A surgical extractor for removing objects from a body including, for example, calculi, such as kidney stones and gall stones. The extractor includes a handle at a proximal end with a slider for operation by a physician. At the distal end the extractor includes a plurality of wires with each wire comprising a first portion having an individual strand and a second portion comprising a plurality of filaments. When a retaining sheath is retracted, the wires, formed of a shape memory material such as stainless steel, expand such that each of strands assume a spaced relationship to define a first section of a basket and the plurality of the filaments assume a spaced relationship to define a second section of the basket. The use of a basket formed by wires having a first section having an individual strand and a second section having the plurality of filaments promotes capture of objects within the body by having widely spaced wires in the first section, retention of such objects in the second section by multiplying the number of contacts with entrapped object, and improved selective release of such objects without any deleterious effect on the reliability or size of the extractor. Additionally, use of the basket enables improved dislodgment and capture of embedded or impacted objects.

A rigid extractor is revealed, a rigid device for use in percutaneous procedures to remove kidney stones directly from the kidneys. The rigid extractor uses a handle fixed to an outer rigid cannula, and an inner cannula to control an extraction device that may be removable from the inner cannula. The extractor is desirably used with a fluoroscope, in which the surgeon maneuvers the extractor with the aid of a view of the operating field provided by the fluoroscope. The surgeon then maneuvers the extractor to grasp the kidney stones and remove from the patient. The extractor may also be used with a nephroscope. The device may be used with a removable extraction device such as a basket, a grasper a pair of jaws, or a pair of scissors.
