    摘要： An apparatus for delivering bone cement into a vertebra includes a cannula and a mix and delivery device pivotally coupled to the cannula. The mix and deliver provides a single device in which a flowable compound may be mixed and the dispensed into the vertebrae through the cannula. The mix and delivery device includes a piston, slidably disposed within a barrel of the device, for advancing the bone cement through an outlet communicating with the cannula. An actuating device, which exerts a pressure, is connected to an inlet on the mix and delivery device (either directly or through a tube). The pressure created by the actuating device is used to advance the piston within the mix and delivery device.

    摘要： Tissue removal probes comprise an elongated member, a drive shaft rotatably disposed within the member, and a rotatably tissue removal element mounted to the distal end of the drive shaft. One tissue removal element comprises a plurality of tissue-cutting filaments affixed at proximal and distal ends of the tissue removal element. The cutting filaments may have optional hinge points that allow the distal end of the tissue removal element to be inverted, thereby transforming the tissue removal element from a tissue-cutting device to a tissue-grasping device. Another tissue removal element may have a blunted tip to prevent distal tissue trauma and an irrigation port to provide irrigation fluid to the removed tissue and/or tissue removal element. Another tissue removal element has a proximal and distal spiral grooves that are oppositely pitched, so that removed tissue can be collected in the middle of the tissue removal element. Another tissue removal element has independent counter-rotating tissue removal elements to maintain stability during a bone cutting procedure. Still another tissue removal element takes the form of a drill bit with fluted cutting grooves. Yet another tissue removal element has cascading tissue-cutting notches that can be reciprocatably moved to remove tissue within a hole.

    摘要： A tissue removal device and method of using the device to remove tissue from a patient is provided. The tissue removal device comprises a tissue removal probe and a sheath slidable relative to the probe. The probe has a tissue removal element, and the sheath has a portion that exposes the tissue removal element. The sheath distal end may be pre-shaped to bend when slid distal to the probe. The probe may have a window through which the tissue removal element is exposed.

    摘要： Apparatus for mixing and dispensing a multi-component bone cement includes a housing forming a mixing chamber, the housing having respective proximal and distal openings in communication with the mixing chamber, at least a portion of the mixing chamber extending from the proximal opening having a substantially uniform cross-section. A mixing assembly includes a rod extending into the mixing chamber and one or more mixing elements, e.g., a perforated disc or rotating blades, attached proximate a distal end of the rod, the mixing element(s) of a type such that movement of the rod relative to the housing causes the mixing element(s) to mix bone cement located in the mixing chamber. A dispensing piston has an outer periphery sized to seal the proximal opening of the mixing chamber, while allowing the piston to be moved in a distal direction through the chamber, the piston having an opening through which the rod extends, the rod having a stop fixable at a selected location along the rod for engaging and moving the piston distally through at least a portion of the mixing chamber.

    摘要： The present invention provides a protective sheath assembly which combines the function of an introducer, the function of a protective sheath and the function of a sealing valve in an integrated assembly. The protective sheath assembly of the present invention preferably comprises a protective sheath, a strain-relief tubing, and a connecting member or a hub. These parts are mounted, removably or permanently, into an integral device. The protective sheath assembly can also be used in combination with an introducer such as a needle introducer. The protective sheath has a proximal end, a distal end, and an elongated hollow body defining a lumen along the longitudinal direction of the protective sheath. A hub is provided to secure the proximal end of the protective sheath to an introducer. The lumen of the protective sheath serves to accommodate and protect a balloon catheter, as well as seal around the catheter.
