Abstract: A wound sealing sleeve for use with a goniotomy device has a hollow body with an open end by which the sleeve is attachable to a handle and an open tip through which a shaft is passed. One or more optional ports are formed in the sleeve to provide variable fluid paths. The port or ports may differ in size, shape and positioning on the sleeve. The wound sealing sleeve may be affixed to a handle by threads, a friction fit, glue, or mechanically fastened. The wound sealing sleeve is able to be deformed slightly in order to match the shape or contour of the eye incision to prevent leakage between the exterior surface of the wound sealing sleeve and the surgical incision.

Abstract: A microsurgical device contains a fluidics control containing multiple controlled fluidics paths that enable bi-directional flow and fluid separation or mixing. The fluidics control has a housing including a separable end piece. The housing may serve as a mixing chamber that enables mixing multiple fluids or drugs or diluting a concentrated drug to provide varying drug concentration. The end piece may include one or more ports that may be connected to an aspiration pump or variable substance chambers through plastic tubing. The end piece may be rotationally or frictionally connected to the housing and partially enclosed by the housing. The microsurgical device further includes a fluid control element configured to regulate the fluid flow into or out of the device, or a combination thereof.
