Abstract
Official abstract text for this publication.
A stent-graft including a helically-wound stent component provided with a covering of graft material. It is removable from the site of implantation by gripping an end of the helically-wound stent component with a retrieval device and applying tension to the stent component. The use of such a retrieval device allows the stent-graft to be removed remotely, such as via a catheter inserted into the body at a different location from the implantation site. The design of the stent-graft is such that the stent component is extended axially while the adjacent portion of the graft separates between windings of the stent component. The axial extension of the stent component, with portions of the graft still joined to the stent component, allows the device to be unravelled and removed through a catheter of diameter adequately small to be inserted into the body cavity that contained the stent-graft.
First claim
Opening claim text (preview).
We claim: 1. A stent graft having a longitudinal direction and a circumferential direction, said stent graft comprising: a helically wound stent comprising longitudinally spaced elements, with helically wrapped expanded polytetrafluoroethylene (ePTFE) tape having weaker anisotropic strength properties due to uniaxially aligned fibrils along the length of the ePTFE tape, and the pitch angles of the helical stent windings and ePTFE tape windings are equal and parallel in order to al…
