Three-Dimensional Curved Catheter for Right Atrial Appendage Traversal


Available for licensing and commercial development is a three-dimensionally configured curved catheter for safe traversal of the right atrial appendage (RAA). The device is configured to optimize one-way access of the pericardial space through the right atrium and into the RAA reducing the risk of coronary lacerations. Specifically the curved catheter is best described in three segments: a proximal segment, a transitional segment and a distal segment; the transition segment having a clockwise spiral shaped curvature. When inserted into a patient, the proximal segment is positioned within the inferior vena cava, the transition segment extends across the caval-atrial junction and curves rightward, forward, and upward such that the catheter abuts a right lateral wall of the right atrium, and the distal segment curves leftward, forward, and upward from the transition segment through the right atrium such that the catheter abuts an anterior wall of the right atrium adjacent to the RAA. The catheter is configured to guide a coaxial puncturing device to through the superior left sulcal wall of the RAA.
