A method is performed for permanently attaching framing structural members to an underbody of an automotive vehicle. An underbody structural member including one or more cross members and a plurality of metallic structural members are provided at a workstation. The underbody structural member is aligned to the plurality of metallic structural members at the workstation. The assembled underbody structural member and the plurality of metallic structural members are permanently and simultaneously secured at the workstation using magnet pulse welding.

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.

An implant assembly comprises an elongated pusher member, and an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member. The implant assembly further comprises an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, and a return electrode carried by the distal end of the pusher member (e.g., a coil disposed about the pusher member) in proximity to, but electrically isolated from, the severable joint. The implant assembly further comprises a terminal carried by the proximal end of the pusher member in electrical communication with the severable joint.

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.

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.
摘要:
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.
摘要:
A magnetic force system uses a magnetic implant sized and configured to be inserted in the pharynx and another magnetic implant sized and configured to be inserted in the tongue, palate, or pharynx. The system establishes different regions of magnetic interaction between the two implants across the airway, attracting and repelling, such that attractive interaction in one region of the implants combines with repelling interaction in another region of the implants, to provide a “hinge” structure. Alternatively, a magnetic force system that uses three magnetic implants sized and configured to be inserted in the tongue, pharynx, and palate, respectively. The tongue implant is attracted to the palatal implant, and repels the pharyngeal implant, forming a modified “hinge” structure. Forces of magnetic attracting bring tissue together to form a magnetic hinge joint, providing an anchor to stabilize the regions where repelling forces work to separate tissue to keep the airway open.
摘要:
A carrier is sized and configured for placement in or on a tissue region. The carrier includes at least one interior compartment. At least one ferromagnetic material is carried within the compartment. The compartment and the ferromagnetic material are mutually sized and configured to allow movement of the ferromagnetic material within the compartment in response to magnetic interaction with a magnetic material located outside the carrier. The magnetic interaction can include either a magnetic attracting force or a magnetic repelling force. The carrier can be used in association with a source of magnetism sized and configured for placement in or on a tissue region outside the carrier for magnetic interaction with the ferromagnetic material carried within the compartment, e.g., to stabilize the orientation of a tissue region within an airway.

Systems and methods are provided for resisting posterior movement of the tongue during sleep, thereby keeping an airway open. The systems and methods employ a first structure that can be placed either in or on a tongue within an oral cavity and/or in a region of hyoid muscle. The first structure includes a ferromagnetic material. The systems and methods employ a second structure that can be placed either in or on external tissue outside the oral cavity and/or in or on external tissue outside the oral cavity in a desired relationship with the first structure. The second structure includes a magnetic material that magnetically interacts with the ferromagnetic material by attracting the ferromagnetic material, thereby resisting posterior movement of the tongue.
