Abstract: A disc brake caliper with auxiliary system to cool brake fluid for use in a high performance automobile includes a brake caliper (12) and a cooling system (14). The brake caliper (12) has a housing (34), a first conduit (60), and a second conduit (74). The first conduit (60) conveys a hydraulic fluid to first and second bores (48, 50), whereby pistons received within the bores (48, 50) may be activated to press friction pads (22, 26) against a rotor (16) and provide a braking action. The second conduit (74) conveys a coolant through the housing (34) to a region proximal the first conduit (60). The cooling system (14) comprises the second conduit (74), a pump (94), and a radiator (96) connected in series via connective plumbing (92) to form a fluid circuit.

Abstract: An apparatus (10) for preparing and administering a dose of a fluid mixture for injection into body tissue includes a syringe assembly (20), a valve (30), a vessel (60) containing a pressurized fluid, and an infusion cannula (70). The valve (30) has a first passageway (98), a second passageway (99), a third passageway (100), and a fluid flow director (96). The fluid flow director (96) selectively directs fluid flow between any two of the passageways, and simultaneously shuts off flow to the third. The first passageway (98) is connected to a fluid receiving reservoir with the syringe assembly (20), the second passageway is removably connected to the infusion cannula (70), and the third passageway (100) is connected to the vessel (60).

Abstract: The illuminated tissue manipulator includes a handpiece and an elongated rigid probe including a tubular body having an outside dimension suitable for insertion through an opening in a patient's eye and terminating in a forward edge extending around a substantial portion of the outer periphery generally perpendicular to the longitudinal axis of the probe body. The probe body has an integral, narrow tissue manipulating tool which extends longitudinally and outwardly beyond such forward edge. An elongated fiber optic light-conducting member extends through the handpiece and the probe body. One end of the light-conducting member extends in a plane generally perpendicular to the longitudinal axis of the probe body and is disposed adjacent the forward edge of the probe body and the other end is remote from the handpiece and includes an optical connector which is connected to a light source.

Abstract: The retinal tack includes a generally conical, sharply pointed forward end portion for piercing through the retina, choroid, and sclera, an elongated, generally cylindrical retaining portion having a longitudinal dimension approximating the thickness of a patient's retina, choroid, and sclera and including one or more peripheral grooves for receiving sclera tissue displaced during insertion of the forward end portion, and an enlarged head having a radially extending flange portion for engaging the retina in the area of the opening formed in the retina. The tack is carried in the tip of a tubular probe selectively connected in fluid communication with sources of negative and positive pressures and the head includes a seat portion which sealingly engages a complementary seat in the probe tip when a negative pressure is applied to the probe.

Abstract: The fluid infusion device includes a primary and an auxiliary fluid pump capable of providing a substantially continuous flow of a fluid, such as air. A pressure regulator driven by a reversible electric motor regulates the air pressure and the flow of pressurized air through an disposable air delivery unit, consisting of a millipore, bacterial static filter and a tube removably connected to an air outlet is controlled by a normally closed, solenoid-operated infusion valve. Separate pressure transducers detect the pump output pressure, the regulator outlet or preset pressure, and the infusion pressure downstream of the infusion valve when it is open.
