Patent ID: 6991625

Claim:
A multilumen catheter assembly comprising: an elongated body having a proximal end and a distal end; a first lumen having: a sidewall extending between the proximal end and the distal end; a first distal opening disposed at the distal end; and a first guide wire opening disposed proximally of the distal end and co-planar with the sidewall; and a second lumen connected to the sidewall and extending between the proximal end and a second distal end, proximal of the distal end, wherein the second lumen includes: a second opening extending obliquely away from the sidewall distally toward the first opening; and a second guide wire opening disposed proximally of the second opening and in a plane generally parallel to the sidewall, at least the second guide wire opening being elongate in a direction parallel to the axis of the second lumen so that a guide wire extending therethrough may assume only a small angle out of parallel with respect to the second lumen's axis and thereby protrude less outwardly beyond the second lumen's sidewall, thereby facilitating catheter assembly passage along the guide wire through the vessel of a patient.
