Tail Piece for Remote Delivery Device ( CIP of Application 15/932.942 filed 05/24/2018)

摘要

A remote delivery device is disclosed which has a tubular body and a tubular tail piece. The tubular body is crimped onto said tail piece at a desired axial position with a rearmost edge of the body abutting the protrusions at only contact segments of the rear-most edge. With the provision of spaced-apart protrusion on the tail piece, axial expansion of said tubular body caused by a crimping operation imparts less stress and axial force on the tail piece as compared to stress and force which would be imposed upon a tail piece which has a singular annular abutment extending around an entire circumference of said tail piece. This results in reducing a rate of failure of said tail piece breaking off from said body when the remote delivery device is subjected to outside stresses or forces and allows for the use of a wider range of acceptable crimp lengths.
