Patent number: 6346104Abstract: A system (2,4), method and splitter (6) for ablating tissue (15) using radiofrequency (RF) energy is disclosed. The system (2,4) ablates tissue (15) using unipolar RF energy simultaneously delivered to multiple electrodes (22A-22D) in one or more probes (20). This is carried out by the multiple channel RF splitter (6) that can independently control the RP energy delivered through each channel (18) to a respective electrode (22A-22D) in a continuous manner. Each electrode (22A-22D) has a corresponding temperature sensor or transducer (36A-36D) that is processed independently so that the amount of RF energy delivered to each electrode (22A-22D) can be varied dependent on the temperature of the electrode (22A-22D) so that the lesion size produced by each electrode (22A-22D) can be accurately controlled. Preferably, each probe (20) has a needle-like structure with a number of electrodes (22A-22D) separated by insulative material and is adapted to puncture tissue.Type: GrantFiled: January 22, 1998Date of Patent: February 12, 2002Assignee: Western Sydney Area Health ServiceInventors: Michael Daly, Pramesh Kovoor, Konstadinos Hatzianestis, David Ross
