Pullwire crown and crown sleeve for catheter assembly

A method of manufacturing an intraluminal device, comprising:

• providing a flexible elongate member including a distal portion and a proximal portion;
• coupling a crown element to the distal portion, wherein the crown element includes an annular ring, a first post, and a second post, and the first post and the second post extend perpendicularly from the annular ring;
• anchoring a first pullwire to the annular ring at the first post;
• extending the first pullwire along the flexible elongate member from the crown element to the proximal portion of the flexible elongate member such that translation of the first pullwire in a proximal direction deflects the distal portion in a first direction and a second direction;
• anchoring a second pullwire to the annular ring at the second post;
• and
• extending the second pullwire along the flexible elongate member from the crown element to the proximal portion of the flexible elongate member such translation of the second pullwire in a proximal direction deflects the distal portion in a third direction and a fourth direction,
• wherein the first post and the second post are components of the crown element that are distinct from the first pullwire and the second pullwire.
