Benefits of technology

[0015] The present invention provides a device for cutting or ablating tissue in a human or veterinary patient. This device generally comprises, consists essentially of, or consists of: a) an elongate probe having a distal end, b) a tissue cutting or ablating apparatus and c) a protector that extends from the probe. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first sid

Problems solved by technology

Glaucoma is frequently, but not always, accompanied by abnormally high intraocular pressure.
However, in many glaucoma patients, drainage of the aqueous humor through the trabecular meshwork is impaired, thereby causing the pressure of aqueous hu

Embodiment Construction

[0038] Turning now to FIG. 1, a device in accordance with the present invention for cutting and / or ablating tissue, for example, tissue of an eye during a goniectomy procedure, is shown generally at 10. The device 10 generally comprises an elongate handpiece or probe having a distal end having a tissue cutting or ablating apparatus 4 disposed generally within the distal end or distal portion of the probe 3. The tissue cutting or ablating apparatus 4 may be a suitable mechanism designed to cut, ablate, cauterize, sever and / or remove tissue from a target region, for example, from a surgical site. The device 10 may be part of a larger surgical system 11, for example, the device 10 may be structured and adapted to be operatively connectable to a separate apparatus, for example a surgical control console 70 for controlling and powering operation of various functions of the device during a surgical procedure. Examples of surgical consoles that may be suitable include but are not limited t...

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.

Description

RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Patent Application No. 60 / 477,258 filed on Jun. 10, 2003, the entirety of which is expressly incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] A. Symptoms and Etiology of Glaucoma [0003] The term “glaucoma” refers generally to a group of diseases which cause progressive damage to the optic nerve and resultant optical field defects, vision loss and, in some cases, blindness. Glaucoma is frequently, but not always, accompanied by abnormally high intraocular pressure. Aqueous humor is continually produced by cells of the ciliary body and such aqueous humor fills the anterior chamber of the eye. Excess aqueous humor normally drains from the anterior chamber of the eye, through a structure known as the trabecular meshwork and then out of the eye through a series of drainage tubules. However, in many glaucoma patients, drainage of the aqueous humor through the trabecular meshwork is impaired...
