Abstract
A stent is disclosed that has an elongated body having a proximal end, a distal end, at least one open spiral channel 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.
Claims24
A stent comprising:
- an elongated body having a proximal end, a distal end, at least one open spiral channel formed on the exterior surface of said body to provide fluid communication between said proximal end and said distal end, and
- a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire, wherein the central lumen has a circular, oval or elliptical cross-section and is not in fluid communication with the open spiral channel.
A stent comprising:
- an elongated body composed of a bioabsorbable polymer and having a proximal end, a distal end, at least one open spiral channel formed on the exterior surface of said body to provide fluid communication between said proximal end and said distal end, wherein said at least one open spiral channel has a rotation rate of at least 1 twist per inch, and
- a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire, wherein the central lumen has a circular, oval or elliptical cross-section and is not in fluid communication with the open spiral channel.
A stent comprising:
- an elongated body having a proximal end, a distal end, at least one open spiral channel formed on the exterior surface of said body to provide fluid communication between said proximal end and said distal end, wherein said at least one open spiral channel has a rotation rate of between about 1.5 and 3.5 twists per inch, and
- a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire, wherein the central lumen has a circular, oval or elliptical cross-section and is not in fluid communication with the open spiral channel.
A stent comprising:
- an elongated body composed of a bioabsorbable polymer and having a proximal end, a distal end, a pair of open spiral channels formed on the exterior surface of said body to provide fluid communication between said proximal end and said distal end, wherein said spiral channels have a rotation rate of at least about 1 twist per inch, and
- a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire, wherein the central lumen has a circular, oval or elliptical cross-section and is not in fluid communication with the open spiral channels.
