Definitions
- the graft is manoeuvred using a balloon catheter to the desired position in the vessel, where the ste is expanded outwardly by
- the invention provides an expandable stent for a tubular (eg. vascular) graft or prosthesis or for expanding or supporting a body passageway, said stent comprising a thin walled tubular member having therein a plurality of slots distributed circumferentially and longitudinally of said tube, characterised in that at least some of the slots have at least one locally-enlarged region, said regions defining an array of relatively weak portions in said tubular member whereby, on expanding said stent. said portions act as plastic hinges.
- a tubular eg. vascular
- prosthesis for expanding or supporting a body passageway
- said stent comprising a thin walled tubular member having therein a plurality of slots distributed circumferentially and longitudinally of said tube, characterised in that at least some of the slots have at least one locally-enlarged region, said regions defining an array of relatively weak portions in said tubular member whereby, on expanding said stent. said portions act as plastic hinges.
- the member is preferably of uniform thickness, for example 250 ⁇ m thick, and may be formed from medical grade stainless steel, for example 316L.
- the stent When for use in repair of an aortic aneurysm the stent has a length of typically 40 to 50mm, and a diameter of 5mm.
- First 106 and second 107 pairs of locally-enlarged regions are formed in each of the slots 104, thereby forming portions of locally reduced cross-section 118 in the elongate members 108.
- This is the preferred arrangement, but the invention is not limited to this particular number of locally-enlarged regions 106, 107.
- the locally-enlarged regions 106, 107 preferably take the form of round holes of diameter greater than the width of the slot and preferably at least twice as wide. For example, for a slot width of 200 ⁇ m or less, the
- each slot 104 contains two pairs of holes 106 and 107.
- the holes of each pair are situated equidistant from centre 1 16 of the slot.
- One pair, 107. is situated at the ends of the slots, whereas each of the other pair 106 is situated so as to be aligned axially of the stent with one of the pair of holes 107 in the circumferentially adjacent slot.
- the cross-section of the portions 118 are substantially reduced in comparison with the cross- section of material between unenlarged regions of the slots 104 of the stent.
