ABSTRACT:
A medical device can be used to entrain biological or foreign material during a medical procedure for the fragmentation of the material. The device also can be used to remove the material safely from the body. The device has a core element with a first portion extending substantially longitudinally and a second portion wound to form at least a helical coil in the shape of cone. A flat wire can substantially wrap the first and second portions of the core element, or a wire can substantially wrap the first portion and a sheath can substantially cover the second portion.
