    摘要: Methods and systems facilitate catheterization of a living subject by passing a fluid through an irrigation conduit. Heat energy is delivered to the conduit to create a heated pod of irrigation fluid that propagates downstream from the heat source. A departure time of the pod from a first location in the conduit is recorded, and an arrival time of the pod is detected at a second location that is downstream from the first location. A transit time of the pod from the first location to the second location is determined, and the flow of the fluid is adjusted responsively to the transit time.

    摘要: An irrigated medical device, including an inlet tube configured to receive an irrigation fluid from a pressurized fluid source, at least first and second outlet tubes configured to deliver the irrigation fluid to respective outlets of the device, a manifold containing a chamber coupled between the inlet tube and at least the first and second outlet tubes, and a ball including a magnetic material contained inside the chamber. The irrigated medical device also includes a magnetic field generator disposed outside the chamber and configured to generate a variable magnetic field within the chamber so as to move the ball between at least a first position in which the first outlet tube is blocked, a second position in which the second outlet tube is blocked, and a third position, in which neither of the outlet tubes is blocked.

    摘要: A method and apparatus for treating tissue are disclosed, including intra-operative mapping of a probe ablation zone. The method uses a system that maps the proximal and distal margins of the probe ablation zone using tools that access the ablation target. In some embodiments, the tools comprise a bone drill, and an introducer assembly, including a cannula and a stylet. The tools have features or markings that cooperate to indicate which probe to use to achieve the desired ablation. The method further facilitates planning probe placement for delivering energy to treat (ablate) a desired ablation volume of a target tissue by using a system that maps both the target tissue and possible probe ablation zones.

    摘要: A method of performing an ablation procedure includes the initial step of supplying a fluid to a cooling chamber defined within an antenna assembly. The method also includes the steps of decreasing the temperature of the fluid to form a solid material and inserting the antenna assembly into tissue. The method also includes the step of supplying energy to the antenna assembly to treat tissue. Residual heat from the antenna assembly transitions the solid material back to the fluid. The method also includes the step of circulating the fluid within the antenna assembly to dissipate heat emanating from the antenna assembly.
