  • Patent number: 9795365
    Abstract: An apparatus for use with a minimally invasive medical procedure into human breast tissue includes a cannula and an obturator. The cannula includes an open distal end, a lateral opening proximate to the open distal end, and a longitudinal lumen communicating with the lateral opening and the open distal end. The lumen has a non-circular cross-section. The obturator is sized for insertion into the cannula. The obturator has a distal end extending from the open distal end of the cannula when the obturator is inserted fully into the cannula. The obturator has a recess proximate of the distal end of the obturator. The recess is positioned along a portion of the length of the obturator to align with the lateral opening of the cannula when the obturator is inserted fully into the cannula.

  • Patent number: 9638770
    Abstract: An obturator as part of a biopsy system enhances use with Magnetic Resonance Imaging (MRI) by indicating location of a side aperture in an encompassing cannula. The cannula (e.g., detached probe, sleeve sized to receive a core biopsy probe) includes a side aperture for taking a tissue sample. When the obturator is inserted in lieu of the biopsy device into the cannula, a notch formed in a shaft of the obturator corresponds to the side aperture. A dugout trough into the notch may further accept aqueous material to further accentuate the side aperture. In addition, a series of dimensionally varied apertures (e.g., wells, slats) that communicate through a lateral surface of the shaft and that are proximal to the side aperture receive an aqueous material to accentuate visibility in an MRI image, even in a skewed MRI slice through the cannula/obturator.

  • Patent number: 8789740
    Abstract: A surgical stapling instrument including a selectively actuatable cutting member. The stapling instrument may be used as a surgical stapler without cutting tissue or, if desired, the surgeon may selectively actuate the cutting member to cut tissue as the staples are being deployed and formed. A stapling instrument can include an actuator knob that has at least one pusher bar attached thereto. Advancement of the actuator knob in a distal direction causes the pusher bars to apply a firing motion to the staples contained within a staple cartridge supported within the stapling instrument. A knife bar may be selectively coupleable to the actuator knob by a selector switch that is movable from an actuated position wherein movement of the actuator knob in the distal direction advances the knife bar which has a cutting blade portion to advance between rows of staples in the staple cartridge to an unactuated position wherein movement of the actuator knob advances the pusher bars without advancing the knife bar.

  • Patent number: 8727964
    Abstract: An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. The elongated member has a compressible ventral surface and a substantially rigid dorsal periphery, wherein the elongated member includes a fluid bladder positioned along the ventral surface. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. Alternate embodiments are also disclosed.

  • Patent number: 8066167
    Abstract: Circular stapling instruments for cutting and applying one or more surgical staples to tissue are disclosed. The instruments include various forms of anvil locking systems designed to selectively prevent the anvil from moving axially relative to the stapling head of the stapling instrument. One embodiment employs an elongated gear rack that is selectively engagable with locking gears to prevent axial motion of the elongated gear rack and an adjustment shaft used to axially position the anvil. Other embodiments employ a gear assembly that cooperates with the elongated gear rack. A locking member is movably supported by a handle assembly that houses the gear assembly and elongated gear rack. The locking member is configured for selective meshing engagement with the gear assembly to ultimately prevent axial movement of the gear rack and adjustment shaft.
