Appl. No.:

11/314332

Inventors:

Stanley Humphries - Albuquerque NM, US
Kyle R. Rick - Boulder CO, US
David A. Schechter - Longmont CO, US
Nahum Goldberg - Boston MA, US

Assignee:

Covidien AG - Neuhausen am Rheinfall

International Classification:

G06F 9/45

US Classification:

703 11, 606 39, 606 32, 606 34, 606 49, 600420, 600458, 600374

Abstract:

A system and method for performing a simulation of an electrosurgical procedure are disclosed. The method includes the steps of generating a three-dimensional medium, which includes one or more material regions representing a physical object. The method also includes the steps of dividing the medium into multiple hexahedron elements to generate a three-dimensional conformal mesh and assigning each element to the material region. The method further includes the steps of calculating an electrical energy solution and a thermal transport solution and generating graphical representations illustrating one or more aspects of the electrical energy and the thermal transport solutions.

US Classification:

703 11, 600416, 600420

Abstract:

A method for performing a simulation of an electrosurgical procedure is provided. The method includes the step of generating a three-dimensional model of a medium comprising one or more material regions representing a physical object or a region of the tissue. The method also includes the step of calculating one of an electrical energy solution and a thermal transport solution based on one of a mathematical model and finite element method. The method further includes the step of updating one or more property values of the material region in response to temperature changes based on an empirically derived value, wherein one of the electrical energy solution and the thermal transport solution is updated as a function of the updated property value.

US Classification:

606 41

Abstract:

A tissue ablation device is provided for use in soft tissue and/or in bone. It is configured to include an inner probe with a first electrode and a second electrode and an outer needle through which the inner probe extends. After the inner probe is directed therewithin to a target, the outer needle can be withdrawn to expose space between the first and second electrodes to form an RF or other energy field for tissue ablation therebetween upon actuation of an energy source. Such embodiments may include methods for tissue ablation and placement of stabilizing materials.
