The cannon catheter--a prospective analysis.

Clinical outcomes associated with hemodialysis catheters often depend on correct tip positioning. Improper positioning of the catheter tips can reduce blood flow and lead to long-term complications. The authors evaluated the clinical performance of the Arrow Cannon II Plus hemodialysis catheter (Teleflex Medical, Research Triangle Park, North Carolina), a catheter that was designed for tip-first (retrograde) placement to ensure accurate central positioning in the right atrium for optimal flow and minimal recirculation.
