摘要：An improved stent apparatus for intraluminal use in the body of an animal. Theapparatus 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 aselectively removable latch. The stent is expanded through the use of an angioplastyballoon to any selected one of a plurality of dilated positions. As the stent expands, thecatches 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 removablefrom contact with the catches to enable the stent apparatus to return to its originaldiameter.
