  • Patent number: 9387492
    Abstract: An apparatus for dispensing droplets comprises a dispensing tip with an orifice having a cross sectional area in the range of 0.00002 mm2 to 0.03 mm2. An actuator assembly comprising an actuator element engages with and disengage from the tip and, when engaged, couples acoustic energy to liquid in the tip to expel the liquid through the orifice as a droplet. The actuator assembly includes one or more piezo elements, which may be in the form of piezo stacks. In some embodiments, the actuator assembly comprises a plurality of jaws adapted to move to engage with the dispensing tip for dispensing. This allows side loading of the tip followed by movement of the actuator assembly to engage the tip.

  • Patent number: 9204913
    Abstract: A bone cement delivery system for vertebroplasty with a cannula having a rigid metal tubular inner wall surrounding a central conduit with a distal outlet port, a rigid metal tubular outer wall extending around the inner wall to define a peripheral conduit with a distal inlet port in the form of fenestrations defined in the tubular outer wall, unobstructed and directly exposed to an environment of the delivery system, a proximal inlet port in communication with the central conduit and a proximal outlet port in communication with the peripheral conduit. A vacuum pump communicating with the proximal outlet port of the peripheral conduit applies a pressure in the range of 10 to 100 KPa to create a pressure gradient between the central conduit and the peripheral conduit to produce a difference in flow rate between the conduits guiding the displacement of bone fluid and the flow of cement.

  • Patent number: 9168335
    Abstract: A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes.

  • Patent number: 9114207
    Abstract: A syringe plunger driver system capable of capturing syringes of widely varying sizes comprises a pair of asymmetric plunger retainer arms pivotally mounted to a plunger driver. The system includes a low profile driver having a length that exceeds its width so that it may be mounted adjacent control modules and other operational modules. The arms are biased toward each other and one arm is longer than the other with a notch on an inside edge to receive the tip of the shorter arm when capturing small syringe flanges. A rotation knob mounted to the front surface of the low profile driver forces the arms apart when rotated to a first rotation position. A force sensor is mounted in the driver to detect occlusions in the fluid line. A processor monitors the force sensed by the force sensor and provides an alarm if the force exceeds a threshold.
