Segmentarily expandable tubular endoluminal prosthesis

Abstract

Abstract The invention concerns a segmentarily expandable tubular endoluminal prosthesis (a stent) comprising a helically coiled, or otherwise as a tubular structure shaped, wire of Nickel-Titanium alloy with shape memory effect (SMA). In its primary shape the diameter of one or more segments of the stent is considerably greater than the rest of the diameter of the stent. In its secondary shape the segments and possibly the total stent diameter is reduced to an extent allowing insertion of the stent into a body cavity. Once in the desired position in the body cavity the stent can return to its primary shape by exposing the stent to heat.
