Bi-directional steerable catheter for accessing left atrium
The patent US12036371B2 outlines a method for accessing a target site in the left atrium of a patient using a specialized steerable catheter. The catheter features a tube with a proximal end, a distal end, and a lumen connecting the two. It includes a first segment near the distal end and a second segment extending proximally. The design incorporates two pull wires, each with wound segments that are arranged to minimize whipping during rotation. The handle of the catheter allows for selective tensioning of either pull wire, enabling bidirectional steering of the deflectable segment. The method involves inserting the catheter through the inferior vena cava and right atrium, navigating through the atrial septum until the first segment is positioned near the target site in the left atrium.
Additionally, the claims detail various configurations of the pull wires, including options for winding directions and the arrangement of straight proximal and distal segments. The catheter can be designed with the pull wires wound in the same direction or counter-wound, and the wound segments can be dispersed around the catheter's circumference. The method also allows for the rotation of the tube about its longitudinal axis while positioned within the left atrium, enhancing maneuverability. Overall, the patent presents a comprehensive approach to catheter design and operation for effective access to the left atrium in medical procedures.
