Abstract: In one embodiment, an adjustable implant system includes a bone anchor having first and second ends, a bone engagement surface adjacent the first end, and a housing extending between the first and second ends. The adjustable implant system can further include a non-invasively actuatable driving element within the housing and coupled to an adjustment component configured to couple to a flexible elongate tension member which is capable of engaging a patient's soft tissue (e.g., rotator cuff or ACL). Non-invasive actuation of the driving element can cause the adjustment component to change the amount of tension on the flexible elongate tension member and consequently on the patient's soft tissue. The adjustable implant system can include an external adjustment device configured to be placed on or adjacent the patient's skin and comprising at least one energy transferring component configured to energize/actuate the driving element inside the housing of the adjustable implant.

Abstract: A surgical retractor assembly is provided having a frame that releasably couples two retractor blades.

Abstract: An implantable bone elongation device including an inner rod defining an internal cavity housing a rotational actuator having an output shaft connected to a lead screw disposed at the end of the inner rod and in threaded engagement with a threaded inner surface of an outer rod. Rotation of the lead screw converts rotation motion into linear motion resulting in telescopic movement of the outer rod relative to the inner rod. Rotational motion is converted into linear motion by components disposed in a parallel configuration thereby minimizing the overall length of the bone elongating device while maintaining a maximum stroke length. In various embodiments, additional components, such as electronic circuit boards, electrical power supply or battery power source, may be housed within the internal cavity formed by the inner rod.

The liquid mixture can be poured out of the container through the pores in the screen on the filter device and separated from the bone graft material while the DBM containing the bone graft material remains in the container. The pores are sized smaller than DBM particles to prevent the DBM particles from separated from the bone graft material with the liquid.
