Abstract

The invention is entitled "Retraction Force Sensing Basket". The present invention provides a stone retrieval device comprising a sheath and a stone retrieval basket comprising a distal region having a plurality of basket wires and a proximal region having one or more core wires . The stone retrieval basket is received within the sheath and is removable from the distal opening of the sheath to open the plurality of basket wires into a basket shape. The stone retrieval device further includes: a locking mechanism that locks the position of the stone retrieval basket relative to the position of the sheath; and a basket force controller that includes a first control stage and Second control level. The first control stage includes a sensor for measuring the force on the stone retrieval basket when the locking mechanism is in the unlocked position, and the second control stage includes a sensor for measuring The calculus is removed from the basket with a force sensor on it.
