Patent number: 9623178Abstract: A deployable infection treatment system includes a cannula device comprising a cannula body having a proximal end, a flared distal end, and a lumen extending therebetween. The lumen has a longitudinal x-axis extending therethrough. A sponge or drain is provided, the sponge having a distal end and a proximal end, wherein in a non-deployed configuration, the sponge is compressed within the cannula body's lumen and in a deployed configuration the distal end of the sponge expands out of the cannula body's lumen. An integrated pump and vacuum device is provided, wherein when the sponge is in a deployed configuration, the device is in fluid communication with a therapeutic fluid source. The pump controls the delivery of the therapeutic fluid to the proximal end of the sponge. The vacuum controls the extraction of the therapeutic fluid and infectious material from the proximal end of the sponge.Type: GrantFiled: January 9, 2014Date of Patent: April 18, 2017Assignee: The Cleveland Clinic FoundationInventors: Viktor E.

Patent number: 9522069Abstract: A spinal cage with a wall extending in a longitudinal direction defining an interior space is disclosed. There is also provided a deployable element in movable relation to the spinal cage. In some embodiments, there is a rib, and the rotatable member is engaged at one end with the wall and at the other end with the rib. In some embodiments, the spinal cage is provided with holes for screws that can be directed at adjacent vertebrae for fixation. Such a spinal cage can be used with the spin-plate or with the screws. The screws and the spinal cage may have features that cooperate to prevent back-out of the screws.Type: GrantFiled: June 27, 2014Date of Patent: December 20, 2016Assignee: Theken Spine, LLCInventors: James Bruffey, Bret E. Hartzell, Andrew Paul Tojek
