Articulation device for selective organ cooling apparatus

摘要

A selective organ heat transfer device with deep irregularities in a turbulence-inducing exterior surface. The device can have a plurality of elongated, articulated segments, each having a turbulence-inducing exterior surface. A flexible joint connects adjacent elongated, articulated segments. The flexible joint may be a rubber tube or a metal tube of a predetermined thickness. An inner lumen is disposed within the heat transfer segments. The inner lumen is capable of transporting a pressurized working fluid to a distal end of the heat transfer element.
