Patent number: 9358715Abstract: A mixer gun system includes a holder cap configured to separately store components in separate chambers. The components are selectively releasable through channels fluidly communicating with the separate chambers. The components are constituent materials for a bone cement mixture. A body forms a mixing chamber and is configured to receive the holder cap. The mixing chamber includes an opening corresponding with the channels for the separate chambers. A piston is disposed within the mixing chamber. A plunger is coupled to the piston and is configured to be biased toward the mixing chamber such that when the components are released into the mixing chamber a pressure developed by a biased motion of the plunger and piston infuses the components to form bone cement. Upon resetting the plunger and the piston, the bone cement is dispensed from the mixing chamber by the same biased motion. Methods of use are disclosed.Type: GrantFiled: April 13, 2012Date of Patent: June 7, 2016Assignee: KYPHON SÀRLInventor: Mark Quinto
