Method for delivering ligature loops to left atrial appendage
The patent US12029429B2 outlines a method for delivering a ligature loop to the left atrial appendage of a patient, which is a critical procedure often associated with cardiac interventions. The method involves placing a ligature loop around the left atrial appendage while it is engaged with a cinchable loop of a delivery system. The cinchable loop is then rotated from a first configuration to a second configuration, allowing for the deployment of the ligature loop onto the appendage. The claims detail various aspects of this method, including the shielding of the ligature loop by the cinchable loop during the initial configurations, the cinching process prior to rotation, and the engagement of the ligature loop with a groove in the cinchable loop.
Further claims elaborate on the structural components of the ligature assembly and delivery system, including the use of a carrier tube and a support mechanism. The method also describes the potential inclusion of a grasping mechanism to secure the left atrial appendage before placing the ligature loop. Notably, the ligature loop can remain encircled around the appendage and can be released in the second configuration. The patent also introduces a delivery control mechanism that facilitates the cinching and configuration transitions of the cinchable loop, utilizing rotary drives to manage the applied torque. Overall, the claims present a comprehensive approach to enhancing the delivery and deployment of ligature loops in cardiac procedures, potentially improving patient outcomes in left atrial appendage management.
