Abstract: An apparatus for cooling an ablation probe includes a cassette receptacle configured to accept a cassette including a supply tube for supplying a coolant to the ablation probe. The apparatus also includes a pump head movably positioned proximate the cassette receptacle. The pump head is configured to move between a loading position and an operating position. The pump head includes one or more rollers configured to engage the supply tube of the cassette when the pump head is in the operating position. The apparatus also includes an actuator coupled to the pump head. The actuator is configured to move the pump head between the loading position and the operating position.

Abstract: A fiber producing apparatus and method for producing fibers having at least two different dimensions or characteristics. The apparatus cuts fibers of varying length, thickness, and width by varying a cutting stroke length, using a cutting plate having different cutting blades, and applying varying pressure on a material during the cutting process. The fibers of the present invention are moldable and can be used as an implant having a structure that mimics native or natural bones. The ability to mimic natural bone improves cellular infiltration and bone growth.
