  • Patent number: 6835186
    Abstract: This invention provides a medical device for delivering volumetric quantities of a first and a second biochemically reactive fluid in which separate MBUs atomize the fluids. The device of the present invention includes a fluid delivery device for laparoscopically delivering fluids having two feed conduits for delivering fluid to feed ports of the mechanical breakup units, the mechanical breakup units having two feed ports for receiving fluid from the feed conduits and directing such fluid into spin chambers and funneling portions having a sloped sidewall for directing fluid from the spin chambers through an exit port. The device is suitably dimensioned for creating a spray of two fluids with different viscosities such as fibrinogen and thrombin in such a manner that the thrombin spray cone encompasses the fibrinogen spray cone at a distance of about one inch from the exit port with a 0.5 cc/second flow rate to avoid depositing unreacted fibrinogen on a surface.

  • Publication number: 20040024353
    Abstract: An applicator gun for spraying a medically useful multiple component fluid to an area of interest. The handheld applicator gun functionally receives a commercially available or standardized multi-syringe applicator, and dispenses fluid from the multi-syringe applicator in a controllable manner. The handheld applicator gun further includes a return stop and a dispensing stop to limit the force exerted on the multi-syringe applicator.

  • Patent number: 5615678
    Abstract: An integral yoke/transducer connector has built-in probe switches for detecting when a transducer probe has been removed from its yoke. Based on the status of the probe switch and other feedback information, a system controller activates the out-of-holder probe if it has priority. In this manner, a probe can be automatically activated when it is lifted out of its yoke, thereby eliminating the need to trace a desired probe to its connector/port via the cable. Once a probe/port is auto-selected, it remains the only active probe/port until the probe is placed back in the yoke (or its transducer connector is disconnected from the port on the imaging unit). Placement of the probe in its corresponding yoke opens the probe switch which is built into the yoke/connector assembly.
