1. A stent, comprising:
a body comprising coils about a longitudinal axis of the stent and along the length of the stent between a proximal end and a distal end in a substantially helical pattern, the coils defining a lumen along the longitudinal axis through the center of the body;
a distal tube having a wall extending distally from the distal end of the body, wherein the lumen extends through the distal tube;
a first aperture extending through the wall of the distal tube into the lumen;
a proximal tube having a wall extending proximally from the proximal end of the body, wherein the lumen extends through the proximal tube;
a distal retention member extending distally from the distal tube, wherein the lumen extends through the distal retention member;
a proximal retention member having a wall extending proximally from the proximal tube to a proximal end of the proximal retention member, wherein the lumen extends through the proximal retention member to the proximal end of the proximal retention member; and
a distal suture having a first end, a second end, and a mid-portion, wherein the mid-portion extends through the first aperture, and the suture extends proximally along the body from the mid-portion to the first end and the second end proximal to the proximal tube.
