Abstract: The invention provides a medical device having a thermister for temperature measurement, irrigation/aspiration ports for fluid exchange and application of therapeutic modalities, a pressure manometer for pressure measurement, and an external system for control of temperature, pressure, and flow rate. When applied to the eye, eyelid and orbit, this device can be used in hypothermia or hyperthermia applications, the control of intraocular pressure (IOP), and the application of treatment modalities. Methods of using the device in treating patients suffering from central retinal artery occlusion, anterior optic nerve disease, pathology of the choroid and retina including the macula, inflammation of the eye including the vitreous and anterior segment, glaucoma, inflammation and/or infections of the anterior and/or posterior segment of the eye, treatment before/during/after surgery of the eye, and the application of treatment modalities including iontophoresis through a semi-permeable membrane are described.

Abstract: A tennis racquet apparatus comprises a handle integral with a neck and a frame, the frame strung to define a face of the racquet. A weighting device engaged with or within the frame, neck or handle, is in a position for urging the face of the racquet into a vertical attitude relative to a ground surface when the handle of the racquet is near horizontal. The weighting device may be a solid, a granulate or a liquid and of such consistency as to flow to the lowest point of the racquet.
