Abstract
A catheter is provided that includes an elongated tubular body extending to a distal end. The tubular body has a first and a second lumen with a septum disposed therebetween. The tubular body includes a first wall that defines the first lumen and a second wall that defines the second lumen. A portion of the septum extends distally beyond the first lumen and the second lumen. The first wall includes a first wall extension that extends distally beyond the first lumen and is spaced apart from the portion of the septum. The first wall extension defines a concave surface facing the portion of the septum. Alternatively, the septum has a septum extension that extends distally beyond the first lumen and the second lumen. In alternate embodiment, the septum extension defines a first planar surface and an opposing second planar surface.
