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.
Claims20
A catheter for scoring or slicing a lesion in a vessel, comprising:
- a catheter shaft including a first receiver adjacent a distal end of an expandable portion of the catheter shaft;
- a first blade;
- and
- a carrier attached to the first blade, the carrier having a portion distal of the first blade positioned at least partially within the first receiver and moveable axially to deploy the first blade along the expandable portion in an expanded condition for scoring or slicing the lesion.
A catheter comprising:
- a catheter shaft having an expandable portion;
- and
- a first wire extending along the expandable portion, the first wire including a first blade adjacent a proximal end of the expandable portion and a second blade adjacent to a distal end of the expandable portion, the first wire adapted for moving the first blade along the expandable portion toward the distal end while moving the second blade along the expandable portion toward the proximal end.
A catheter for scoring or slicing a lesion in a vessel, comprising:
- a catheter shaft including a first receiver at a distal end of an expandable portion of the catheter shaft;
- and
- a first blade at least partially within the first receiver in a non-deployed position and moveable axially along the expandable portion of the catheter shaft to a deployed position for scoring or slicing the lesion.
