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.

The invention provides a system and method for achieving the cosmetically beneficial effects of shrinking collagen tissue in the dermis or other areas of tissue in an effective, non-invasive manner using an array of electrodes. Systems described herein allow for improved treatment of tissue. Additional variations of the system include array of electrodes configured to minimize the energy required to produce the desired effect.

An apparatus for mixing and dispensing a multi-component compound. The device includes a tubular body with an internal chamber for mixing the multi-component compound. Disposed within and extending beyond the tubular body is a rod having a mixing disc located near a distal end. Also disposed within the tubular body is a moveable piston with a central opening through which the rod may pass.

An apparatus for delivering bone cement into a vertebra, includes a cannula, a delivery device in communication with the cannula and a pressure delivery device in communication with the delivery device. The pressure delivery device provides an actuating force that acts either directly or through a medium to cause a flowable compound to be delivered from the delivery device to the cannula and into the vertebra. The pressure delivery device causes a pressurized compound to be delivered, the pressurized compound may be liquid or gaseous CO2 or other mediums.

A probe and method for removing tissue is provided. The probe comprises an elongated member, a window laterally formed on the distal end of the member, a drive shaft rotatably disposed within the lumen of the member, and a rotatable and longitudinally slidable tissue removal element disposed on the drive shaft. The probe can be used to remove tissue along the window of the probe. In one method, target tissue along the window, e.g., bone tissue, can be removed without removing non-target tissue, e.g., nerve tissue, by rotating and longitudinally sliding the tissue removal element relative to the window.

A method of manufacturing a frame assembly includes the steps of providing an underbody assembly including a plurality of structural components that are secured together so as to be generally planar in shape; providing first and second sidebody assemblies that each include a plurality of structural components that are secured together so as to be generally planar in shape; and securing the underbody assembly to the first and second sidebody assemblies to form a frame assembly. The underbody assembly can be formed by securing first and second longitudinally extending, closed channel beams to a plurality of closed channel cross members. Each of the sidebody assemblies can be formed by securing a closed channel lower rocker rail and closed channel upper roof rail to a plurality of pillars. Each of the pillars can be formed by initially securing a first stamping to the lower rocker rail and the upper roof rail, then securing a second stamping to each of the first stampings. The underbody assembly can be secured to the first and second sidebody assemblies by magnetic pulse welding to form the frame assembly.

A method of manufacturing a node for joining a plurality of structural members together, such as in a vehicular body and frame assembly, is well suited for joining structural members that are formed from differing materials. An insert is provided having a node securing portion and a mounting portion that is adapted to have a structural member secured thereto. A node is formed about the node securing portion of the insert for joining a plurality of structural members together. The insert can be formed from a first material, while the node can be formed from a second material that is different from the first material. The insert can be provided with a node securing portion having at least one aperture or protrusion formed therein, and the node can be formed within or about the aperture or protrusion. A plurality of inserts can be provided, each having a node securing portion and a mounting portion, and the node can be formed about each of the node securing portions of the inserts. The structural members can be secured to the mounting portions of the inserts before the node is formed.
