1. A medical device delivery system comprising:
an elongated tubular member having a distal end portion, a proximal end portion, and a lumen extending therethrough;
a joining element coupled to a distal end portion of the elongated tubular member, the joining element comprising:
a bumper having a distal end portion configured to engage a proximal portion of a medical device;
a proximal portion adjacent the distal end portion of the elongated tubular member, wherein the proximal portion defines a slot having a length along a first direction; and
an aperture extending through the bumper and the proximal portion of the joining element, the aperture having a first cross-sectional dimension along a second direction and a second cross-sectional dimension along a third direction different from the second direction, the first cross-sectional dimension being greater than the second cross-sectional dimension, wherein the first direction is about orthogonal to the second direction; and
an elongated shaft having a distal region and a flattened region proximal of the distal region, the flattened region having a greatest cross-sectional dimension that is smaller than the first cross-sectional dimension of the aperture but larger than the second cross-sectional dimension of the aperture, wherein the flattened region is at least partially received within the slot.

6. A medical device delivery system comprising:
an elongated tubular member having a distal end portion, a proximal end portion, and a lumen extending therethrough;
a joining element coupled to the distal end portion of the tubular member, the joining element comprising:
a bumper having a proximal face abutting the distal end portion of the elongated tubular member;
a proximal portion extending proximal of the proximal face and into the lumen of the elongated tubular member; and
an aperture extending through the bumper and the proximal portion of the joining element, the aperture having a first cross-sectional dimension along a first radial axis and a second cross-sectional dimension along a second radial axis, the first cross-sectional dimension being greater than the second cross-sectional dimension; and
an elongated shaft coupled to the joining element, the elongated shaft comprising:
an intermediate portion extending distal to the bumper and configured to receive a medical device thereover;
a proximal portion extending through the joining element aperture; and
an engagement feature disposed along the proximal portion of the joining element, the engagement feature having a first radially outermost dimension along a first radial direction and a second radially outermost dimension along a second radial direction, the first radially outermost dimension being smaller than both the first cross-sectional dimension and the second-cross sectional dimension of the aperture, the second radially outermost dimension being smaller than the first cross-sectional dimension of the aperture but larger than the second cross-sectional dimension of the aperture.

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.
