Abstract
A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
Claims15
A method of making a stent, comprising:
- forming an elongated body comprising a biodegradable material, wherein the elongated body has a proximal end, a distal end and a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire;
- and
- twisting the elongated body to form at least one open spiral channels on the exterior surface of said body to provide fluid communication between said proximal end and said distal end;
- and
- shaping the stent's geometry by optimizing fluid flow rate between said proximal end and said distal end, and optimizing flexibility of the stent, by adjusting a rotation rate of the spiral channels along the stent based on the optimized fluid flow rate, and
- wherein the central lumen is not in fluid communication with the open spiral channels, and wherein said at least one open spiral channel has a rotation rate of at least 1 twist per inch.
