Claim 5:
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.
