Abstract: A generally tubular stent-graft (24) has distal and proximal stent-graft ends (36, 38) and includes a generally tubular support element (30) and a covering element (32).

Abstract: A deployment system (10, 410) includes an inner shaft (36, 436), removably disposed in a self-expanding stent-graft (40), and shaped so as to define (a) at least one conduit therealong (50, 450), which is (i) not coaxial with the inner shaft (36, 436), and (ii) shaped so as to define at least first (52, 452) and second enclosed longitudinal segments (54, 454), and (b) a restraining longitudinal portion (56, 456) that is longitudinally disposed between the first (52, 452) and second enclosed longitudinal segments (54, 454).

Abstract: An endovascular system (10) includes an endovascular implant (20) and a delivery tool (30). The implant (20) is configured to assume a radially-compressed delivery state, and a radially-expanded deployment state. The delivery tool (30) includes a proximal main delivery catheter (36), having a distal portion (46) in which the implant (20) is disposed while in the radially-compressed delivery state; and a distal restraining assembly (50), which includes a restraining-assembly tubular shaft (52) disposed distal to the proximal main delivery catheter (36). The distal restraining assembly (50) is configured to assume an engaged state, in which the distal restraining assembly (50) prevents proximal displacement of the implant (20) relative to the distal restraining assembly (50), and a disengaged state, in which the distal restraining assembly (50) allows proximal displacement of the implant (20) relative to the distal restraining assembly (50). Other embodiments are also described.

Abstract: A closure includes a panel closing against a frame. A set of abutment surfaces for supporting the panel against applied forces is completed by a displaceable abutment block which selectively assumes an engaged state disposed between an abutment surface of the panel and an abutment surface of a strike jamb. The geometry of engagement is such that forces acting on the abutment block opposing opening of the panel are primarily compressive forces. Certain implementations additionally, or alternatively, employ abutment blocks for locking along the lintel or the threshold of the opening.
