Abstract
A device, system, and method provides for removing deleterious tissue from healthy body tissue at a site inside a patient. The device includes a steerable electrosurgery device having a electrode to cut a core through tissue, including tissue surrounding a perimeter of the deleterious tissue, and has a lumen for aspirating the cored tissue from the patient. The electrode may form a closed loop, and may be the active electrode of an electrosurgery system. Further, the electrode may have a narrow profile. In addition, the electrode may be arranged to coagulate the cut tissue. The system includes the device and a seal to limit air leaks and bleeding resulting from the removal of cored tissue.
Claims24
A device for removing deleterious tissue from healthy body tissue at a site inside a patient, comprising:
- a steerable electrosurgery device having an electrode to cut a core through tissue, including tissue surrounding a perimeter of the deleterious tissue, and having a lumen for aspirating the cored tissue from the patient.
A system for removing deleterious tissue from healthy body tissue at a site inside a patient and sealing the remaining tissue, comprising:
- a steerable electrosurgery device having a electrode to cut a core through tissue, including tissue surrounding a perimeter of the deleterious tissue, and having a lumen for aspirating the cored tissue from the patient;
- and
- a seal to limit air leaks and bleeding resulting from the removal of cored tissue.
A method for removing deleterious tissue from healthy body tissue at a site inside a patient, including the steps of:
- providing a steerable electrosurgery device having an electrode to cut a core through tissue, including tissue surrounding a perimeter of the deleterious tissue, and having a pathway for removing cored tissue from the patient;
- placing the electrode of steerable electrosurgery device inside the patient to a point where the electrode is in proximity with the deleterious tissue site;
- coring tissue with the steerable electrosurgery device from the point in proximity to the deleterious tissue site to and including the deleterious tissue;
- removing the cored tissue from the patient through the pathway;
- and
- sealing the core resulting from the removal of cored tissue from blood and air flow.
A device for removing deleterious tissue from health body tissue at a site inside a patient, comprising:
- steerable electrosurgery means for coring through tissue, including tissue surrounding a perimeter of the deleterious tissue;
- and
- aspiration means for removing cored tissue from the patient.
A device for biopsying deleterious tissue at a site inside a patient, comprising:
- a steerable electrosurgery device having a electrode to cut a core through tissue, including the deleterious tissue, and having a lumen for aspirating the cored tissue from the patient.
