1. A catheter comprising:
an elongate member extending from a proximal end to a distal end, wherein the elongate member comprises a wall defining a longitudinally extending lumen;
a fixation member;
a pull wire extending axially through the wall from the proximal end of the elongate member to the fixation member, wherein the pull wire is coupled to the fixation member; and
a distal member extending from the distal end of the elongate member to a distal end of the distal member, wherein the distal member is configured to receive a leadless cardiac pacing device and deploy the leadless cardiac pacing device within a heart of a patient,
wherein the leadless cardiac pacing device comprises a pulse generator configured to deliver pacing therapy,
wherein a distal end of the fixation member is spaced proximally from the distal end of the distal member,
wherein the distal member encases at least a portion of the fixation member,
wherein the fixation member comprises an annular band defining a through-hole, and wherein a portion of the distal member extends through the through-hole to an exterior surface of the wall of the elongate member, and
wherein the elongate member is configured to deflect from an initial configuration to a deflected configuration in response to a pull force applied to the pull wire.
