Patent number: 5885270Abstract: A method and apparatus for automatically transferring a predetermined quantity of a sterile liquid to a vial containing a dry medicament for hydrating the medicament and then transferring the hydrated medicament to a container. To hydrate the medicament, a needle is positioned through a vial septum of the vial and an artificial sensor senses when the needle has been positioned through the vial septum and actuates a pump to transfer a predetermined quantity of sterile liquid into the vial. The needle is then removed from the vial septum and the vial is shaken to mix the liquid and medicament. To transfer the hydrated medicament to a container, another needle is positioned through the vial septum. An artificial sensor senses when the needle has been positioned through the vial septum and actuates the pump to transfer the hydrated medicament to the container.Type: GrantFiled: February 5, 1997Date of Patent: March 23, 1999Assignee: Smith Kline Beecham CorporationInventors: Jose A.

Patent number: 5885240Abstract: A vessel (20) which is divided into compartments (22, 24) receives medical and biological fluid wastes through inlet fitting (12, 14). As the fluid is received, air in the vessel is displaced and is discharged through a vent line (32), either to atmosphere or to a vacuum source. When a level sensor (34) senses that a level of fluid in the vessel is approaching a preselected maximum, a control circuit (40) closes a valve (30) in the vent line, blocking the discharge of air from the vessel and creating a backpressure that stops the receipt of further fluid. Tubing connected to the fittings (12, 14) is disconnected from the patient or other source of fluid and a valve (64) is manually opened to vent the vessel, allowing any residual fluid in the tubing to be drained into the vessel. A drain valve (74) is opened to drain the vessel and the cleaning cycle is commenced.Type: GrantFiled: June 18, 1997Date of Patent: March 23, 1999Assignee: Steris CorporationInventors: John R. Bradbury, Richard L. Terry, Clayton W. Spangler

Patent number: 5882325Abstract: In a heart-lung machine, blood is defoamed without the use of defoaming chemicals by passing blood between parallel insulated electrodes whose electric field orients the blood protein molecules to break up the foam bubbles. The blood then passes into the venous reservoir through a bubble screen which traps any remaining bubbles.Type: GrantFiled: July 28, 1997Date of Patent: March 16, 1999Assignee: Medtronic, Inc.Inventor: Sean D. Plunkett

Patent number: 5882327Abstract: An implantable ocular device to decrease intraocular pressure by draining aqueous humor from the anterior chamber of the eye into an extraocular space above the sclera and below the conjunctiva and Tenon's layers. The device includes a conduit attached to an episcleral drainage plate having a porous posterior surface for cellular ingrowth and attachment by the sclera. The distal end of the conduit is inserted into the anterior chamber and protrudes out of the limbal/scleral junction. A portion of the outer surface of the conduit adjacent to the plate has a porous ingrowth surface area to enhance anchoring of the conduit to the surrounding extraocular tissues. The plate has a smooth anterior surface and a porous posterior surface. This device uses porous surfaces to enhance cellular infiltration and ingrowth to increase apposition with surrounding tissues, decrease micromovement of the implant, and thereby decrease the fibrous capsule formation surrounding the episcleral plate.Type: GrantFiled: April 17, 1997Date of Patent: March 16, 1999Inventor: Jean T. Jacob

Patent number: 5879321Abstract: A shunt includes a tubular body having first and second legs at a proximal end and a third leg at a distal end. A fluid distensible balloon and cooperating insufflation conduit are carried on the tubular body. The first leg of the tubular body includes a longitudinal slit for receiving the second leg whereby the first and second legs may be positioned substantially coaxial so as to allow easier introduction of the shunt into the blood vessel of a patient. Similarly, the second leg having a longitudinally slit for receiving a portion of the cooperating insufflation conduit and also holding it in a coaxial position. A leader tube with a blunt atraumatic tip is received over the proximal end of the tubular body to further aid in the introduction of the shunt.Type: GrantFiled: January 22, 1997Date of Patent: March 9, 1999Assignee: The University of Kentucky Research FoundationInventor: Bradley B.

Patent number: 5879320Abstract: The present invention is an implantable vascular device which has the ability to open and close without the formation of thrombi. The device comprises at least one shunt which maintains a valve system. This shunt is surgically grafted to a blood line for enabling fluid flow through the shunt when the valve system is in an opened state. This will provide a device which is well suited for use in hemodialysis because the shunt can be opened for hemodialysis and closed when not in use. The destructive problems associated with the high flow states is limited only to the short time interval of the hemodialysis.Type: GrantFiled: December 23, 1996Date of Patent: March 9, 1999Inventor: Craig Richard Cazenave
