Claim 14:
15. A medical device delivery system comprising:
a hypotube having a proximal portion, a distal portion, and a lumen extending therethrough;
a joining element positioned at the distal portion of the hypotube, the joining element comprising:
a bumper portion having a proximal-facing surface abutting a distal end of the hypotube;
a proximal portion extending proximally from the distal portion such that the proximal portion is positioned within the lumen of the hypotube; and
an aperture extending through the bumper portion and the proximal portion of the joining element, wherein the aperture has a first cross-sectional dimension along a first radial direction and a second cross-sectional dimension along a second radial direction, the second cross-sectional dimension being smaller than the first cross-sectional dimension; wherein the proximal portion of the joining element comprises a slot having a length along a third radial direction; and

an elongated member having a proximally located attachment portion including a retention region extending through the aperture and a widened region extending laterally away from a longitudinal axis of the elongate member to a greater extent than the retention region, wherein the widened region is configured to fit through the aperture in a first orientation and to collide with the bumper portion and the proximal portion of the joining element in a second orientation.
