Devices and methods useable for forming opening in trabecular meshwork of mammalian eyes.

Devices, systems and methods for minimally invasive glaucoma surgery

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.

Devices and methods useable for treatment of glaucoma and other surgical procedures

A dual blade device and method useable for performing an ab interno procedure within a human eye to remove a strip of trabecular meshwork tissue.

Dual blade ophthalmologic surgery device

A surgical device, system and method for forming opening in the trabecular meshwork of eyes to facilitate drainage of aqueous humor and resultant lowering of intraocular pressure are provided. The device comprises a shaft and a distal member or foot on a distal end of the shaft. The distal member or foot may have a forward tip, a right edge, a left edge and a transversely concave depression, cavity or space between the right and left edges. The distal member is insertable into Schlemm's canal of an eye and thereafter advanceable through Schlemm's canal such that trabecular meshwork tissue will be cut by the right and left edges.

Devices useable for treatment of glaucoma and other surgical procedures

A dual blade device comprising an elongate probe having first and lateral second cutting edges and a blunt protruding distal tip, useable for performing an ab interno procedure to remove a strip of trabecular meshwork tissue from a human eye.

Methods and devices for cutting strips of tissue from masses of tissue inside or outside of the bodies of human or animal subjects. The device generally comprises a) an elongate cutting tube that has a distal end and a lumen that opens through an opening in the distal end and b) first and second cutting edges formed on generally opposite edges of the distal end of the cutting tube and separated by a distance D. The device is advanced through tissue to cut a strip of tissue of approximate width W. Width W is approximaely equal to distance D.

Tubular cutter device and methods for cutting and removing strips of tissue from the body of a patient

Methods and devices for cutting or coagulating. A device comprises a) an elongate member having a distal end, b) at least one foot member extending from the distal end of the elongate member, said foot member having a upper surface and a lower surface, c) an electrically and thermally insulating covering formed on at least the lower surface of the foot member and d) at least one electrode on the upper surface of the foot member. In operation, the at least one electrode is energized so as to cause cutting or coagulation of tissue located above the upper surface(s) of the foot member(s) while not causing substantial damage to tissue located below the lower surface(s) of the foot member(s).

Electrosurgical devices and methods for selective cutting of tissue

Methods and apparatus for qualitatively or quantitatively determining one or more analytes in matrices such as foods, biological fluids, etc. An embodiment for determination of a single analyte comprises a sample receiving vessel, a first membrane and a reagent-containing well. The prepared sample passes through the first membrane whereby extraneous matter is removed, and a filtrate enters the reagent-containing well to provide a filtrate-reagent admixture from which the analyte may be determined. An embodiment for determination for multiple analytes includes one or more additional membranes in series with the first membrane, each such additional membrane being operative to capture one or more analytes. Each of the additional analytes may then be eluted from the membrane upon which it has been captured, into a separate reagent-containing well to provide eluant-reagent admixture from which each desired analyte may be determined. Formulations for preparation additives are also included. Additionally, there's provided an embodiment of above-described invention for determination of an analyte which is present in a matrix at low (e.g., sub-detectable) levels, wherein the filter of the apparatus is utilized to capture and concentrate the analyte, to provide a filtrate-reagent admixture wherein the analyte is present at detectable concentration.
