Abstract: A guidance device may include a base member including a hole extending therethrough. The guidance device may include a handle coupled to the base member. Additionally, a driver may be positioned within the base member and coupled to a shaft extending between the base member and the handle.

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: The present disclosure relates generally to the field of medical devices and establishing access to a target within the body, such as placing an access needle into a renal capsule into the human body. In particular, the present disclosure relates to devices and methods for performing a percutaneous nephrolithotomy (PCNL) procedure accurately and efficiently while minimizing exposure of the medical professional to harmful radiation.

Abstract: According to a general aspect, an insertion device includes an elongate member defining a lumen, a handle member movably coupled to the elongate member, a plunger member, at least a portion of the plunger member being disposed within the lumen defined by the elongate member, and an actuation member operatively coupled to the plunger member, the plunger member being configured to move from a first position within the lumen to a second location within the lumen in response to the actuation member being actuated.

Abstract: A medical device includes a handle with a proximal arm and a distal arm. The proximal arm and the distal arm are pivotable via a joint. The medical device also includes a tube coupled to the distal arm and a drive wire. A distal portion of the drive wire includes an expandable end effector. A portion of the drive wire is positioned within the tube, and a different portion of the drive wire extends proximally of the distal arm and is coupled to the proximal arm.

Abstract: A guidance device may include a base member, a support coupled to the base member, and a guide coupled to the support. The guide may be movable relative to the base member and may include a through hole extending therethrough.

Abstract: A system for treating tissue including a clip assembly including a pair of clip arms, a proximal end of each of the clip arms slidably received within a channel of a capsule and moveable between a tissue receiving configuration and a tissue clipping configuration. The system also including an applicator releasably coupleable to the clip assembly, the applicator including a control member connectable to the proximal end of each of the clip arms and a locking sleeve coupleable to a proximal end of the capsule via a deflectable tab including an engaging structure configured to engage a corresponding engaging structure at the proximal end of the capsule and a releasing structure proximal of the engaging structure, the releasing structure engagable with a portion of the control member to deflect the deflectable member and disengage the engaging structure of the locking sleeve from the corresponding engaging structure of the capsule.
