1. A device for treating a body canal, comprising:

  • a medical device that includes;

    a proximal end-piece positioned at a proximal-most end of said medical device, a first portion of the proximal end-piece defining an opening configured to receive at least a portion of an insertion device;

    a distal end-piece positioned at a distal end of said medical device, the end-pieces being spheres; and

    an elongated body portion disposed between said proximal end-piece and said distal end-piece, said body portion comprising a plurality of interconnected loops directly connected to a second potion of the proximal end-piece and to the distal end-piece and configured to fit within said body canal, each of said loops comprising a member defining at least one opening, the member of each loop passing through at least one opening of another loop to form said plurality of interconnected loops, and wherein the elongated body portion further comprises a substantially cylindrical non-loop segment having a distal end surface and a proximal end surface, the distal end surface being directly connected to a first loop of the interconnected loops and the proximal end surface being directly connected to a second loop of said interconnected loops, wherein the non-loop segment is a single continuous structure, a diameter of at least one of the end-pieces being larger than a diameter of any component of the elongated body;

    the substantially cylindrical non-loop segment having an undulating outer surface extending from a distal end of the substantially cylindrical non-loop segment to a proximal end of the substantially cylindrical non-loop segment.
