Abstract: A suturing instrument having a dock at the end for receiving and securing a needle attached to a suture. The suturing instrument includes a cannulated handle attached to the proximal end of a cannulated shaft. The proximal end of a needle is removably received and securely received in the curved needle dock formed on the distal end of the shaft. The suture attached to the needle passes through the shaft and out the proximal end of the handle. Once the instrument is inserted into the body (usually through a cannula), the suture is retracted at the proximal end of the instrument handle, which draws the attached needle into the needle dock. The suture dock preferably has a compound curvature which prevents substantial rotation of the needle upon insertion.

Abstract: A pattern detection circuit detects a pattern in a received bit stream, for example a repetitive 8-bit silence pattern in a stream of digital audio data. Summing circuitry forms during first alternate time periods a sum of a first sequence comprising a predetermined number of alternate bits in the bit stream; and forms during second alternate time periods an inverse of a sum of a second sequence comprising the predetermined number of alternate bits in the bit stream. It is then determined whether successive sums formed by the summing circuitry are equal.

Abstract: Embodiments described herein are related to fillers that are placed within an extraction site in need of bone augmentation and preservation. The fillers encourage sufficient new bone growth in order that normal jaw bone deterioration following tooth removal is prevented. The fillers create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone. Further embodiments described herein are related to dental implants that are arranged to provide a scaffold upon which a damaged or missing dental papilla may regrow. The dental implants may include a micro-pattern to facilitate directional cell growth.

Abstract: A retracting two-piece cannula for distracting soft tissue from bone (e.g., the articular surface of a knee) to provide a surgical workspace for osteochondral repair. After inserting an outer cannula provided with a threaded outer surface into an incision (preferably widened by one or more dilators), the outer cannula is rotated to engage the threaded outer surface with the soft tissue to be distracted. An inner cannula is then inserted into the outer cannula and advanced until it contacts the articular surface. Further relative movement between the inner and outer cannulas causes the outer cannula to be drawn away from the articular surface, thereby retracting the soft tissue and establishing the workspace. The inner and outer cannula are then locked together to maintain the workspace, and an osteochondral core may be introduced through the inner cannula.

The second programmable logic, which includes deflection shaping circuitry to align, center or steer the beams from the projection systems, utilizes data received from the first programmable logic to compensate for geometric alignment error.
