1. A catheter system, comprising:
a prosthetic valve;
an outer catheter member having an outer catheter member proximal end, an outer catheter member distal end, and a passageway extending between the outer catheter member proximal end and the outer catheter member distal end, the outer catheter member comprising a first tubular segment telescopingly received within a second tubular segment, the first tubular segment having a first proximal end, the outer catheter member further including a first connector disposed around an exterior surface of the first proximal end, and the second tubular segment having a second distal end, the outer catheter member including a second connector at the second distal end, wherein the first connector is mateable with and positioned within the second connector to maintain the first and second tubular segments in an extended position;
an inner catheter slidably received within the outer catheter member and passed through the outer catheter member distal end and the outer catheter member proximal end so as to extend distally out of the outer catheter member, the inner catheter being configured to support the prosthetic valve at a location distal with respect to the outer catheter member;
a capsule coupled to a distal end portion of the inner catheter, wherein the prosthetic valve is contained within the capsule, wherein a proximal end of the capsule is distally spaced from the outer catheter member distal end with the outer catheter member in the extended position; and
a handle coupled to the outer catheter member proximal end, the inner catheter slidably received within the handle.
