20120271313 | LONG SCRAPER TOOL FOR DISCECTOMY - A scraping instrument is disclosed that includes a handle assembly having a trigger. The scraping instrument also includes an elongate shaft having an inner lumen extending therethrough along a longitudinal axis between proximal and distal ends thereof. The proximal end of the elongate shaft is connected with the handle assembly. A control rod extends through the inner lumen of the elongate shaft hand has a first end connected with the trigger and a second end extending outside the distal end of the elongate shaft. The second end of the control rod includes a connection pin. A yoke is connected with the distal end of the elongate shaft. A curette having a scraping member and a connection member is pivotally connected with the yoke. Upon compression of the trigger the control rod is forced to move along the longitudinal axis thereby causing the curette to rotate along a latitudinal axis. | 10-25-2012 |
20120271357 | TOOLS AND METHODS FOR THE PREPARATION OF THE FACET JOINT - Methods of fusing a facet joint that include inserting a cannula with a first end of the cannula at the facet joint and a second end positioned away from the facet joint. One or more tools may be inserted through the cannula to contact against and treat one or both vertebral members to enlarge the facet joint. An osteogenic material is then inserted into the enlarged facet joint to facilitate fusion of the first and second vertebral members. | 10-25-2012 |
20120277811 | BONE TAMP AND METHODS OF USE - A system comprises an inflatable bone tamp including a plurality of linearly aligned expandable bodies. The system further comprises an elongated tubular shaft extending through the plurality of linearly aligned expandable bodies. The elongated tubular shaft includes a shaft wall and an interior partition structure. The system further comprises a plurality of channels extending through the shaft, each of the channels formed by a segment of the shaft wall and the interior partition structure and each of the channels in communication with the respective one of the plurality of expandable bodies via openings in the shaft.

20140194885 | CATHETER WITH INTEGRATED CEMENT DELIVERY BALLOON - A bone filling device includes a catheter that defines a longitudinal axis and extends between a proximal end and a distal end. A first lumen extends along the longitudinal axis of the catheter and defines a first passageway. A second lumen extends along the longitudinal axis of the catheter and defines a second passageway. An inflatable body includes a wall that defines a fillable cavity. The fillable cavity is in fluid communication with the first passageway. A bone filler delivery port continuous with the second passageway and configured to dispense bone filling material. | 07-10-2014 |
20140269147 | BONE CEMENT MIXING AND DELIVERY SYSTEM WITH REDUCED FUME EXPOSURE - A device for mixing and containing fumes for a bone cement component including a base. The base includes an inner wall defines a chamber having a first sealable opening and a passageway. A handle extends between a proximal end and a distal end and includes a seal at the distal end. A plunger housing is configured for moveable disposal of the handle and includes a second sealable opening. The plunger housing is configured to contain a vial therein. The plunger housing is configured for engagement with the base. The plunger housing is configured to move within the passageway. A collapsible paddle attached to the handle between the proximal and distal end and configured to mix the bone cement. | 09-18-2014 |
20140276802 | ROTATABLE CUTTING INSTRUMENT AND METHOD - A surgical instrument includes a first member having an inner surface defining a first passageway. A second member is disposable within the first passageway and movable relative to the first member. The second member defines a longitudinal axis and extends between a first end and a second end configured to engage tissue. The second end includes a first surface configured for a non-penetrating engagement with the tissue and a second surface including at least two spaced apart cutting members extending axially from the first surface. The cutting members are rotatable to excise a portion of the tissue. Systems and methods are disclosed. | 09-18-2014 |
20140277030 | ULTRASONIC CUTTING DEVICE - An ultrasonic surgical device for performing a surgical procedure includes an elongated member having a proximal end and a distal end spaced along a longitudinal axis. The elongated member has an inner surface and an outer surface. The inner surface defines a passageway. A septum is configured to separate the passageway into a first conduit and a second conduit. A distal end of the second conduit terminates before a distal end of the first conduit to form a stepped configuration. An ultrasonic-driven cutting blade is disposed within the second conduit and is configured for cutting tissue such that the cutting blade vibrates ultrasonically to cut tissue. The distal end of the first conduit includes an outlet configured for delivering material to a surgical site and the distal end of the second conduit includes an inlet configured for aspirating the surgical site. | 09-18-2014 |
