First Claim
1. A device for cutting or ablating tissue in a human or veterinary patient, said device comprising:
- an elongate probe having a distal end;
a tissue cutting or ablating apparatus; and
a protector that extends from the probe, said protector having a first side and a second side, said protector being positionable such that tissue that is to be cut or ablated is adjacent to the first side of the protector and tissue that is to be protected is adjacent to the second side of the protector, said protector being at least partially formed of an insulating material;
the tissue cutting or ablating apparatus being useable to cut or ablate tissue that is located adjacent to the first side of the protector without causing substantial damage to tissue located adjacent to the second side of the protector.

Abstract
A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be advanceable into tissue or otherwise placed and positioned within the patient'"'"'s body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

35. A method for manufacturing a device useful for cutting or ablating tissue in a human or veterinary patient, the method comprising:
-
A) providing an outer tube and an inner tube;
B) positioning the inner tube within the outer tube such that a distal portion of the inner tube extends beyond a distal end of the outer tube;
C) forming a protector on the distal end of the outer tube by a. cutting at least one notch in the distal end of the inner tube to form at least one leg, and b. bending the first leg to form a protector having a first side and a second side, and D) positioning an electrosurgical cutting or ablating apparatus at the distal portion of the inner tube and spaced apart from an adjacent the first side of the protector. - View Dependent Claims (36, 37, 38, 39, 40)

41. A method for cutting or ablating a strip of tissue from a tissue mass, said method comprising the steps of:
-
A) providing a device which comprises;
i. an elongate probe having a distal end;
ii. a tissue cutting or ablating apparatus; and
iii. a protector that extends from the probe, said protector having a first side and a second side, said protector being positionable such that tissue that is to be cut or ablated is adjacent to the first side of the protector and tissue that is to be protected is adjacent to the second side of the protector, said protector being at least partially formed of an insulating material;
wherein the tissue cutting or ablating apparatus is useable to cut or ablate tissue located adjacent to the first side of the protector without causing substantial damage to tissue located adjacent to the second side of the protector B) positioning the device within or adjacent to the mass of tissue; and
C) advancing the device such that some of the in a first direction while using the tissue cutting or ablating apparatus to cut or ablate tissue that becomes positioned adjacent to the first side of the protector. - View Dependent Claims (42, 43, 48, 49, 50, 51)
