Abstract: A fluid sensor apparatus for monitoring fluid in a container. The fluid sensor apparatus comprises a housing having an upper hook extending from a top thereof to allow the housing to be suspended. A lower hook is telescopically received in the housing and extends from a bottom thereof. The lower hook is adapted for suspending a fluid container therefrom. The lower hook is movable relative to the housing. A cam member is located inside the housing and is movable relative thereto. The cam member is coupled to an upper end of the lower hook. The cam member has a stepped gradation. A biasing member is coupled between a lower shoulder of the cam member and the housing. The biasing member is adapted to apply a force against the cam member to cause the cam member to be biased upward relative to the housing to an upper position. A switch is coupled to the housing and has an actuator located in relation to the stepped gradation of the cam member.

Abstract: The present invention is directed to a device for producing a shock wave to impact an object that includes a transfer member. The device has a voice coil assembly including a permanent magnet and a bobbin member, wherein the permanent magnet provides a first magnetic field. A hammer is attached with the bobbin member; and a coil is operatively attached to the bobbin member, wherein when a voltage is applied to the coil a second magnetic field is generated that opposes the first magnetic field and thereby propels the hammer to contact the transfer member to cause a shock wave to travel along the transfer member.

Abstract: An irrigation apparatus and a method of use for delivering fluid flow to a surgical site. The irrigation apparatus includes a refillable fluid reservoir with an inlet for receiving fluid via first tubing from a fluid source, and an outlet for second tubing leading to a surgical site. A sensor monitors the fluid contained within the reservoir. The sensor sends a signal to a controller, which operates a pump. The pump transports fluid from the fluid source to the refillable reservoir via the first tubing.

Abstract: A tubing set and method for use with a system for providing pressurized fluid from a fluid source to a surgical site. The system includes a fluid source, a length of flexible tubing having one end connected to the fluid source and another end connected to a surgical instrument, and a peristaltic type pump into which a middle portion of flexible tubing is positioned so that the peristaltic type pump can pump fluid from the source to the surgical instrument by bearing on the exterior of the tubing. The improved tubing set also includes a by-pass section of tubing connected between the tubing inlet and the tubing outlet in parallel with the middle portion of the flexible tubing. The by-pass section provides pressure relief to the system so that pressure in the tubing will not build up distally of the location of the peristaltic pump.

Abstract: A tubing set for connecting a source of irrigating fluid to an intraoperative surgical instrument having a fluid delivery passage therein. The tubing set includes a first section having an inlet for connection to the source of irrigating fluid, a second section having an outlet for connection to the intraoperative medical instrument, and a pump connected between the first section and the second section. A valve is located between the inlet and the outlet and restricts flow so that flow is in a direction from the inlet toward the outlet. The tubing set can deliver a continuous flow or trickle of fluid from the source of irrigating fluid to the medical instrument and can deliver a bolus of fluid to the surgical instrument upon operation of the pump.
