A tissue-implantable fluid-conducting device particularly useful in conducting fluids into and/or away from cavities in the eye. In one embodiment, the invention provides an infusion cannula for delivering fluids to cavities of the eye. The cannula includes a tube having first and second ends and a check valve therebetween for allowing fluid flow only toward said first end. Means is provided at the second end for attaching the cannula to a fluid source, such as a glaucoma alleviation device, a drug infusion device, or other fluid sources. The cannula may also include a compressible reservoir. In another embodiment, the invention relates to a fluid-dissipating device enabling fluid from a source to be delivered to and absorbed by tissue of the eye. The device includes a housing having walls defining an interior cavity, the walls having sufficient rigidity to prevent substantial collapse of the cavity when implanted, orifice means communicating with the cavity to allow fluid transfer from within the cavity to surrounding fluid resorptive tissues, and tube means communicating with the cavity to conduct fluid from a source to the cavity. |
