  • Publication number: 20240122678
    Abstract: Methods and systems are provided for generating a treatment plan for arch expansion where a polymeric shell appliance is utilized to generate one or more activation forces that facilitate tooth movement. The polymeric shell appliances may comprise one or more tooth receiving cavities, in which each of the plurality of tooth receiving cavities is shaped and arranged to provide a counter moment of each of the plurality of teeth.

  • Patent number: 10869655
    Abstract: Systems and methods for the treatment of perforator veins for venous insufficiency are described. The systems can include a catheter assembly comprising a proximal hub, a spin lock on the proximal hub, a elongate body overmolded to the proximal hub, and a distal end, the catheter, the elongate body configured to be placed within a perforator vein; an extension tubing having a proximal female hub, a distal male hub, and an elongate body therebetween, the distal male hub having a spin lock thereon, the distal male hub configured to be attached to the proximal hub of the catheter assembly; a syringe filled with a volume of media including cyanoacrylate; and an injector configured to automatically dispense a bolus of the media sufficient to coapt the perforator vein from the syringe upon actuation of a control on the injector. Methods are also disclosed.

  • Publication number: 20190343535
    Abstract: Methods and apparatus for treating veins are disclosed. In one example, a method for treating a vein includes: positioning a distal end of a delivery tool, such as a syringe and needle or catheter, within the vein; introducing media from the delivery tool into the vein; and creating an occlusion in the vein by exposing the media to energy using an artificial energy source.
