Cavitation Medication Delivery System
First Claim
1. A method for delivering a substance to a target region in a vapor form, the method comprising:
- placing a fluid within an interaction zone;
positioning an electromagnetic radiation emitting fiber optic tip within the interaction zone, the fiber optic tip containing the substance that is transparent to a first wavelength of energy and that substantially absorbs a second wavelength of energy;
creating a vapor bubble within the interaction zone by exposing the fluid to electromagnetic radiation at the first wavelength, the electromagnetic radiation at the first wavelength being substantially absorbed by the fluid in the interaction zone;
releasing the substance in a vapor form into the vapor bubble by exposing the substance to electromagnetic radiation at the second wavelength, the electromagnetic radiation at the first and second wavelengths being emitted by the fiber optic tip; and
using the vapor bubble to deliver the substance to the target region in the vapor form.

Abstract
Systems and methods for delivering a substance to a target region in vapor form are provided. A fluid is placed within an interaction zone, where the interaction zone is a volume that extends into the target region or that is adjacent to the target region. A fiber optic tip is placed within the interaction zone. The fiber optic tip contains the substance that is transparent to a first wavelength of energy and that substantially absorbs a second wavelength of energy. A vapor bubble is created within the interaction zone by exposing the fluid to electromagnetic radiation at the first wavelength, where the radiation at the first wavelength is substantially absorbed by the fluid. The substance is released in vapor form into the vapor bubble by exposing the substance to electromagnetic radiation at the second wavelength. The fiber optic tip emits the radiation at the first and second wavelengths.

21. A method for delivering a substance to a target region, the method comprising:
-
placing a fluid within an interaction zone, the interaction zone being a volume that extends into the target region or that is adjacent to the target region; positioning an electromagnetic radiation emitting element within the interaction zone, the element containing the substance that is transparent to a particular wavelength of energy; creating a vapor bubble within the fluid by exposing the fluid to electromagnetic radiation at the particular wavelength, the electromagnetic radiation at the particular wavelength being emitted by the electromagnetic radiation emitting element and being substantially absorbed by the fluid in the interaction zone; and during the creation of the vapor bubble, releasing the substance into the vapor bubble.
