Patent ID: 7842029

Claim:
A method to treat a target, comprising: applying a device to a biological external tissue, the device having a peripheral border that includes an outer portion that is brought into contact with a first portion of the biological external tissue; applying a first negative pressure inside the outer portion of the device through a conduit coupled to the outer portion of the device, the device having an inner chamber which is surrounded, at the peripheral border, by the outer portion, and wherein the inner chamber occupies a space above a second portion of the biological external tissue and wherein the first portion of the biological external tissue surrounds the second portion of the biological external tissue; furnishing a liquid to the second portion of the biological external tissue inside the inner chamber of the device; applying a second negative pressure, through an opening in the inner chamber of the device, inside the inner chamber equal to or lower than a vapor pressure of the liquid while the biological external tissue is coated with the liquid; applying an energy to the second portion of the biological external tissue inside the inner chamber; and causing the liquid to evaporate at least in part via the second negative pressure.
