International Classification:

A61F 7/12

US Classification:

607105

Abstract:

A surgical device controls the temperature of an organ such as a kidney during minimally invasive surgery. The device includes a number of chambers fed by a fluid port. At least one of the chambers includes one or more baffles so that a cooling fluid entering through the fluid port is selectively distributed in a desired manner about an enclosed organ. The device may be fabricated of materials that can be rolled, folded, or otherwise compressed into a form suitable for delivery to a minimally-invasive surgical site.

Abstract:

Portions of a feed liquid are passed through respective condensers and liquid-liquid heat exchangers. The feed liquid is then heated and injected into a first feed-liquid containment chamber, where vapor from the feed is passed through a first gas-permeable membrane and directed into a first condenser, where the vapor is cooled by the feed liquid passing through the first condenser and condenses as it cools to produce a first liquid permeate. The first liquid permeate is passed through the first liquid-liquid heat exchanger where the first liquid permeate is cooled by the feed liquid passing therethrough. After the vapor is removed from the feed liquid in the first feed-liquid containment chamber, the remaining feed liquid from the first feed-liquid containment chamber is injected into a second feed-liquid containment chamber, where the process is repeated. The first liquid permeate from the first liquid liquid-liquid heat exchanger is combined with the second liquid permeate from the second condenser to form a combined liquid permeate; and the combined liquid permeate is passed through the second liquid-liquid heat exchanger where the combined liquid permeate is cooled by the feed liquid passing therethrough.
