Abstract
A resurfacing device for removing a thin layer of diseased tissue while minimizing damage to the underlying tissue layers may include an expandable scaffold attached to a catheter shaft, at least one electrode disposed on the expandable scaffold, and a plurality of debridement elements disposed on an outer surface of the expandable scaffold. The expandable scaffold is positioned in apposition to the target tissue, the scaffold is expanded and the electrodes are activated to ablate diseased tissue. The scaffold is rotated to remove the ablated tissue.
Claims18
A resurfacing device comprising:
- a catheter shaft;
- an expandable scaffold attached to the catheter shaft;
- at least one electrode disposed on the expandable scaffold;
- and
- a plurality of debridement elements disposed on an outer surface of the expandable scaffold;
- wherein the debridement elements are elongate members each having a first end attached to the scaffold, and a second, free end extending radially away from the scaffold and extending towards a distal end of the scaffold from the first end.
A resurfacing device comprising:
- a catheter shaft;
- a self-expandable shape memory scaffold attached to the catheter shaft;
- at least one radiofrequency electrode disposed on the scaffold;
- and
- a plurality of debridement elements disposed on an outer surface of the scaffold;
- wherein the debridement elements are elongate members each having a first end attached to the scaffold, and a second, free end extending radially away from the scaffold and extending towards a distal end of the scaffold from the first end.
