Abstract: A method and system for infusing and monitoring a tethered laboratory animal includes a platform suitable for carrying the laboratory animal. A tether assembly includes a flexible conduit for connecting to the animal and a tether for tethering the animal. A torque sensor detects a motion of the animal and drives the tether assembly in response to the detected motion of the animal, and thereby reduces the torque on the animal. The platform is driven in a direction opposite to the tether assembly so that it appears to be stationary when the tether assembly is driven in response to a detected motion of the animal.

Abstract: A pump and a method for pumping liquid or fluid through a pair of resilient tubes includes a pushing mechanism which partially compresses the tubes in a balanced, alternating, rocking manner. The resilient tubes are held in a parallel relationship. The pushing mechanism alternately compresses the tubes. As one of the two parallel tubes is compressed, fluid is pumped out of the tube and at the same time fluid is drawn into the second tube as the latter tube resumes its original shape. The resilience of both tubes also is used to assist the pumping action in a balanced fashion, thereby providing a pump that has low power consumption and is lightweight.

Abstract: A pump and a method for pumping liquid or fluid through a pair resilient es includes a shuttle block which partially compresses the tubes in a balanced, alternating manner. The resilient tubes are held in a parallel relationship with a predetermined space defined therebetween. Within the predetermined space, a shuttle block is oscillated along the linear axis to partially compress the tubes in an alternating fashion. As one of the two parallel tubes is compressed, fluid is pumped out of the tube and at the same time fluid is drawn into the second tube as the latter tube resumes its original shape. The resilience of both tubes also is used to assist the pumping action in a balanced fashion, thereby providing a pump that has low power consumption and is lightweight.

Abstract: A glaucoma needle is provided which combines goniopuncture with cautery for perpetuating a fistula in the sclera of the eye. The needle comprises a hollow casing forming a point, electrically activated thermal means which generate a thermal heat band on the casing, the band extending radially from the center of the casing and connector means for attaching the thermal means to a power supply. In the method of this invention the glaucoma needle is passed through the clear cornea, across the anterior chamber to the opposite anterior chamber angle and then out at the limbus to form a goniopuncture which is cauterized by the application of heat from the thermal heat zone created by the needle.
