20150335336 | SYSTEM FOR USE IN TREATMENT OF VERTEBRAL FRACTURES - Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure. | 11-26-2015 |
20150342588 | FORCE MEASURING JOINT DISTRACTION LEVER - A joint distraction lever for measuring a distraction force is disclosed. The joint distraction lever includes a lever body having a handle portion and a working portion. The lever body has a fulcrum extending from a bottom surface of the working portion of the lever body and a distal tip, wherein the distal tip is raised above a top surface of the working portion of the lever body. The joint distraction lever is configured to measure a distraction force applied at the distal tip during a distraction procedure when a torque is applied by an external force applied on the handle portion of the lever body. The joint distraction lever further includes an indicator configured to provide feedback related to the distraction force applied at the distal tip, as measured by the joint distraction lever. | 12-03-2015 |
