    摘要: A fenestration (32) for a stent graft (30). The fenestration is an aperture in the biocompatible graft material and has at least one flap (38, 40) of a biocompatible graft material covering the aperture on the inside whereby the flap closes off the aperture but can be displaced to allow access through the fenestration. An array of such fenestrations may be placed on a stent graft to facilitate alignment of a branch vessel with a fenestration. A slip knot (46, 46) which can be released by forcing a dilator between the flaps can be used to hold the flaps together.

    摘要: A stent arrangement (12) and a stent graft (2) for curved lumens of the body. The stent graft has a tubular body (4) of a graft material, at least a portion of which may be arcuate to define an inner curved side (4b) and an outer curved side (4a) at least when deployed into the curved vessel. The stent graft has a plurality of self expanding stents (10, 12, 13) affixed thereto with a greater distance (11a) between the stents on the outer curved side than on the inner curved side. The stents can be normal, tapered on one or both ends or skewed. When mounted onto a deployment device a twist (152, 154) may be provided in the graft material between adjacent stents to nest the stents.

    摘要: A stent graft (10) has a tubular body (12) of a biocompatible material and at least one fenestration (18, 20). The or each fenestration has a tubular side branch stitched into it with a portion of the tubular side branch extending within the tubular body and a portion of the tubular side branch extending exteriorly of the tubular body. The stitching by which the tubular side branch is mounted into the fenestration extends circumferentially and diagonally from one end of the tubular side branch to the other such that the tubular side branch extends from the tubular body at an angle thereto. The tubular side branch has a resilient ring around at least one and preferably both ends thereof and a self expanding stent in between them. The tubular side branch can have a circumferential linear portion (46) at an inner end to engage against the inner wall (58) of the tubular body. The tubular side branch can have a stent made from a single wire forming a first ring (45), a second ring (47), the second ring defining a plane which is substantially parallel to and spaced axially apart from the plane of the first ring and a number of helical wire portions (49) extending between the first and second ring. Preferably the wire is a shape memory wire such as Nitinol™wire.

    摘要: A self expanding stent (10) formed from a resilient wire. The resilient wire comprises a zig zag form including an odd number of struts (12) such as seven struts and a bend (14) between each strut. There is first loop (18) of the resilient wire at the terminal end of a first strut and a second loop (18) of the resilient wire at the terminal end of a last strut. The stent as formed is substantially planar but in use is formed into a substantially cylindrical form (20) by being stitched onto a tubular body of a biocompatible graft material with at least the first strut and the last strut overlapping.

    摘要: A stent graft (20) has a tubular body of graft material (21), a number of self expanding stents (67) associated with the tubular body to define a fluid flow path through the stent graft when the self expanding stents are in their expanded configurations. At least one fenestration (22) in the tubular body is adapted to receive a side arm stent graft (71) to provide a fluid flow path from the tubular body and through the side arm stent graft. The or each fenestration has at least an inner ring (26) and an outer ring (24) and graft material (28) extending from the inner ring to the outer ring and the outer ring being in the tubular body of graft material. The inner ring can be hinged (31) to the outer ring or concentric within the outer ring. An intermediate ring (86) may also be used between the inner and outer rings.

    摘要: An endoluminal stent graft deployment system incorporating an anchor wire system for temporary anchoring of a stent graft on a delivery device. The anchor wire system has an anchor wire extending from the distal end of the device and releasably retained to the portion of the stent graft by a releasable retention system. The releasable retention system includes a bead on the proximal end of the anchor wire and an anchor release wire which has fastening arrangement to retain the release wire distally of the bead. The anchor release wire extends to a distal end of the deployment system so that the anchor wire release wire can be withdrawn thereby releasing the anchor wire.

    摘要: A stent graft introducer (1) which includes a handle arrangement which by telescopic movement of a slide or slide portions (104, 106) into a handle portion (100) causes controlled sequential deployment of a stent graft (14). Stops (218, 217, 218, 219) ensure actions are carried out in a selected order. A sheath (116) of the introducer is fixed to a slide portion such that with retraction of the slide portion the sheath is withdrawn from a stent graft retained on the introducer and at a selected position trigger wires retaining the stent graft onto the introducer are also released. Interconnections between the slides and the handle are provided to prevent relative rotation and re-extension after full retraction.
