Abstract
A catheter for scoring or slicing a lesion. The catheter has a first receiver at a distal end of an expandable portion of the catheter shaft. A first carrier at least partially within the first receiver is moveable axially along the catheter shaft to deploy a first cutter along the expandable portion for cutting or scoring the lesion. In an alternative embodiment, the first carrier may be a wire having a loop, and thus forming a first length including the first cutter and a second length including a second cutter. Actuation of the wire thus causes simultaneous, reciprocal movement of the first and second cutters. Related methods are also disclosed.
