Abstract: A bone graft system for providing bone graft material to a site of interest includes a multiple unit bone graft material loading device and a conduit. The multiple unit bone graft material loading device is configured to accept a plurality of pre-formed bone graft material units and includes a plurality chambers configured to accept a pre-formed bone graft unit. The conduit includes a first opening and second opening. The first opening is operably connected with the multiple unit bone graft material loading device to accept bone graft material from the multiple unit bone graft material loading device. The second opening is configured to deliver bone graft material to a site of interest.

Abstract: A novel surgical lateral retraction system is provided, including a delivery device and retractor blades. The delivery device includes a shaft having distal and proximal portions and a plurality of engaging features extending along the distal portion of the shaft. The engaging features are sized and configured to slidingly engage the retractor blades, wherein each retractor blade may be attached to the shaft independently by sliding onto one of the engaging features. The shaft may include first and second curved surfaces on either side of at least one of the engaging features, wherein the first and second curved surfaces are sized and configured to correspond to retractor curved surfaces located on either side of a central channel of a retractor blade.

Abstract: A retractor system includes a frame and first and second retractor blades. The frame includes first and second securement features. At least one of the first and second securement features is movable with respect to the frame when the at least one of the first and second securement features is mounted to the frame. The first and second retractor blades each have a distal portion and a proximal portion. The proximal portions of the first and second retractor blades are configured to be secured proximate to the first and second securement features respectively, such that the first and second retractor blades may be positioned in a first position wherein the first and second retractor blades are laterally opposed.

Abstract: A hinged retractor includes a distal portion adapted to be located inside the body of a patient during a surgical procedure and a proximal portion adapted to be closer to the surgeon during a surgical procedure. The hinged retractor includes a first side including a first blade and a second side including a second blade. The second side is joined to the first side proximate to a distal end of the hinged retractor. The hinged retractor includes a pivot proximate to the distal end. The hinged retractor is movable between a closed position and an open position, wherein a distance between a proximal portion of the first and second blades increases more than a distance between a distal portion of the first and second blades when the hinged retractor is moved from the closed position to the open position.

Abstract: A process is taught for producing a smooth, damage-free surface on a SiC wafer, suitable for subsequent epitaxial film growth or ion implantation and semiconductor device fabrication. The process uses certain oxygenated solutions in combination with a colloidal abrasive in order to remove material from the wafer surface in a controlled manner. Hydrogen peroxide with or without ozonated water, in combination with colloidal silica or alumina (or alternatively, in combination with HF to affect the oxide removal) is the preferred embodiment of the invention. The invention also provides a means to monitor the sub-surface damage depth and extent since it initially reveals this damage though the higher oxidation rate and the associated higher removal rate.
