Abstract
Abstract A process and apparatus for removing obstruction material from a stent which is located in a vessel in a body. The process generally involves threading a flexible casing into the material, and optionally, passing a tubular blade over the material to separate the material from the stent, and then withdrawing the flexible casing and the material out of the stent.
