The tubular member includes a first tubular segment and a second tubular segment. The first tubular segment and the second tubular segment are slidable relative to one another to vary a length of the tubular member. The first tubular segment includes a first connector mateable with a second connector of the second tubular segment to selectively maintain the first and second tubular segments in an extended position. The second tubular segment includes a second proximal end that is mateable with a handle. ## Claims ### Claim 1 A catheter system, comprising: an outer catheter member having a proximal end, a distal end, and a passageway extending between the proximal end and the 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 distal and proximal ends of the outer catheter member so as to extend distally out of the outer catheter member, the inner catheter being configured to support a prosthetic valve at a location distal with respect to the outer catheter member; a stop located on the inner catheter, outside of and distal to a distal-most end of the outer catheter member, wherein the stop limits axial movement of the inner catheter with respect to the outer catheter member; and a handle coupled to the proximal end of the outer catheter member, the inner catheter slidably received within the handle. ### Claim 2 (depends on 1) The catheter system of claim 1, wherein the first tubular segment has a first length from the first proximal end of the first tubular segment to a distal end of the first tubular segment, the first length being greater than a second length from a proximal end of the second tubular segment to the second distal end of the second tubular segment. ### Claim 3 (depends on 1) The catheter system of claim 1, wherein the first connector is slidably and rotatably mateable with the second connector. ### Claim 4 (depends on 1) The catheter system of claim 1, wherein the first connector includes a first sleeve affixed to the first tubular segment and the second connector includes a second sleeve affixed to the second tubular segment. ### Claim 5 (depends on 1) The catheter system of claim 1, wherein the outer catheter member has a length between the proximal end and the distal end of 3 to 5 feet in the extended position of the first and second tubular segments. ### Claim 6 (depends on 1) The catheter system of claim 1, wherein the first tubular segment and the second tubular segment are comprised of Nylon. ### Claim 7 (depends on 1) The catheter system of claim 1, wherein the first connector and the second connector are comprised of polycarbonate. ### Claim 8 (depends on 1) The catheter system of claim 1, wherein the first tubular segment and the second tubular segment each have a wall thickness of 0.010 to 0.015 inches. ### Claim 9 (depends on 1) The catheter system of claim 1, wherein the inner catheter includes a valve capsule and the stop is positioned between the valve capsule and the outer catheter member. ### Claim 10 (depends on 1) The catheter system of claim 1, wherein the inner catheter includes a valve capsule. ### Claim 11 (depends on 1) The catheter system of claim 1, wherein each of the first and second tubular segments include an indicator; wherein the indicators are axially aligned when the first and second tubular segments are in the extended position; wherein the indicators are markings on the first and second tubular segments. ### Claim 12 (depends on 1) The catheter system of claim 1, wherein each of the first and second tubular segments include an indicator; wherein the indicators are axially aligned when the first and second tubular segments are in the extended position; wherein the indicators are lines on the first and second tubular segments. ### Claim 13 (depends on 1) The catheter system of claim 1, wherein the second connector is disposed within the second distal end of the second tubular segment. ### Claim 14 (depends on 1) The catheter system of claim 1, wherein a distal end of the first tubular segment has a greater diameter than a diameter of the first proximal end of the first tubular segment. ### Claim 15 (depends on 1) The catheter system of claim 1, wherein the second connector includes first and second ends and an exterior surface, the second connector further including a channel within the exterior surface of the second connector that is open to the first end.
