A new method for the ablation of undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of the undesirable tissue through the application of electrical pulses causing irreversible electroporation of the cells throughout the entire area of the undesirable tissue. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The amount of tissue ablation achievable through the use of irreversible electroporation without inducing thermal damage is considerable.

Tissue ablation using pulse modulated radio frequency energy

Номер: US20120179154A1
Автор: Kimbolt Young, S. Nahum Goldberg
Принадлежит: Boston Scientific Scimed Inc

Tissue ablation systems and methods are provided. Ablation energy (e.g., radio frequency energy) is delivered to the tissue and a physiological parameter (e.g., impedance and/or temperature) indicative of a change in moisture concentration of the tissue is sensed. The ablation energy is alternately pulsed on and off to generate an energy pulse train, with the ablation energy being pulsed on if the sensed physiological parameter crosses a threshold value indicative of an increase in the moisture concentration, and being pulsed off if the sensed physiological parameter crosses a threshold value indicative of a decrease in the moisture concentration.
