Abstract

A device for shaping tissue includes a tip with an internal close-looped circulation system. The tip is configured to connect to tubes. One tube is configured to connect to a submersible cold-water pump. Another tube is an outlet. The tip has a sapphire window on one face and, on opposite face, a shaft with a laser fiber therein, and an opening for laser beam to shine through.

First claim

We claim:

1. A device for shaping tissue, comprising:
a tip configured to connect to tubes;
wherein one tube is configured to receive a cooling fluid from a cold source;
wherein another tube is configured as an outlet for the cooling fluid;
wherein the tip has a window in one exterior planar face thereof and, on opposite exterior planar face thereof, a shaft with a laser fiber therein, and an opening in the opposite exterior planar face for a laser beam from the laser fiber to shine through;
wherein the tip is made of a laser non-transmissive material;
wherein the window is made of a laser transmissive material.

2. The device of claim 1 , wherein the tip is made of metal.

3. The device of claim 1 , wherein the tip is configured with an internal close-looped circulation system.

4. The device of claim 1 , wherein the cold source includes a cold-water pump.

5. The device of claim 1 , wherein the cold source includes an iced saline solution.

6. The device of claim 1 , wherein the window is a sapphire window.

7. The device of claim 1 , wherein the tip is configured to cool to 0° C.

8. A system for shaping tissue, comprising:
a computer;
a laser source, in communication with the computer, and configured to generate a laser beam;
a temperature sensor in communication with the computer;
a tip in communication with the temperature sensor and configured to:
receive and transmit the laser beam to the tissue; and
transfer heat from the tip to a cooling fluid inside the tip;

wherein the tip has a window in one exterior planar face thereof and, on opposite exterior planar face thereof, a shaft with a laser fiber therein, and an opening in the opposite exterior planar face for a laser beam from the laser fiber to shine through;
wherein the tip is made of a laser non-transmissive material;
wherein the window is made of a laser transmissive material.

9. The system of claim 8 , wherein the computer is configured to modulate the laser beam.

10. The system of claim 9 , wherein the computer modulates the laser beam in response to temperature signals from the temperature sensor.

11. The system of claim 8 , wherein the window is made of sapphire.

12. The system of claim 8 , wherein the tip includes a closed-loop circulation system that hold the cooling fluid.

13. The system of claim 8 , further comprising a cold source in communication with the tip.

14. The system of claim 8 , further comprising a discharge container in communication with the tip.
