    Abstract: A device having a hub assembly and a lever coupled with the hub assembly is provided. The device includes a sheath coupled with the lever and extending from the hub assembly. The sheath has a surgical elevator with a surgical elevator edge along with a hypotube having an access hole. The device has a shaver blade assembly with an outer shaft having an outer blade and an inner blade within the outer blade. The outer shaft has a stop and an access hole near the outer and inner blades. The sheath partially surrounds the outer shaft and the lever moves between a first position and a second position. In the first position, the surgical elevator edge abuts the outer shaft stop and the outer shaft access hole aligns with the hypotube access hole. In the second position, the surgical elevator edge is spaced apart from the outer shaft stop.

    Abstract: A debrider or other medical device can include an extendable and retractable stylet to ream or unclog a working lumen, a distal portal, or the like. The device can include an elongate tubular body with a proximal and a distal portion. A working lumen can extend from a proximal working lumen portal at the proximal portion of the tubular body to a distal working lumen portal at the distal portion of the tubular body. The device can also include an auxiliary passage, interconnected to the working lumen of the tubular body at an auxiliary lumen portal located between the proximal working lumen portal and the distal working lumen portal. A spoolable or otherwise extendable and retractable stylet can include at least a portion of the stylet being extendable into the working lumen and toward the distal working lumen portal via the auxiliary lumen portal, and the stylet being retractable from the working lumen via the auxiliary lumen portal.

    Abstract: A rotatable surgical instrument, system, and method includes an outer tubular member and an inner tubular member contained, at least in part, within the outer tubular member and configured to rotate relative to the outer tubular member. A distal tip is coupled to and configured to rotate with the inner tubular member, the distal tip forming a channel around a portion of the distal tip. A bearing is rotatably positioned within the channel, wherein the channel inhibits radial and axial movement of the bearing, with respect to the distal tip, along a major axis of the outer tubular member and inner tubular member, and wherein the bearing is configured to inhibit deflection of the distal tip from the major axis.
