Extractor and method for removing stones or other foreign objects from the biliary and urinary systems or from other portions of the body. The extractor includes a self-closing basket at the distal end of a catheter, with a flexible control line for opening the basket from the proximal end of the catheter. Being self-closing, the basket closes automatically about an object captured within the basket when the control line is relaxed. The extractor can be placed in the body with the aid of a guide wire, and fluids can be injected into and removed from the body through the extractor.
