PLANAR-SHAPED THERMAL BALLOON FOR MESENTERIC FAT REDUCTION
PLANAR-SHAPED THERMAL BALLOON FOR MESENTERIC FAT REDUCTION
A surgical device for reducing visceral fat in the abdominal cavity comprises an elongate shaft and an inflatable member. The inflatable member comprises a small-profile deflated configuration for being advanced into the abdominal cavity and a large-profile inflated configuration comprising a planar distal treatment surface for treating the visceral fat. The thermal fluid, preferably a gas, is circulated through the inflatable member at a temperature range sufficient to cause cryolipolysis to the fat cells but not damage non-target tissues. The inflatable member can have several chambers, reinforcing members, and ports to provide controlled flow patterns that maintain the shape of the inflatable member when inflated.
