Patent ID: 8303568

Claim:
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, the first lumen having a first distal opening disposed at the distal end, and having a first guide wire opening disposed proximal the distal end; a second lumen extending between the proximal end and a second distal end, the second distal end being proximal the distal end, the second lumen having a second distal opening disposed at the second distal end, and the second lumen having a second guide wire opening disposed proximal the second distal end; wherein at least the second guide wire opening is elongate in a direction parallel to a longitudinal axis of the second lumen so that a guide wire extending through the second lumen and the second guide wire opening may assume only a small angle out of parallel with respect to the longitudinal axis of the second lumen, the guide wire thereby protruding less outwardly beyond a sidewall of the second lumen, and thereby facilitating catheter assembly passage along the guide wire through a vessel of a patient.
