Abstract

See full text

A method of making a barbed microcatheter having fluid egress openings includes obtaining a barbed microcatheter blank having a hollow tube with a proximal end, a distal end, and an elongated lumen that extends between the proximal and distal ends of the hollow tube, and first and second flattened regions that extend along opposite sides of the hollow tube. The method includes removing material from the first and second flattened regions of the barbed microcatheter blank to form barbs projecting outwardly from the opposite sides of the hollow tube, and using cutting elements for forming fluid egress openings in a wall of the hollow tube that are in fluid communication with the elongated lumen of the hollow tube. The method includes forming a tissue anchor that is connected with the proximal end of the hollow tube, and securing a surgical needle with the distal end of the hollow tube.
