1. An extraction device, comprising:
a generally tubular shaft comprising a distal end configured to be inserted into a patient and a proximal end configured to be retained exteriorly of the patient;
a basket extending from the distal end of the generally tubular shaft, the basket comprising a plurality of flexible, distally extending legs each having a lobed shape, the plurality of flexible, distally extending legs including respective distal ends that are biased generally radially outward to at least partially define a basket distal opening;
a handle disposed at the proximal end of the generally tubular shaft;
an actuator disposed on the handle; and
a closure line operatively coupled to the actuator, the closure line extending distally through the generally tubular shaft, through a closure line guide disposed on the distal end of the generally tubular shaft, and generally circumferentially about the basket distal opening, the closure line being slidably coupled to each leg near its respective leg distal end;
wherein the actuator is operative between an open position and a closed position to extend and withdraw the closure line, thereby moving the basket between an open configuration and a closed configuration, respectively.
