Abstract: A device and method for treating bone fractures/lesions using an inflatable body is provided. The inflatable body includes a balloon having a substantially flat horizontal surface for quick easy insertion into bone beneath the fracture so as to align misaligned fragments of the fracture and/or to collapsed bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and/or to restore the original position of the outer cortical bone, if fractured or collapsed. The inflatable body has a stylet attached to it's distal end so that once the inflatable body is deflated it can be twisted about the stylet to have a smaller profile so as to be easily withdrawn from the bone.

Abstract: Devices, and methods of use thereof, are disclosed for preventing tumor seeding when withdrawing the device along an entry-exit path. Some embodiments of the present invention comprise a method of withdrawing a probe through a tissue via a path that traverses at least some bone tissue, the method including withdrawing the probe through the path, and at least partially concurrently delivering energy in a bipolar manner from the probe to heat a layer of tissue surrounding the probe to a temperature sufficient for thermal coagulation necrosis of cells. The device may be withdrawn incrementally.

Abstract: A surgical instrument includes a first member including a groove. A second member includes an aperture and teeth configured to slidably engage the groove. A third member is positioned in the aperture and includes a passageway defining a first longitudinal axis and a flange. A fourth member is positioned in the passageway and includes a lip that engages the flange. The lip extends at an acute angle relative to a second longitudinal axis defined by the fourth member. A fifth member is rotatably disposed in the passageway and includes a first end surface that engages a second end surface of the fourth member defined by the lip. In a first configuration, the fourth member extends perpendicular to the first longitudinal axis. In a second configuration, the fourth member extends at an acute angle relative to the first longitudinal axis. Systems and methods are disclosed.

Abstract: 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.

Abstract: A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.
