Embodiment approach

[0044] The surface dermal region 180 may also be pre-cooled prior to insertion of the needle 120, eg, using any of a variety of conventional cooling techniques. For example, convective or conductive techniques such as applying a cryogenic spray or contacting the tissue surface with a cooled object (eg, a cold piece of metal, a piece of ice, etc.) can be used. This surface cooling may help reduce and / or eliminate the perception of pain when needle 120 is inserted. Pre-cooling of the dermal layer 180 and / or adipose tissue 185 to be treated may also increase the efficacy of the exemplary cooling device 100 described herein. For example, using the exemplary embodiments of the invention described herein, pre-cooling of target tissue may require less heat to be removed to achieve a particular level of cooling. Pre-cooling of tissue adjacent to the target tissue can also reduce the flow of blood to the target area, which can reduce the rate at which the blood heats the area. Theref...

Abstract

Exemplary embodiments of apparatus and method for tissue cooling using a plurality of hollow needles to deliver a cooled fluid into the tissue can be provided. For example, a volume and / or temperature of the fluid can be controlled to cool the tissue to a particular temperature or to within a predetermined temperature range. A tissue surface overlying the tissue to be cooled can be pre-cooled using conventional cooling techniques to increase the efficacy of the exemplary procedure. The exemplary method and apparatus can be used, e.g., to disrupt or damage fatty tissue that may then be reabsorbed by the body.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 041,593, filed April 1, 2008, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a method and a device for cooling tissue, in particular for targeted cooling of subcutaneous tissue by directing a cooling fluid into the tissue with an array of hollow needles. Background technique [0004] Cooling biological tissue can be used for various purposes. For example, cooling fatty tissue can destroy the tissue and can lead to a decrease in the amount of fatty tissue. Fat or adipose tissue, including lipid-rich cells, can be selectively disrupted by cooling the tissue to a certain degree below normal body temperature. Shredded fat tissue can be reabsorbed by the body to a certain extent. [0005] Excess fat tissue can lead to various health problems such as high blood...
