The rongeur includes a lower shaft and an upper shaft slidable relative to the lower shaft. The lower shaft and upper shaft form a jaw mechanism that can take multiple bites of bone, which can be deposited in a storage cavity formed in the upper shaft. To assist in removing the bone from within the storage cavity, an internal plunger mechanism can be provided that is actuated by a finger hold. In addition, at least portions of the upper shaft are detachable from the lower shaft such that the upper shaft can be thoroughly cleaned and re-used if desired.

  • Patent number: 10327805
    Abstract: A biopsy system with a grid plate used as either a lateral or medial compression plate of a localization fixture used with a breast coil includes a rotatable guide cube that may be inserted into a desired rectangular recess in the grid plate after rotating to position a selected guide hole in the desired spatial orientation. Versions of a guide cube include those rotatable in two axes to provide additional hole positions, angled holes, enlarged circular holes that function with a rotating guide to support a noncircular biopsy instrument cannula (e.g., trocar/sleeve combination, core biopsy probe of a biopsy device) for rotation. A rotating guide may have an unlocked state for easily sliding to a selected longitudinal position thereon. Thereafter, the rotating guide is locked to serve as a positive depth stop (e.g., quarter turn locking elastomeric rings, triangular and scissor clips, and shutter depth stops).

  • Patent number: 10327800
    Abstract: Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm, using a mechanical apparatus, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes formed can be well-tolerated by the skin, and can exhibit shorter healing times and less swelling than conventional resurfacing procedures. The apparatus includes one or more needles adapted to remove a small portion of tissue when inserted into and withdrawn from the skin. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The exemplary method and apparatus can produce cosmetic effects such as increases in collagen content, epidermal thickness, and dermal/epidermal junction undulations in the skin.

  • Patent number: 10278678
    Abstract: A biopsy device for acquiring more than one tissue sample is disclosed. The biopsy device can have at least two tissue engaging elements, where at least one element contains a helical feature. A control mechanism can be used to spin an outer element relative to an internal element, resulting in transport of multiple tissue samples from the mass of tissue to an accessible collection chamber. The outer element may have a sharp distal end which may sever the samples from the mass of tissue. Samples may be stored sequentially in the collection chamber and be removed by the operator.

    Abstract: The present invention relates to apparatuses and methods of using a resection line guide in various medical procedures. A resection line guide may include a first clamp member and a second clamp member configured to be positioned on a first side and a second side generally opposite that of the first side of an anatomical structure, such as, for example, a stomach. The clamp members may be configured to provide a clamping force on the stomach to secure the guide to the stomach. Further, at least one flexible member may be operatively coupled to the clamp members. The flexible member may be configured to be tensioned so as to provide at least a portion of the clamping force on the stomach.

  • Patent number: 10238411
    Abstract: An elongate flexible endoscopic surgical scissor instrument includes an actuating means at the proximal end and a blade assembly that includes pair of pivotable scissor blades at the distal end. The actuating means is adapted to place the scissor blades in an opened or closed configuration. The scissors include a torque-transmitting shaft assembly that couples the proximal end of instrument to the blade assembly positioned at the distal end. Rotation of the torque transmitting shaft assembly at the proximal end causes the distally-located blade assembly to similarly rotate in both the open and closed configurations, which can provide precise targeting.

  • Patent number: 10231771
    Abstract: A catheter-based device tracks over a guidewire which has been placed from a first blood vessel into a second blood vessel. The distal tip of the catheter is advanced into the second vessel while a proximal member remains in the first vessel. Matching blunt tapered surfaces on each of the distal tip and the proximal member are clamped together, with adjacent walls of each vessel between them, after which a known, controlled pressure is applied between the two surfaces. Heat energy is then applied to the blunt surfaces for approximately 1-30 seconds to weld the walls of the two vessels together. After coaptation of the vessel walls, the heat is increased to then cut through the vessel walls to create a fistula of the desired size.
