Patent ID: 11701227

Abstract:
A gimbal handle assembly including: an inner gimbal and an outer gimbal that are concentrically linked and have pivot axes that are orthogonal relative to each other, a spool coupled to and rotatable around the outer gimbal, and a plurality of draw lines attached to the spool in a circumferential configuration, wherein rotation of the spool and/or rotation of the spool and the outer and inner gimbals increases or reduces tension in the draw lines. Also disclosed are a transcatheter valve delivery assembly that includes the gimbal handle assembly, a multi-lumen catheter, a sleeve attached to a distal end of the multi-lumen catheter, and a transcatheter heart valve including an expandable valve frame. Methods of delivering the transcatheter valve to a subject are described, wherein pitch and yaw orientations of the transcatheter valve can be precisely controlled with enhanced degrees of freedom.
