    摘要: A portion of a covered stent is encapsulated with ePTFE, so that the unencapsulated portion, which is covered by a single ePTFE covering, imparts an unimpaired flexibility to the stent. One surface of the stent, either the luminal or abluminal surface, is covered by a single continuous layer of ePTFE, while limited regions, preferably near the ends of the stent, of the other surface are also covered by ePTFE. The regions covered by ePTFE on both surfaces become encapsulated when the ePTFE of one layer becomes bonded to second layer. By leaving a middle region of the stent unencapsulated, the stent retains flexibility similar to a bare stent, thereby reducing the loading and deployment forces.

    摘要: A tubular implant having an axial end to which is attached a ring of spoons of a material different from that of the implant. In another aspect, the invention provides a method of attaching elements to an axial end of a tubular implant comprising the steps of providing said elements on one end of a support tube having a radius substantially that of the implant in its unexpanded configuration, abutting the implant and elements end-to-end, fixing the elements to the implant, and parting the elements from the support tube. In a third aspect, the invention provides an implant carrying an element of another material, the element and implant having complementary tapered mating surfaces for achieving a taper form-fit of the element onto the implant.

    摘要: To improve radiopacity in a stent, and to reduce trauma while improving stent anchoring, imported beads are mounted To stent precursor matrices. Specially attractive is to provide a ring of such beads on the end rings of stent structures featuring a cylindrical mid length section flanked by outwardly flared ends. The beads can be of the same or different material from that of the stent matrix. The beads can assist in drawing the stent into a sleeve of a delivery system. Beads can be used to reveal features of the stent away from an end ring, such as a fenestration in the cylinder. Beads can be fixed in a position mechanically or by welding.

    摘要: The present invention provides an endoluminal prosthesis for deployment in a body lumen of a patient body, the prosthesis comprising a tubular fabric liner and a radially expandable frame supporting the liner. A plurality of imagable bodies are attached to the liner, the imagable bodies providing a sharp contrast so as to define a pattern which indicates the prosthesis position when the prosthesis is imaged within the patient body. Preferably, each imagable body comprises a plate having first and second opposed major surfaces and a passage therebetween to facilitate stitching the imagable body to the liner. Advantageously, the imagable bodies can be aligned with the openings of a perforate frame structure so that at least some of the imagable bodies are visible through associated openings, but need not actually be attached to the frame directly. Such imagable bodies are clearly visible when the prosthesis is deployed, and can also be sized to produce distinct images even when the frame is compressed within a delivery catheter, but will not interfere with the radial expansion of the frame during deployment.

    摘要翻译: 本发明提供一种用于展开在患者身体的体腔中的腔内假体,所述假体包括管状织物衬里和支撑衬垫的可径向扩张的框架。 多个可成像的主体附接到衬垫上,可成像体提供尖锐的对比度,以便当假体在患者体内成像时,形成指示假体位置的图案。 优选地,每个可成像体包括具有第一和第二相对主表面的板,以及其间的通道,以便于将可成像体缝合到衬垫上。 有利地,可成像体可以与穿孔框架结构的开口对齐,使得至少一些可成像体通过相关联的开口可见,但不需要实际上直接附接到框架上。 当假体被展开时,这样的可成像的身体是清晰可见的,并且即使当框架在输送导管内压缩时也可以确定尺寸以产生不同的图像,但是在展开期间不会干扰框架的径向扩张。
