A medical device for capturing renal calculi includes an inflatable balloon, an elongated shaft extending through an orifiace defined by the balloon and attached thereto, a basket apparatus deployable via a distal end of the shaft, and a sheath. The basket includes two or more wire loops that capture calculi and have a collapsed configuration when the basket is positioned within the distal end of the shaft. The medical device can be used by dilating a percutaneous tract by inflating the balloon. A sheath can be advanced over the balloon to create an access route. The basket can be utilized without the removal of the balloon. The balloon can be deflated to allow the shaft and basket to be manipulated in the access route. The shaft and basket can be retracted from the access route to retrieve renal calculi.
