Abstract
An irreversible electroporation (IRE) includes setting an initial IRE protocol for applying IRE pulses by electrodes of a catheter placed in contact with tissue in an organ. A notification is issued to a user upon determining that the initial IRE protocol is expected to cause bubbles in blood. In response to the notification, user input is received from the user, that selects between the initial IRE protocol and an alternative protocol that is not expected to cause the bubbles. The IRE pulses are applied according to the initial IRE protocol or the alternative IRE protocol, depending on the user input.
Claims8
An irreversible electroporation (IRE) method, comprising:
- setting an initial IRE protocol for applying IRE pulses by electrodes of a catheter placed in contact with tissue in an organ;
- issuing a notification to a user upon determining that the initial IRE protocol is expected to cause bubbles in blood;
- receiving from the user, in response to the notification, user input that selects between the initial IRE protocol and an alternative protocol that is not expected to cause the bubbles;
- and
- applying the IRE pulses according to the initial IRE protocol or the alternative IRE protocol, depending on the user input.
An irreversible electroporation (IRE) system, comprising:
- a user interface configured for setting IRE protocols for applying IRE pulses by electrodes of a catheter placed in contact with tissue in an organ;
- and
- a processor, which is configured to:
- issue a notification to a user upon determining that an initial IRE protocol is expected to cause bubbles in blood;
- receive via the user interface, in response to the notification, user input that selects between the initial IRE protocol and an alternative protocol that is not expected to cause the bubbles;
- and
- apply the IRE pulses according to the initial IRE protocol or the alternative IRE protocol, depending on the user input.
