Abstract
A retrieval basket is provided for use with a surgical device adapted to capture calculi. The retrieval basket includes wires extending from a proximal end to a distal end of the basket wherein the wires converge at the proximal and distal ends. The wires in a proximal portion of the retrieval basket incline radially at an angle away from the basket's axis along relatively straight paths. The wires in a distal portion of the retrieval basket converge radially toward the axis along relatively curvilinear paths.
