Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: Methods and systems for measuring the pressure of a fluid. A flexible barrier separates the fluid from the pressure receiving surface of a pressure sensing device. The pressure of the fluid is transferred through the flexible barrier to the pressure receiving surface. The flexible barrier may be in abutting juxtaposition with or may be spaced apart from the pressure sensing surface. In either case, the flexible barrier is coupled or held in defined relationship to the pressure sensing surface such that the pressure receiving surface will receive the substantially actual pressure of the fluid even when the pressure of the fluid is less than the ambient atmospheric pressure. Coupling of the flexible barrier to the pressure receiving surface may be achieved by any suitable means, including adhesive or the application of a full or partial vacuum between the flexible barrier and the pressure receiving surface.

Abstract: Apparatus for reducing the size of an object disposed in a generally closed fluid medium includes a handpiece having an axis extending from a housing at a proximal end to a probe at an opposing distal end. A reducer at the distal end of the probe is adapted for insertion into the fluid medium where it is rotatable to reduce in size the object. The reducer is configured to create a fluid flow in the fluid medium so that the handpiece can be maintained laterally and axially stationary while the object is moved by the fluid flow into contact with the reducer. An associated method includes the steps of rotating the rotary member at a speed sufficient to reduce the size of the object, and in a manner to produce a flow of the fluid sufficient to move the object into the rotary member.
