Abstract: Devices and methods for removal of calculus (including for example, kidney stones) are disclosed. In an embodiment, a device for removal of kidney stones includes a substantially sealable pouch that can be inserted into the kidney for capturing a kidney stone. The pouch is also designed to permit fragmentation of the kidney stone inside the pouch, while preventing kidney stone fragments from escaping from the pouch. As a result, the likelihood of dispersing stone fragments during fragmentation of a large stone is greatly lessened.
