A system for removing a kidney stone from a ureter may include: an elongate, flexible, outer shaft having a distal end configured to be advanced into the ureter and a proximal end; an elongate, flexible, inner shaft extending through at least part of the outer shaft; an expandable stone retention member extending through at least part of the inner shaft and moveable along the longitudinal axis relative to the inner shaft; an elongate, flexible camera positioned coaxially within the retention member shaft, such that a distal end of the camera is located at or near a distal end of the inner shaft; and a handle coupled with the proximal end of the outer shaft, a proximal end of the inner shaft, and a proximal end of the retention member shaft.

Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.

A catheter system that is actuatable to a deployed state and includes a catheter body and a dilator positioned at least partially within the lumen of the catheter. A distal end of the dilator can be releasably connected to a distal tip of the catheter body. The dilator can be retractable to expand and invert the distal tip and form a funnel shape in the deployed state.

The device disclosed herein is used to the remove a thrombus from the vasculature. It includes an aspiration catheter and a thrombus retrieval device that extends through the lumen of the aspiration catheter. An expandable braided assembly extends over a distal region of the retrieval device, and an activation wire extends through the lumen of the retrieval device to attach to and control the expansion of the braided assembly. Applying tension to the activation wire causes the braided assembly to expand to a diameter of the practitioner's choosing. For example, the practitioner may apply a first level of tension to the activation wire to deploy the braided assembly to a first diameter and then later change the diameter by applying a different level of tension. The expanded braided assembly contacts the thrombus and is pulled proximally toward the aspiration catheter to assist in thrombus removal.

A medical device is operable to extend and/or retract elements suitable for a particular purpose. The elements are extended and/or retracted in response to a stress applied by way of stretching and/or retracting the device, among other methods. The elements may remain extended and/or retracted or may recoil back to an initial position upon the removal of the force. In various embodiments, the elements are used to treat or deliver treatment to a target site within a body.
