  • Patent number: 10582960
    Abstract: In one aspect, the present invention provides a method of cooling to produce selective disruption of visceral fat tissue in a non-infant human subject comprising infusing a cooled fluid into the abdominal or peritoneal cavity, or into other parts of the body containing visceral fat, to cool the proximal tissue sufficiently to selectively disrupt lipid-rich cells therein, for example, to promote subsequent damage and absorption of lipid-rich cells by the body without producing unwanted effects in non-lipid-rich cells; e.g., without injury to internal organ tissues that could otherwise produce life-threating risks. The cooled fluid can be infused using a catheter arrangement. The cooled fluid can be retained within the abdominal category for a particular duration, and then drained using the catheter arrangement.
