1. A snare for snaring an article, comprising:

  • a core cable having a proximal end portion and a circumference at a distal end portion; and

    first, second and third loops, each of the first, second and third loops having a proximal end portion and a distal end portion, and a mid-portion therebetween, and being formed by spaced apart first and second sides connected together at the distal end portion of the loop, the distal end portions being positioned forward of the proximal end portions, the first side of the first loop and the second side of the second loop being arranged with one crossing over the other at a first crossover point and being disconnected, the first side of the second loop and the second side of the third loop being arranged with one crossing over the other at a second crossover point and being disconnected, and the first side of the third loop and the second side of the first loop being arranged with one crossing over the other at a third crossover point and being disconnected, wherein the second side of the second loop is positioned inward of the first side of the first loop at the first crossover point, and wherein the second side of the third loop is positioned inward of the first side of the second loop at the second crossover point, and wherein the second side of the first loop is positioned inward of the first side of the third loop at the third crossover point, the distal end portions of the first, second and third loops being disconnected from each other, the proximal end portions of the first, second and third loops each comprising two proximal ends, each proximal end being directly coupled to and positioned around the circumference of the distal end portion of the core cable such that the two proximal ends of the first loop are separated from one another by one proximal end of the second loop and one proximal end of the third loop, the two proximal ends of the second loop are separated from one another by a proximal end of the first loop and a proximal end of the third loop, and the two proximal ends of the third loop are separated from one another by a proximal end of the first loop and a proximal end of the second loop, the first, second and third loops being movable between an open position whereat the first, second and third loops extend laterally outwardly with their distal end portions in an open position and define a space therebetween for receiving at least a portion of the article therein, and a collapsed position whereat the first, second and third loops are positioned laterally inwardly from their open position with their distal end portions in a closed position closer together than when in the open position, and the mid-portions of the first, second and third loops being disconnected from each other to permit independent movement of each as the first, second and third loops are moved between the open and closed positions, wherein the distal end portion of each of the first, second and third loops has an arcuate shape, the first, second and third loops when in the open position extend laterally outwardly and forward with the mid-portions of the first, second and third loops at an angle ranging from 90 to approximately 120 degrees relative to the distal end portion of the core cable, and the distal end portion of each of the first, second and third loops curves in the direction of the core cable.
