1. A medical device comprising:
- a core element including a first portion extending substantially longitudinally and a second portion including at least one loop and a helical coil tapering from a larger diameter at a proximal end thereof to a smaller diameter at a distal end thereof, wherein the at least one loop is located at a distance from the proximal end of the helical coil that is substantially greater than a distance between wound sections of the helical coil.

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.

21. 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; wherein the distal portion of the elongate core includes a coating having a color different from that of the sleeve; and wherein the coating comprises at least one colored stripe having a color different from that of a remaining portion of the coating. - View Dependent Claims (22, 23, 25, 26, 27, 28, 29, 30, 31)
