Abstract
A telescoping catheter including an elongated tubular member having a proximal end, a distal end, and a passageway extending between the proximal end and the distal end. 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.
Claims15
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.
