Abstract:
1. 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, in the unrestrained configuration, extends from a proximal end of the plurality of coils to a distal end of the elongate core; wherein the distal portion of the elongate core includes a coating having a plurality of colors including a first color different from that of the sleeve, wherein the elongate core includes a proximal portion that extends proximally from the proximal end of the plurality of coils to a proximal end of the elongate core, the proximal portion including a coating having a second color that is different than the first color of the coating covering the distal portion of the elongate core, wherein the second color extends proximally of a proximal end of the sleeve when the entire distal portion extends distally of a distal end of the sleeve, when the entire distal portion is disposed within the sleeve, and when the distal end of the core is positioned proximal to the distal end of the sleeve, and wherein the proximal portion has at least one loop in an unsrestrained configuration, the configured to assist in maintaining an object within the plurality of coils and is located at a distance from the proximal end of the coils that is substantially greater than a distance between adjacent turns of the coils.
