Abstract
A medical device for capturing one or more stone fragments includes a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and a basket operable with the handle. The basket includes a plurality of wires that capture the stone fragments and has a collapsed configuration when the basket is positioned within the sheath and an expanded configuration when the basket is positioned beyond the distal end of the sheath. The medical device further includes an indicator that communicates to an operator of the medical device that the size of the stone fragments exceeds a predetermined limit and a release mechanism that releases the stone fragments from the plurality of wires when the size of the stone fragments exceeds the predetermined limit. The plurality of wires are able to reset into an operable position after releasing the stone fragments.
