COMBINED LASER ATHERECTOMY AND PRESSURE WAVE DEVICE

This abstract first appeared for US patent application 20250000581 titled 'COMBINED LASER ATHERECTOMY AND PRESSURE WAVE DEVICE

Original Abstract Submitted

an intraluminal device for delivering laser light and pressure waves includes a flexible elongate member positionable within a body lumen. the member includes an outer sheath; a laser catheter attached within the sheath; a sealed lens assembly located at the sheath's distal end; and a fluid chamber within the sheath, distal of the laser catheter and proximal of the lens assembly. the outer sheath includes a sealed acoustic window radially outward from the fluid chamber. when the chamber is filled with a fluid, a laser beam emitted by the laser catheter causes the photoreactive fluid to generate a pressure wave. when the chamber is filled with the fluid, a second laser beam emitted by the laser catheter exits via the transparent fluid and the sealed lens assembly. the sealed acoustic window and sealed lens assembly prevent the fluid from entering the body lumen.
