Abstract: An intraocular drainage device may include a monolithic silicone body having a flap, a rigid bottom plate having a portion configured to contact a corresponding portion of the flap, and a tube having a proximal end disposed between the flap and the rigid bottom plate. The corresponding portion of the flap may be configured to separate from the portion of the rigid bottom plate responsive to a fluid pressure in aqueous humor received from the tube. A plurality of parallel microgrooves may be formed on one or more portions of one or more outer surfaces of the intraocular drainage device.

Abstract: A medical device includes a valve comprising a pair of plates holding in tension a membrane folded over to form a chamber with an elongated, slit-like opening along adjoining edges. An inlet tube in communication with the chamber extends outwardly. The valve is installed in a pocket of a flexible distribution plate having ridges emanating from the pocket in a radial pattern. The device is implanted in the globe of the eye of a patient between the rectus muscles.

Abstract: Disclosed is a medical device for draining fluid which includes a shell made of a flexible, resilient material. The shell has an aerofoil-like shape with opposed ends and an anterior cavity and a posterior cavity separated by a partition wall. An inlet tube has a first end in communication with the fluid and a second end in communication with anterior cavity and an outlet tube has a first end in communication the posterior cavity and a second end from which the fluid is drained. A one-way directional flow valve is housed within the posterior cavity and it has an inlet end connected to the partition wall which is in communication with the anterior cavity and an outlet end in communication with the posterior cavity.

Abstract: Disclosed is a medical device comprising an external, flexible shell forming a fluid chamber reservoir and housing a valve, having a folded membrane which forms a chamber with a slit-like opening. The inlet tube in communication with the chamber extends outwardly through an opening in the shell. The inlet tube has a free end with holes and rigid fins. The free end of the inlet tube in communication with abdomen. There is an outlet tube in communication with the reservoir. The outlet tube has a free end with holes. The free end of the outlet tube is in communication with the jugular vein of a patient. Also disclosed is a method of using this device to treat ascites.

Abstract: Disclosed is a medical device comprising an external, flexible shell forming a fluid reservoir and housing a non-obstructive, self-regulating valve, having a folded membrane which forms a slit-like opening in a chamber. An inlet tube in communication with the chamber through an aperture in the membrane extends outwardly through an opening in the shell. The free end of the inlet tube, including holes, is in communication with the brain or cranial vault. There is an outlet tube in communication with the reservoir. The free end of the outlet tube, also including holes, is in communication with either the heart or the abdomen. If the outlet tube is in communication with the abdomen the preferred configuration of the free end includes rigid fins. Also disclosed is a method of using this device to treat hydrocephalus and a process for making the device.

Abstract: A medical device includes a one-way flow valve in communication with fluid to be drained. The valve is connected to a primary distribution plate which has a raised perimeter with at least one opening in the perimeter. There is a secondary distribution plate having a raised perimeter with at least one opening in the perimeter. At least one pair of plugs, each having a central passageway, are inserted into the openings in the perimeters of the primary and secondary distribution plates, and an connecting tube places the primary and secondary distribution plates in fluid communication with each other. The tube is sized to fit inside the central passageway of the plugs, with the connecting tube having opposed ends, each end inserted to the passageway in the plugs. The distance between the plugs is adjusted by sliding the plugs along the length of the connecting tube.
