A split-tip catheter and methods for deploying a split-tip catheter in a right atrium are provided. The catheter is configured with a distal potion including a first and a second distal end regions elastically divergable from alignment along a splitting plane to regain a relaxed configuration. The first distal end region terminates in a first tip having a first forward opening, and the second distal end region terminates in a second tip having a second forward opening. Catheter deployment may include directing the first forward opening generally towards an anterior right atrium wall portion and applying the first forward opening to withdraw blood from the right atrium.
