  • Method for utilizing temperature to determine a battery state
    Patent number: 7348763
    Abstract: A method for determining the state of a battery, or battery pack, that is independent of the type of battery technology under test. The method employs one or more charging and discharging cycles, and measures one or more parameters of battery voltage, temperature, charging time, and charging cycle counts to produce a test value that is compared to empirical data. Based on the comparison, the state is determined, for example, on a pass/fail basis. The method may be embodied as instructions stored in memory and implemented by means of a microprocessor coupled to the memory. In another embodiment, the empirical data is stored within another memory located internal to the battery pack under test.

  • Peristaltic irrigation pump system
    Patent number: 7273359
    Abstract: A peristaltic pump tubing system for use with a peristaltic pump roller assembly in a surgical procedure. The system comprises a uniquely shaped disposable cassette for retaining tubing to be used during the procedure and a uniquely shaped cassette receiving station situated adjacent the roller assembly. The cassette comprises a frame for holding the tube in a loop shape for engagement with the peristaltic rollers. The frame supports a one-sided pressure transducer to indicate the pressure within the tube. The cassette receiving station includes a sensor for engaging the one-sided pressure transducer and is situated adjacent the rollers of the peristaltic pump on the pump housing. A retaining bracket cooperates with the inherent resiliency of the tubing loop to hold the tubing in place against the rollers.

  • Electrosurgical device with adhesive-free insulating piece and method of making same
    Patent number: 7244256
    Abstract: An electrosurgical device having an electrode and an insulating piece such as a ceramic insulator is disclosed. The electrode includes an active surface for ablating and/or coagulating tissue in an electrosurgical procedure. The insulating piece surrounds the active surface and provides a barrier for the intense heat created during ablation. The insulating piece is also electrically nonconductive to prevent unwanted discharge of energy. Electrode has a retaining ledge configured to engage a lip formed on the insulating ring. The insulating ring is secured to the electrosurgical device by connecting the electrode to an electrode seat and capturing the insulating piece in between. The electrode can be connected to the electrode seat by projection welding. The insulating piece is connected to the electrode without the use of an adhesive.

  • Dilator for bone tunnels
    Patent number: 7211098
    Abstract: A tool for dilating tunnels in bone, in order to compact the cancellous bone around the tunnel and providing better holding for interference screws and the like, comprises a plurality of elongated segments mounted for radial motion with respect to an axis of elongation. When actuated, the segments move radially outwardly, parallel to the axis of elongation, compacting the bone.

  • Soft tissue anchor
    Patent number: 7189238
    Abstract: A soft tissue anchor is provided for attaching soft tissue to bone. The anchor is useful generally throughout the body where soft tissue needs to be anchored to bone. It is particularly useful for reattaching separated tissues adjacent to an articular joint such as the hip, knee, or shoulder. For example it is well suited for reattaching labral tissue that has become separated from the glenoid rim adjacent a shoulder joint.

  • Electrosurgical ablator with integrated aspirator lumen and method of making same
    Patent number: 7150746
    Abstract: Electrosurgical devices for ablating tissue and methods of making the same are disclosed. The electrosurgical devices include an electrode with a lumen for aspirating gasses and debris produced during surgery. The electrode also includes a plurality of upper active edges for ablating tissue in an electrosurgical procedure. The upper active electrodes are spaced apart to form a filter that filters out large tissue particles from being aspirated into the lumen. The upper active edges ablate the large particles to form particles that can pass into the lumen. A lower active edge is formed at the terminal end of the lumen for ablating tissue being aspirated into the lumen. The lower active edge prevent tissue particles from occluding the opening to the lumen.

  • Toggle anchor and tool for insertion thereof
    Patent number: 7041120
    Abstract: A method for delivering an anchor member into biological tissue comprising: accessing and preparing an insertion site for the anchor member; holding the anchor member at a distal end of an insertion tool; providing the anchor member to the site with the insertion tool; causing a rotational movement of the anchor member about a first axis perpendicular to a longitudinal axis of the insertion tool whereby the anchor member engages the tissue at the site by moving about the first axis from a first position substantially aligned with the longitudinal axis to a second position at an angle relative to the longitudinal axis; and withdrawing the insertion tool from the site, leaving the anchor member secured at the site.

  • Method and apparatus for delivering a stent into a body lumen
    Patent number: 6991646
    Abstract: Method and apparatus for delivering a stent, including, but not limited to, a self expanding stent, into a body lumen. The apparatus comprises an outer tube having a proximal end and a distal end and sized to hold a stent therein in a radially constricted condition, an inner tube within the outer tube and having a proximal end and a distal end, and a holding element comprising one or more inflatable balloons carried on the inner tube at the location of the loaded stent. The balloon can be inflated prior to the procedure so that the balloon presses against the inner surface of the outer tube trapping the stent in its longitudinal position between the inner and outer tubes. Accordingly, the outer tube can be slid proximally to release the stent or distally to retract the stent back into the delivery device without the stent inadvertently sliding.
