1. A strain relief member for a medical device delivery system, comprising:
a support comprising a first end comprising a first outer diameter, a second end comprising a second outer diameter, an inner surface facing a support lumen that extends axially through the support along a longitudinal axis, and an outer surface opposite to the inner surface;
an overlay coupled to a portion of the outer surface of the support,
wherein the overlay comprises a first material and the support comprises a second material, and the first material is more flexible than the second material;
a liner disposed in a portion of the support lumen; and
a first connector disposed over a portion of the support;
wherein the liner comprises a first polymer comprising a first rigidity, the support comprises a second polymer with a second rigidity greater than the first rigidity, and the overlay comprises a third polymer with a third rigidity greater than the second rigidity.
