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.

A medical device comprising:
- an elongate sleeve defining a lumen extending longitudinally within at least a portion of the elongate sleeve;
- an elongate core slidably disposable within the lumen, the core having a distal portion capable of transforming between an unrestrained configuration forming a plurality of coils disposed in a conical shape and a restrained configuration forming a substantially linear shape;
- and
- wherein the distal portion of the elongate core includes a coating having a color different from that of the sleeve.
A medical device comprising:
- an elongate sleeve defining a lumen extending longitudinally within at least a portion of the elongate sleeve;
- and
- an elongate core formed at least in part of nickel-titanium alloy and slidably disposable within the lumen, the core having a distal portion capable of transforming between an unrestrained configuration forming between 5 and 15 coils disposed in a conical shape and a restrained configuration forming a substantially linear shape;
- wherein adjacent turns of the coil are separated by a space less than 2 mm, and wherein the distal portion of the core includes a coating having a color different from that of a portion of the sleeve.
