Abstract
A multilumen catheter assembly including an elongated body defining a first lumen having a sidewall extending between its proximal end and a first lumen distal end proximate the body distal end and a first distal opening disposed proximate the first lumen distal end, and a second lumen connected to the sidewall and extending between the proximal end and a second lumen distal end proximate the body distal end, the second lumen distal end distal of the first lumen distal end. The second lumen includes a second distal opening disposed distally of the first distal opening. A self-expanding protector adjoins the elongate body distally of the first distal opening and extends from an inner edge along the elongate body outwardly and proximally to a free proximal edge that extends circumferentially about the elongate body proximate the first distal opening. The protector defins through-ways that permit blood flow past the protector.
