Abstract
Methods and devices of treating an area of tissue of a patient are provided wherein the area of tissue includes a first tissue layer and a second tissue layer. The methods comprise the step of providing a liquid distribution source including a quantity of liquid and a nozzle in liquid communication with the liquid distribution source. The method further comprises the step of positioning the nozzle with respect to the area of tissue and disbursing the quantity of liquid through the nozzle with a velocity sufficient to substantially remove the first tissue layer without significant injury to the second tissue layer.

A method of treating an area of tissue of a patient with the area of tissue having a first tissue layer and a second tissue layer, comprising the steps of:
- providing a liquid distribution source including a quantity of liquid;
- providing a nozzle in liquid communication with the liquid distribution source;
- positioning the nozzle with respect to the area of tissue;
- and
- disbursing the quantity of liquid through the nozzle with a velocity sufficient to substantially remove the first tissue layer without significant injury to the second tissue layer.
A method of treating an esophagus of a patient comprising the steps of:
- providing a liquid distribution source including a quantity of liquid;
- providing a high-pressure source configured to apply pressure to the quantity of liquid;
- providing a nozzle in liquid communication with the liquid distribution source;
- positioning the nozzle with respect to the area of the esophagus;
- and
- disbursing the quantity of liquid through the nozzle with a velocity sufficient to substantially remove a mucosa layer of the esophagus without significant injury to the submucosal layer of the esophagus.
A device for treating an area of tissue of a patient, comprising:
- a liquid distribution source including a quantity of liquid;
- a high-pressure source configured to apply pressure to the quantity of liquid;
- and
- a nozzle in liquid communication with the quantity of liquid, wherein the device is configured to disburse the quantity of liquid through the nozzle with a velocity sufficient to substantially remove tissue from a patient.
