Abstract: A percutaneous nephrolithotomy (PCNL) needle may include a cannula including a shaft and a cannula hub coupled to a proximal end of the cannula shaft. A depth guide may be disposed on an outer surface of the cannula shaft. A stylet may be disposable within the cannula lumen and may include a tapered point at a distal end of the stylet and a stylet hub coupled to a proximal end of the stylet that is configured to be releasably securable to the cannula hub. An adjustable depth stop may be releasably securable to the cannula shaft at a desired position relative to the depth guide, the adjustable depth guide capable of being manipulated between an adjustment configuration in which the adjustable depth guide is moveable relative to the cannula shaft and a secured configuration in which the adjustable depth guide is secured relative to the cannula shaft.

Abstract: A training device for medical procedures may include: a back, a front, a top, a bottom, a left side, and a right side; a track including a main track portion and a plurality of diverting track portions extending from the main track portion, wherein the main track portion extends from a back end proximate the back to a forward end proximate the front; and a stricture device configured to adjust a width of the main track portion along a portion of the main track portion.

Abstract: A trainer for medical procedures may include outer walls arranged to define an interior space; and inner walls arranged within the interior space to separate the interior space into a plurality of chambers; wherein at least some of the inner walls include at least one opening connecting adjacent chambers of the plurality of chambers.

Abstract: A guidewire including an elongate inner member having a proximal portion and a distal portion, an elongate outer member disposed about the elongate inner member, wherein one of the elongate inner member and the elongate outer member is more flexible relative to the other of the elongate inner member or the elongate outer member, and the elongate inner member is movable relative to the elongate outer member.

Abstract: Medical devices and methods for using medical devices are disclosed. An access device for accessing a target site comprises a tubular member having a proximal portion and a distal portion. The access device may also include a balloon coupled to the tubular member, the balloon extending between the tubular member proximal portion and the tubular member distal portion. The access device may also include a stylet moveable with respect to the tubular member, wherein the stylet is configured to pierce through the skin of a patient.
