (38, 39) connected to the inner member and outer tube, whereby movement of the proximal end of the inner member is translated to the distal end thereof for extending the interconnected connection mechanisms from the passage of the outer member tube and positioning the treatment device in a treatment state. The intravascular treatment system includes the percutaneous release mechanism along with the intravascular treatment device. The treatment device includes an occlusion coil (23) and a rigid tube (36) connected to the flexible outer member tube (35) for maintaining the delivery coil in a delivery state. In another example, the treatment device includes a blood clot filter (40) in which the percutaneous delivery mechanism is adapted for connection thereto.
