A medical construct particularly useful as a stent, comprising an axially compressible bellows of a material and dimensions sufficient to provide negligible resistance to flexure transverse to the axis and negligible recoil under compression or expansion along the axis, and apparatus and a method for deploying the same.

Bellows medical construct and apparatus and method for using same

There is described a process for deploying a medical construct in a body cavity, so as to function for example as a stent in a body lumen. The construct is used by forming a coil from a strand that has an interior and an exterior portion, and thereafter heating while expanding the coil so as to melt only the exterior portion. When that melted portion resolidifies with the coil in the expanded state, the coil's integrity and resistance against forces such as compression is maintained by the unmelted but stretched interior portion, and the expanded shape is maintained by the adhesiveness of the solidified exterior portion.
