Abstract
A tissue treatment system configured to ablate a tissue, the system comprising: (a) a clamp assembly comprising a first jaw mechanism and a second jaw mechanism configured to receive and compress a tissue therebetween; (b) a first electrode disposed on the first jaw mechanism and configured to contact the tissue; and (c) a second electrode disposed on the second jaw mechanism and configured to contact the tissue, where the first electrode and the second electrode are configured so that at least one of an ablation energy output of the first electrode and an ablation energy output of the second electrode is automatically adjusted to accommodate variable tissue thicknesses between the first electrode and the second electrode.
Claims10
A method of ablating a tissue, the method comprising:
- compressing a target tissue including myocytes between a first jaw comprising a first electrode and a second jaw comprising a second electrode;
- non-thermally ablating the myocytes by delivering voltage pulses at or above 500 volts to the target tissue via at least one of the first electrode and the second electrode;
- wherein delivering voltage pulses to the target tissue via the at least one of the first electrode and the second electrode comprises delivering about 5-50 pulses at about 1500-3000 Volts with pulse durations of about 0.02-0.1 milliseconds over a time interval of about 1-60 seconds.
