Abstract
An improved stent apparatus for intraluminal use in the body of an animal. The apparatus is of resilient material disposed in a tubular configuration about a central axis, which carries ratchet apparatus in the form of catch and latch apparatus having a selectively removable latch. The stent is expanded through the use of an angioplasty balloon to any selected one of a plurality of dilated positions. As the stent expands, the catches come into contact with the latch to prevent retraction of the stent apparatus. The latch communicates with a point external to the lumen, and is selectively removable from contact with the catches to enable the stent apparatus to return to its original diameter.
