Abstract
An intravascular lithotripsy apparatus is disclosed. The apparatus may include a balloon assembly that expands and provides shockwaves for any feasible lumen. The balloon assembly may be shielded by an outer catheter providing a smooth surface to ease advancement through the lumen. Also described herein are locking mechanism for securing dual catheters that may be incorporated with any of the apparatuses described.
Claims17
An intravascular lithotripsy apparatus comprising:
- an inner catheter comprising;
- a tapered element coupled to a distal end of the inner catheter;
- and
- a balloon assembly coupled to the inner catheter disposed proximal to the tapered element, wherein the balloon assembly includes one or more electrode pairs configured to emit an electric arc;
- and
- an outer catheter comprising:
- a lumen configured to concentrically surround and slidably couple to the inner catheter;
- and
- a tip disposed on a distal end of the lumen and configured to slidably engage with a landing zone of the tapered element.
