Abstract

A medical prosthesis 3 comprising a tubular framework knitted from a single strand of shape memory metal. The wire may be warp knitted or weft knitted by means of a lock stitch or tuck stitch. The shape memory metal may be nitinol and exhibit thermal shape recovery properties at body temperature. The stent may be of uniform dimension along its length, or may be frusto conical or possess a sheath cover extending along its entire length. The prosthesis may be coated in bioactive substances <I>e.g</I> antibiotics, anti-thrombogenic agents, monoclonal antibodies, steroids. A method of emplacing the stent comprising loading it within a catheter, restricting flow through a blood vessel ahead of the stent by inflating a balloon, withdrawing the catheter allowing the stent to expand and removing the deflated balloon through the expanded stent.
