ABSTRACT:
Apparatus and methods are provided for recanalizing stented regions within the vasculature which have become restenosed. A shearing body is displaced within the stented region in order to dislodge the stenotic material from an interface envelope defined by the inner surface of the stent. Usually, the shearing body will be compliant and sized slightly larger than the stent in order to remove stenotic material substantially uniformly around the entire interface envelope. The shearing body may be in the form of a brush, helical row, spaced-apart disks, solid compressible body, or a variety of other specific configurations.
