Document Type and Number:
Japanese Patent JPH11512013
Kind Code:
A
Abstract:
A tubular graft/stent includes a tubular sheath ( 10 ) having at intervals along its length a plurality of ring-like rigid members ( 11 ), which are attached to the sheath around their respective circumferences and are made of a shape memory material, so that when the members ( 11 ) change shape the sheath ( 10 ) adopts a new cross section in conformity with them along its whole length. The members may be discontinuous to allow the adoption of a contracted shape in the martensitic phase and an expanded shape in the austenitic phase. A graft may also have a side tube ( 14 ) which can be inverted so as to be housed within the sheath.
