    摘要： A method includes heating a first portion of a tubular member to a first temperature greater than a temperature of a second portion of the tubular member. The first portion of the tubular member is different from the second portion of the tubular member. The tubular member is stretched after the heating such that a length of the first portion of the tubular member is associated with a width of an anulus of an intervertebral disc. After the heating and the stretching, the tubular member is disposed within a mold cavity at least until the first portion of the tubular member has a second temperature less than the first temperature and such that an outer diameter of the tubular member in a collapsed configuration is substantially constant along a longitudinal length of the tubular member.

    摘要： An apparatus includes a projection having a sharpened end portion configured to be inserted through an annulus of an intervertebral disc to define a distracted volume in the annulus. An expandable member is coupled to the projection and defines a longitudinal axis. The expandable member is configured to be expanded from a collapsed configuration to an expanded configuration in a direction substantially perpendicular to the longitudinal axis when at least a portion of the expandable member is disposed within the distracted volume of the annulus of the intervertebral disc. When the expandable member expands, it defines an expanded volume and defines a cross-sectional perimeter while in the expanded configuration. A cannula is configured to be at least partially inserted into the expanded volume. The cannula defines a cross-sectional outer perimeter having no portion extending outside of the cross-sectional perimeter of the expandable member while in its expanded configuration.

    摘要： The present disclosure is directed to a device for excising tissue including an outer hollow member having a lumen communicating with a distal opening. The device also includes an elongate member having a longitudinal axis and a distal end, the elongate member being longitudinally movable within the outer hollow member lumen such that the distal end of the elongate member can be moved from a first configuration distal to the outer hollow member distal opening and a second configuration more proximal to the outer hollow member distal opening. Further, the device includes at least one grasping member hingedly disposed about a distal portion of the elongate member along a generally longitudinal axis, wherein movement of the elongate member from the first configuration to the second configuration can cause displacement of the at least one grasping member about the generally longitudinal axis.

    摘要： Systems and methods provide for the fixation of osteoporotic and non-osteoporotic long bones, especially Colles' fractures. A cannula having a circumferential opening is inserted into cancellous bone and directed such that the circumferential opening faces the fracture. The cannula is further adapted to receive an expandable structure, the expandable structure being inserted through the cannula until it is in registration with the circumferential opening. The expandable structure is expanded through the circumferential opening into cancellous bone and toward the fracture. The expansion of the expandable structure through the circumferential opening toward the fracture causes compression of cancellous bone and moves fractured cortical bone, thus creating a cavity proximal to the fracture. The cavity is then filled with a flowable bone filling material and the material allowed to harden.

    摘要： An elongated shaft is sized and configured to establish an access path to bone having an interior volume occupied, at least in part, by cancellous bone. The elongated shaft includes a generally closed distal end portion and a side opening spaced from the closed distal end. A first tool is sized and configured to be selectively inserted into the shaft and selectively removed from the shaft. The tool includes a region that, when the first tool is inserted into the shaft, is capable of being aligned with and advanced through the side opening to project outside the side opening and contact cancellous bone. A second tool is sized and configured, upon removal of the first tool from the shaft, to introduce into the shaft a bone filling material for discharge through the side opening into the cancellous bone contacted by the first tool.

    摘要： A filtering pan apparatus for filtering solids out of fluid being removed by a vacuum system includes a base and a duct being coupled to and extending upwardly from the base. The duct has an inlet opening and an outlet opening extending into the duct, with the inlet opening being positioned adjacent to the base. A vacuum connector is coupled to and extends away from the duct and is in fluid communication with the outlet opening. The vacuum connector has a connector opening in a distal end thereof relative to the duct which extends into the vacuum connector. A filtering screen is coupled to and extends upwardly from the base. The filtering screen covers the inlet opening and is liquid permeable.

    摘要： Disclosed herein are tools, systems, methods and surgical techniques for a disposable grasping, cutting, severing and/or biting surgical instrument having sharp cutting tips. Such instruments are lighter than their equivalent stainless steel instruments currently being used, and can be designed to employ a shearing/cutting or grasping mechanism that may be suited for specific cutting and sampling bone, cartilage and soft tissue. The surgical instrument includes a slideable upper body that may have an overmolded or removably connected cutting tip assembled onto an advancing face that translates along the handle body to produce a shearing, cutting or grasping action of tissue positioned within the jaws.
