Abstract
Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.
Claims19
An implantable medical device for use along the biliary and/or pancreatic tract, the implantable medical device comprising:
- a tubular member having a first end and a second end opposite the first end;
- wherein the tubular member has an outer surface and an inner surface, the inner surface defining a lumen extending through the tubular member from the first end to the second end;
- wherein the tubular member is formed of one or more wire filaments that are woven together;
- wherein the tubular member includes a longitudinal channel formed in the outer surface by displacing the one or more wire filaments radially inward;
- wherein the tubular member includes a longitudinal ridge formed in the inner surface by the displacement of the one or more wire filaments radially inward to form the longitudinal channel;
- wherein the tubular member includes a cylindrical region and a flared region adjacent to the cylindrical region, wherein the cylindrical region extends to the second end of the tubular member and the flared region extends to the first end of the tubular member, wherein the longitudinal channel only extends along the cylindrical region of the tubular member such that the flared region is devoid of the longitudinal channel;
- and
- a covering disposed about the tubular member.
An implantable medical device, the implantable medical device comprising:
- a braided stent having a first end and a second end, the braided stent having a length measured from the first end to the second end;
- wherein the braided stent has an outer surface with a longitudinal channel formed therein, the longitudinal channel being configured to drain fluid therealong, the longitudinal channel extending along a majority of the length of the braided stent;
- wherein the braided stent includes a cylindrical region and a flared region adjacent to the cylindrical region, wherein the cylindrical region extends to the second end of the braided stent and the flared region extends to the first end of the braided stent, wherein the longitudinal channel only extends along the cylindrical region of the braided stent such that the flared region is devoid of the longitudinal channel;
- and
- a covering disposed about the outer surface of the braided stent.
An implantable medical device, the implantable medical device comprising:
- a braided stent formed of a plurality of interwoven wire filaments, the braided stent having a first end, a second opposite the first end, an outer surface and an inner surface, the inner surface defining a lumen extending therethrough along a central longitudinal axis of the braided stent, the braided stent having a length measured from the first end to the second end;
- wherein the braided stent includes a longitudinal channel extending parallel to the central longitudinal axis formed along the outer surface by displacing the plurality of wire filaments radially inward, the longitudinal channel being configured to drain fluid therealong, the longitudinal channel extending along a majority of the length of the braided stent;
- wherein the braided stent includes a longitudinal ridge formed in the inner surface by the displacement of the plurality of wire filaments radially inward to form the longitudinal channel;
- wherein the braided stent includes a cylindrical region and a flared region adjacent to the cylindrical region, wherein the cylindrical region extends to the second end of the braided stent and the flared region extends to the first end of the braided stent, wherein the longitudinal channel only extends along the cylindrical region of the braided stent such that the flared region is devoid of the longitudinal channel;
- and
- a covering disposed about the outer surface of the braided stent.
