Abstract

See full text

Disclosed are a tool and a method for removing tissue inside a body vessel. A first helical coil has a first pitch and a first lumen. The first coil is threaded into a tubular hollow body that is lined with a spiral thread with a second pitch that is substantially the same as the first pitch. The hollow body may be a second coil. A first set of cutting elements extends from the first coil into the first lumen. A second set of cutting elements extends from the hollow body into the first lumen. The first and second sets of cutting elements are arranged with respect to each other such that a screw-like movement of the first helical coil relative to the hollow body causes a cutting element of the first set and a cutting element of the second set to pass each other closely enough to cut tissue.
