Abstract: Hydro excavation apparatus for excavating earthen material are disclosed. The hydro excavation apparatus includes a first reservoir for holding a base fluid therein, a second reservoir for holding an additive therein, a vacuum system for removing earthen material from an excavation site, and an additive dosing assembly. The additive dosing assembly includes at least one of a pump and a valve fluidly connected to the second reservoir. The additive dosing assembly is selectively controllable to introduce an additive into at least one of the base fluid and the removed earthen material.

Abstract: Provided herein are methods of enriching a retinal pigment epithelium (RPE) cell population derived from stem cells. Such a method may comprise removing contaminating cells through the depletion of CD24 positive cells, CD56 positive cells, and/or CD90 positive cells from a starting population of RPE cells.

Abstract: Provided herein are methods of producing a photoreceptor precursor (PRP) cell population derived from stem cells. Further provided herein are methods of using the PRP cell populations, such as for therapeutics.

Abstract: Systems and methods for processing earthen slurries such as slurries of earth cuttings and, in particular, systems and methods that involve two separation units for dewatering the slurry or that involve additive mixing units are disclosed. The systems and methods may include a conveyor such as a drag-slat conveyor that removes slurry from a holding tank at which the material is dumped and toward the separation units to allow the material to be continuously processed and dumped into the holding tank.

Abstract: Transfer systems for receiving and conveying material such as earthen slurries discharged from vacuum excavators are disclosed. The transfer system may include a holding tank and a conveyor such as a drag-slat conveyor that extends into the tank to remove and convey material from the tank. The transfer system includes a hatch. The hatch is moveable from a closed position in which vehicles travel over the hatch to an open position in which the holding tank is open to receive material from the vacuum excavator.

Abstract: The instruments and methods of the present disclosure include an outer shaft, an inner shaft, a roller, and an actuator. In some examples, the outer shaft includes a lumen extending from a proximal end to a distal end. The inner shaft is disposed within the lumen. The roller rotatably is coupled with the distal end at an axis and configured to engage the fixation rod. The actuator operably couples with the inner shaft to translate the inner shaft within the lumen and cause rotation of the roller to impart linear movement on the fixation rod.

Abstract: A transverse link with a pair of opposing engagement members having a spherical ball bearing configured to fix a respective screw extender with respect to each other is provided.

Abstract: An instrument for breaking off and retaining the tab of a reduction screw is provided. The instrument includes a breaking arm and a retaining mechanism. The breaking arm is configured to break off an excess portion of the tab of the reduction screw about a weakened section. The retaining mechanism is configured to retain the broken off tab and preventing the tab from falling into a surgical site. The retaining mechanism is further configured to allow the instrument to engage another tab while simultaneously holding a predetermined number of previously broken off tabs. Accordingly, the instrument reduces surgical time as the surgeon may simply move from one reduction screw to another while breaking off the tabs until the instrument can no longer retain additional broken off tabs.

Abstract: A method for reducing a fixation rod is provided. The method minimizes the surgical corridor by performing fixation within the surgical corridor defined by the screw extender. The screw extender is attached to the spinal implant. The method includes the steps of coupling the proximal end of a first cannulated body with the screw extender and rotating a second cannulated body within the first cannulated body. The method proceeds to the step of actuating a rod pusher with a first driving feature so as to engage the rod pusher with the fixation rod. The rod pusher includes a bore. The method proceeds to the step of rotating an inserter shaft within first cannulated body, second cannulated body and bore of the rod pusher, the inserter shaft including a proximal end with a second driving feature and a distal end with a setscrew attachment feature.
