Floating Ball

This technology combines a conductive fluid with radiofrequency energy. The conductive fluid is infused at the point of tissue contact by means of a ball at the end of the handheld device, while the thermal energy seals the tissue. By shrinking the natural collagen in the tissue, blood flow is stopped, and the tissue is sealed. While at the point of contact the temperature reaches 350°C, the fluid delivered at the tip of the handheld device cools the tissue and avoids the formation of es char and tissue burning. The floating ball can coagulate vessels or ducts up to 10 mm in diameter. The major drawback in the use of this device in living donor hep-atectomies is the spreading of the heat around the ball, which may cause damage to the vascular and biliary structures that must be left intact for the subsequent implantation [28].
