1. A method of making a stent, comprising the steps of:
forming a polymer tube by extrusion; and cutting the polymer tube to form the stent,
wherein the stent comprises an elongated body having a proximate end, a distal end, a central axis, and a center lumen and at least one open sinusoidally undulating channel helically and longitudinally wound around the central axis and extends from the proximal end to the distal end of the elongated body,
said undulating channel formed on the exterior surface of said body to provide fluid communication between said proximal end and said distal end,
wherein said undulating channel is not in fluid communication with the center lumen, wherein said elongated body comprises a bioabsorbable material,
wherein the at least one open sinusoidally undulating channel does not protrude into the center lumen,
and wherein the at least one open sinusoidally undulating channel is a continuous channel from the proximal end to the distal end of the elongated body.
