Abstract
An energy delivery probe and method of using the energy delivery probe to treat a patient is provided herein. The energy delivery probe has at least one probe body having a longitudinal axis and at least a first trocar and a second trocar. At least a portion of each trocar is disposed with the at least one probe body. The distance between the first trocar and the second trocar is adjustable between a first position and a second position. Each of the deployed electrodes has an energy delivery surface of a sufficient size to create a volumetric ablation zone between the deployed electrodes. The energy delivery probe is connected to an energy source. At least one cable couples the energy delivery probe to the energy source.
Claims54
An energy delivery probe for treating a patient, comprising:
- at least one probe body having a longitudinal axis;
- at least a first trocar and a second trocar, wherein
- a portion of each trocar is disposed with the at least one probe body, and wherein the trocars each comprise
- a proximal portion and a distal portion, wherein the distal portion is capable of piercing tissue;
- and
- at least one hollow lumen extending along a longitudinal axis,
- wherein the distance between the first trocar and the second trocar is adjustable between a first position and a second position.
An energy delivery probe for treating a patient, comprising:
- at least one probe body having a longitudinal axis;
- at least a first trocar and a second trocar, wherein
- the first and second trocars are defined in a substantially parallel relationship relative to each other;
- a portion of each trocar is disposed with the probe body, and wherein the trocars each comprise
- a proximal portion and a distal portion, wherein the distal portion is capable of piercing tissue;
- a hollow lumen extending along the longitudinal axis a plurality of electrodes, each electrode having a proximal portion and a distal portion,
- wherein the plurality of electrodes are at least partially positioned within the trocars and adapted to be deployed radially away from the at least one probe body and into tissue of the patient, and wherein the plurality of electrodes are each adapted to receive electrical treatment energy from an energy source.
A spacer device for use with an energy delivery probe, wherein the spacer device comprises at least a first bore and a second bore, wherein each bore extends through the spacer device such that the bores are in communication with the exterior of the spacer device, wherein each bore has an inner surface, and wherein each bore is capable of receiving a portion of an outer surface of the first trocar and the second trocar to create an interference fit between the inner surface of the bores and the outer surfaces of the trocars.
A method of treating a patient, wherein the method comprises:
- identifying a target tissue;
- providing at least one energy delivery probe, wherein the probe comprises at least one probe body, at least a first trocar and a second trocar having a longitudinal axis, and a plurality of electrode arrays, wherein the trocars are substantially parallel in relation to each other, and wherein the electrode arrays are defined within a portion of the trocars;
- inserting the first trocar and the second trocar into the tissue such that the target tissue is substantially positioned between the first and second trocars;
- deploying the plurality of electrode arrays radially away from the longitudinal axis of the trocars into the tissue;
- and
- delivering energy to the target tissue to ablate the tissue, thereby
- forming a first ablation zone.
A method of treating a patient, wherein the method comprises:
- identifying a target tissue;
- providing at least one energy delivery probe, wherein the probe comprises at least one probe body, at least a first trocar and a second trocar having a longitudinal axis, wherein the trocars are substantially parallel in relation to each other;
- inserting the first trocar and the second trocar into the tissue such that the target tissue is substantially positioned between the first trocar and the second trocar;
- and
- delivering energy to the target tissue to ablate the tissue, thereby
- forming a first ablation zone.
