ABLATION DEVICE

摘要

An ablation device includes a waveguide that guides a pulse laser output from a laser output unit, a laser emitting unit that focuses the pulse laser guided by the waveguide using a lens, emits the pulse laser to a living body tissue, causes multiphoton absorption in a focal position of the pulse laser, and performs ablation on the living body tissue; and a balloon that sets a focus of the pulse laser as the laser emitting unit is positioned at a desired position inside a living body lumen.

主权项

1. An ablation medical device to ablate living body tissue or a living body comprising:
a catheter sized to be inserted into a living body lumen of the living body; a pulse laser output unit which outputs ultra-short pulse laser; a waveguide in the catheter, the waveguide being connectable to the pulse laser output unit to guide the ultra-short pulse laser output by the pulse laser output unit; and a focusing lens which focuses the ultra-short pulse laser guided along the waveguide on a focal position located on the living body tissue, and emits the pulse laser to ablate the living body tissue by causing multiphoton absorption at the focal position.
