Tissue ablation with irreversible electroporation

Abstract: 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.

Irreversible electroporation to control bleeding

Abstract: A method of stopping or controlling bleeding by the placement of electrodes into or near the vicinity of vessels is disclosed. Then the application of electrical pulses causing irreversible electroporation of vessel and blood cells throughout the entire area of current flow the bleeding is stopped or controlled. 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. Through the use of irreversible electroporation bleeding can be stopped or controlled without inducing thermal damage.
