Abstract: A combined drill guide and suture passer for use in assisting repair of the posterior hip capsule and short external rotators following posterior approach total hip arthroplasty. The device is a sterilizable metallic surgical instrument for repetitive use during a total hip surgical procedure. The device can be embodied as surgical guide for drilling and suturing, or can be embodied as a clamp including the surgical guide.

Abstract: A surgical osteotomy fixation device having a first brace portion with a first plurality of openings formed therethrough, and a second brace portion with a second plurality of openings formed therethrough. A bridge portion extends between the first brace portion and the second brace portion, the bridge portion including at least one hole formed therethrough. The device is fastened in place to allow fixation of a tibial tubercle fragment during osteotomies during complex primary and revision total knee surgery, as well as sports and reconstructive procedures.

Abstract: A mechanism is provided for balancing I/O among available paths connected to a device. The mechanism partitions paths so a device can use all or only a subset of available paths to a device, depending on the load of I/O for other devices that are sharing the paths. The partitioning of paths is dynamic, readjusting as I/O loads change for the devices.

Abstract: An error detection mechanism is provided for detecting sequential and distributed errors in a device I/O stream. The sensitivity of the errors is user definable. The result of the error detection is fed back into the path management software, which may use the error information to decide whether a device path should be disabled. The error detection mechanism sets a time span for a time window and counts the number of errors that occur during the time window. Each time a time window ends with at least one error, the sequential error count and the distributed error count are incremented. However, if an I/O returns without an error, the sequential error count is cleared. If the sequential error count reaches a predetermined limit, the path is disabled. After a predetermined number of time windows, if the distributed error count reaches a predetermined limit, the path is disabled.
