  • Publication number: 20190175241
    Abstract: A control module for a powered surgical tool. The module includes a shell. Internal to the shell is a circuit for controlling the power generating unit of the tool with which the module is associated. Conductive pins extend through the shell to provide electrical connections to the components within the shell. Active seals are disposed around the conductors and the inner walls of the shell that define the openings in which the pins are seated. Each active seal include an inner and outer skirt. A biasing component disposed between the skirts urges the inner skirt against the section of the conductive pin seated in the opening. The biasing component also urges the outer skirt against the adjacent opening-defining inner wall of the shell. The active seal functions as a barrier between the conductive pin and the adjacent inner wall of the shell.

  • Patent number: 10076340
    Abstract: A battery and control module to which a powered surgical tool is releasably attached. Internal to the module there is: a cell for energizing the tool; a sensor for monitoring an operational state of the tool; a sensor for monitoring a trigger external to the module; and a control circuit. Based on the signals output by the sensors, the control circuit selectively applies energization signals from the cell to the power generating unit internal to the surgical tool. In some versions of the invention, the trigger is attached to the module.

  • Patent number: 8016744
    Abstract: An external pressure sensing system may include an attachment for a syringe. The attachment may comprise a connector positioned between the barrel and the needle of the syringe. A pressure sensor may be in fluid communication with the connector, such that the pressure sensor may sense the pressure of fluid within the connector as the syringe is used to add fluid to or withdraw fluid from an injection port. Where an injection port is a component of an adjustable fluid-based gastric band system, pressure data obtained with the pressure sensor may be indicative of the pressure of fluid within the gastric band. The pressure sensor may communicate pressure data to a display device. A user may adjust the pressure of fluid within the gastric band using the syringe while viewing the display device for pressure-related readings.

  • Patent number: 8016745
    Abstract: An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the pressure data, and may communicate the pressure data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger.

  • Patent number: 7900800
    Abstract: An apparatus for dispensing a viscous material includes a dispenser body having an inlet and a discharge orifice. A valve element is mounted for movement in the dispenser body between an open position allowing flow from the discharge orifice, and a closed position preventing flow therefrom. An actuator is coupled to the valve element for actuation between the open and closed positions. A heat exchanger having a serpentine passage and a heater is coupled thereto, wherein the heater is in thermal communication with the dispenser body. The passage is configured to deliver the viscous material to the inlet at a uniform temperature. A method of dispensing a viscous material includes positioning a heat exchanger, having a fluid passage and a heater, in thermal communication with the dispenser body, and heating the material flowing through the fluid passage to a uniform temperature prior to delivering it to the inlet.

  • Patent number: 7775966
    Abstract: An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, which may process the pressure data, and may further provide a display to a user including information relating to the processed pressure data. Where the implantable restriction device comprises an adjustable gastric band, the one or more pressure sensors may be located in any number of the following locations: an injection port, an interface between the injection port and a catheter, in a catheter, in-line with a catheter, adjacent to a catheter, in a gastric band, in a gastric band buckle, or elsewhere.

  • Patent number: 7775215
    Abstract: A sense head comprises a plurality of coils and a needle window. The sense head is operable to receive RF signals communicated from a needle target such as an injection port located within a patient. A user interface is configured to visually display an indication to a user relating to the positioning and orientation of the sense head relative to the needle target. The positioning and orientation may be determined based on RF signals received by the coils in the sense head. With the sense head positioned based on information provided through the visual display, the user may insert a needle through the needle window to reach the needle target. The sense head may also receive communications relating to the pressure of fluid in an implanted device. The user interface may further display information relating to the fluid pressure in the implanted device.

  • Patent number: 7727141
    Abstract: An implantable artificial sphincter system provides long-term adjustment via transcutaneous energy transfer (TET), minimizing invasive adjustment through adding or removing fluid via a syringe. An infuser device provides bi-directional fluid transfer via a flexible conduit to a sphincter band, such as a gastric band. Materials are nonferrous and nonmagnetic so as to be magnetic resonance imaging (MRI) safe, being substantially immune to strong magnetic fields and not introducing an electromagnetic interference/compatibility (EMIC) hazard.
