Abstract
Embodiments disclosed herein are directed to devices, methods, and systems for the treatment of tissue using energy delivery. Specifically, certain embodiments may be used for the treatment of lung tissue, such as lung nodules, using RF ablation, via a catheter provided with a first electrode attached to a distal end of the catheter, wherein the first electrode is hollow, wherein the first electrode comprises a piercing tip configured to pierce through an airway all and a second electrode received in a movable manner within the first electrode, wherein the second electrode is extendable from the first electrode to form a first extended configuration.
Claims14
A device for the delivery of energy to a region of lung tissue, the device comprising:
- a catheter configured to be inserted into an airway;
- a first flexible electrode attached to the distal end of the catheter, wherein the first electrode is hollow, wherein the first electrode comprises a piercing tip configured to pierce through an airway wall;
- a second electrode received in a movable manner within the first electrode, wherein the second electrode is extendable from the first electrode to form a first extended configuration;
- and
- a first electrical lead in electric communication with the first electrode, and a second electrical lead in electric communication with the second electrode, wherein the first and second electrical leads are connectable to a source of electric power,
- wherein the second electrode extends proximally from the distal tip and
- surrounds the longitudinal axis of the first electrode.
A method of delivering energy to a region of lung tissue to be treated, the method comprising:
- inserting a catheter into a patient's airway, wherein a distal end of the catheter comprises a first electrode and a second electrode received in a sliding manner within the first electrode and configured to be extendable therefrom;
- navigating the catheter to an airway proximate the region of lung tissue to be Treated;
- piercing the airway with the first electrode so as to position the first electrode into or near the region of lung tissue to be treated;
- extending the second electrode into the region of lung tissue to be treated;
- activating a power source configured to deliver a therapeutic amount of energy to the region of lung tissue to be treated, wherein the power source is connected via a first electrical lead connected to the first electrode and a second electrical lead connected to the second electrode;
- and
- delivering energy to the region of lung tissue to be treated.
A system for the delivery of energy to a region of lung tissue, the system comprising:
- an energy delivery device comprising:
- a catheter configured to be inserted into an airway, the catheter comprising a first electrode and a second electrode;
- a handle attached at a proximal end of the catheter, the handle comprising a second activation toggle configured to extend the second electrode from the first electrode;
- wherein the second electrode is received in a movable manner within the first electrode, and wherein the second electrode is extendable from a distal end of the first electrode to form a first extended configuration;
- a power source connected to the first electrode and second electrode via first and second electrical leads, the power source configured to deliver RF energy;
- and
- a conduit insertable into an airway and selected from the group consisting of a bronchoscope and a guide sheath, the catheter being insertable and movable therein.
