1. A device component for a prosthetic heart valve delivery system, the component comprising:

  • a tip;

    a plurality of arms moveable relative to the tip; and

    an assembly for each of the plurality of arms;

    wherein each assembly comprises an elongate member extending from a proximal end to a distal end,a fixed member coupled with a base end of the tip, and an adjustment member coupled with the distal end of the elongate member, wherein the respective arm is further movably connected to the fixed member, wherein the device component is configured such that in response to an axially applied force applied to the elongate members, the tip transitions from a first, conical profile to a second, expanded profile, wherein a radial spacing between a proximal end of the respective arm and the respective elongate member in the second, expanded profile is greater than the radial spacing in the first, conical profile;

    wherein for each of the assemblies a distance between the fixed member and a distal end of the respective arm varies in the expanded profile as compared to the conical profile.
