Abstract
Apparatus is disclosed for use in closing a medical device and preventing splaying of wall portions or legs of the medical device while maintaining low profile and minimal bulk of the medical device. The disclosed device is a medical device including a receiver member and a closure member. The receiver member includes an internal reverse angle thread, and the closure member includes an outer reverse angle thread, matable with the inner reverse angle thread. When the closure member is threaded into the receiver member, forces tending to splaying the wall portions or legs of the receiver member cause an interference fit between thread surfaces of the closure member and the receiver member, preventing the splay from occurring.
