摘要： 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.
