Abstract: A protective system for a cast saw includes a voltage source and a processor coupled to the voltage source. The processor is configured to apply a voltage to a saw blade of a cast saw. The processor is also configured to receive a voltage reading taken across a conductive layer that is at least partially embedded in a cast. The processor is also configured to determine whether the received voltage reading exceeds a threshold voltage. Responsive to a determination that the received voltage exceeds the threshold voltage, the processor is further configured to activate an alarm to warn a user of the cast saw that the saw blade is in contact with the conductive layer.

Abstract: A bone stent facilitates bone fixation via interior contact, as may be useful for flexible entry into a sidewall of an elongated bone. As consistent with one or more embodiments, a stent includes proximal and distal end caps connected by a plurality of elongated members extending longitudinally between the end caps, and a flexible cable extending through the proximal end cap and connected to one of the end caps. The flexible cable, end caps and elongated members are responsive to the end caps being moved toward one another by laterally bending the elongated members outwardly away from one another, with the cable fixing the elongated members in the compressed state (e.g., while applying pressure to the interior sidewalls of a bone). When the end caps are released from the compressed state, the longitudinal compressive force is released and the elongated members elastically return to the uncompressed state.
