Abstract
A catheter includes an elongated body having a first and second wall that defines at least one lumen. The first wall includes at least one outwardly extending ridge. The at least one ridge defines a lateral opening in the first wall and extends to the distal end of the body. The ridge is dimensioned and positioned to support a body vessel such that occlusion of the first lumen is substantially prevented.
