Glaucoma drainage shunts and methods of use
ActiveUS20100114006A1Reducing heightened intraocular pressureEasy outflowLaser surgeryWound drainsVisibilityGlaucoma
A method of treating glaucoma in an eye utilizing an implanted shunt having an elastomeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera of the eye with an outflow end of the elastomeric drainage tube open to an outer surface of the plate. An inflow end of the drainage tube tunnels through the sclera and cornea to the anterior chamber of the eye. The drainage tube collapses upon initial insertion within an incision in the selera and cornea, or at a kink on the outside of the incision, but has sufficient resiliency to restore its patency over time. The effect is a flow restrictor that regulates outflow from the eye until a scar tissue bleb forms around the plate of the slunt. The plate desirably has a peripheral ridge and a large number of fenestrations, and a longer suturing tab extending from one side of the plate to enhance visibility and accessibility when suturing the shunt to the selera.

The apparatus of the present invention stretches the carpal ligament and the flexor retinaculum, as well as the superficial structures and muscles of the hand, in a safe manner under precise control of the patient or a healthcare professional. A first embodiment of the inventive apparatus includes a housing for receiving the patient's hand with a bottom portion having a first pressure element positioned to contact the hypothenar region of the patient's hand and a second pressure element positioned to contact the thenar region of the patient's hand, and a top portion having a central longitudinal pressure element positioned to contact the central longitudinal dorsal region of the patient's hand. The first and second pressure elements are connected to active pressure sources (or source), such that when the hand is inserted into the housing, the first and second pressure elements are activated and exert pressure on the respective hypothenar and thenar regions of the hand while the central dorsal portion of the hand presses against the third pressure element. This forces the thenar and hypothenar regions apart thus advantageously stretching the carpal ligament, the flexor retinaculum, and superficial structures and muscles of the hand. In another embodiment of the present invention, the third pressure element is also connected to an active pressure source, such that active pressure is applied to the central dorsal region of the hand, while the first and second pressure elements apply pressure to the hypothenar and thenar regions of the hand.

Each of the top surface and bottom surface have a large rounded apex to maximize the area of the blade. Each surface also has concave regions that may form the cutting edges. Advancing the MVR trocar blade into tissue causes the tissue to contact the apexes of the top and bottom surfaces. The apexes draw the tissue into contact with the cutting edges. The cutting edges incise the tissue such that the incision is sized to accommodate a trocar cannula. The geometry of the top surface and bottom surface ensure that the features of the blade do not protrude radially outside of the diametral envelope of the shaft.
