Abstract:
1. A multilumen catheter assembly comprising: an elongated body having a proximal end and a distal end; a first lumen extending between the proximal end and the distal end, and having a first distal opening disposed at the distal end; a second lumen and extending between the proximal end and a second distal end, proximal of the distal end, a sidewall extending between the proximal end and the distal end and separating the first and second lumens, wherein the second lumen includes a second opening extending obliquely away from the sidewall distally toward the first opening; and wherein the second distal end concludes in a tip section that is undercut along the sidewall from a first side of the elongated body to a second, opposite side thereof to form an overhanging lip, thereby facilitating prevention of occlusion of the second opening by the vessel wall.
