Patent number: 9545250Abstract: A retractor for use in spinal surgery comprises a frame including a ring member defining a generally central interior space. A plurality of blades is releasably supported respectively to slidable arms each supported on the ring member for individual translational movement relative to the ring member. The blades define an initial substantially enclosed opening that is expandable for use in a surgical procedure. A clutch mechanism supported on the ring member is associated with each arm to individually selectively engage each such arm with a rotatable main gear such that upon rotation of the main gear by a single actuator any one, all or any desired combination of arms may be translated relative to the ring member to move the blades and expand the opening in one or more selected desired directions.Type: GrantFiled: May 14, 2014Date of Patent: January 17, 2017Assignee: Spine Wave, IncInventors: Hubert W. Pfabe, Thomas R. Rainey

Patent number: 8968405Abstract: An interbody fusion device is provided that includes an interbody cage, a fixation system and an actuation mechanism to deploy one or more blades. The cage acts as an intervertebral spacer and provides resistance to the compressive loads in the spinal column. The fixation system includes an anchor and a ramp. These components could be manufactured from various medical grade materials.Type: GrantFiled: August 24, 2009Date of Patent: March 3, 2015Assignee: Incite Innovation LLCInventors: John M. Kirwan, R. Quinn Brown, Hubert W. Pfabe

Patent number: 8460388Abstract: A spinal interbody device is provided having a cage and an anchor. The cage includes a center portion with a first surface and a second surface. A first arm and a second arm extend from the center portion with the first arm having a pair of first projections and the second arm having a pair of second projections. The pair of first projections and the pair of second projections are disposed on opposing sides of an open side. The anchor includes a blade that is movable between a first position and a second position. The blade is disposed to engage the first surface and deflect as the anchor is moved from the first position to the second position. Wherein the blade is at least partially disposed between one of the pair of first projections and the center portion when the anchor is in the second position.Type: GrantFiled: October 28, 2011Date of Patent: June 11, 2013Assignee: Incite Innovation LLCInventors: John M.
