Catheter system and methods of using same
First Claim
1. A catheter system comprising:
- an introducer comprising a main body and a tubular introducer sheath projecting from the main body;
a catheter comprising a main body and an outer sheath projecting from the main body, the outer sheath configured to be at least partially advanced through the main body of the introducer;
a locking element configured to selectively lock the catheter to the introducer in an axial direction such that, when the introducer and the catheter are axially locked, axial movement of either of the introducer and the catheter in a proximal or a distal direction will cause the simultaneous and equal axial movement of the other of the introducer and the catheter so as to prevent the movement of either of the introducer and the catheter relative to the other of the introducer and the catheter; and
a stent or a stent graft axially supported by the catheter in a predeployment state;
wherein the locking element is configured such that, when the introducer and the catheter are axially locked, there is rotational freedom between the catheter and the introducer;
wherein the locking element is configured to axially lock the catheter to the introducer while the stent or the stent graft is released from the catheter system.

Abstract
Some embodiments are directed to a catheter system comprising an introducer having a main body, an introducer sheath projecting from the main body, and a first seal supported within the introducer and a catheter having a main body, an outer sheath projecting from the main body, a second seal supported within the catheter, and an inner core configured to be advanced axially through the main body, the second seal, and the outer sheath. The introducer can be configured to be selectively engageable with the catheter so that the catheter can be selectively and removably linked with the introducer in the axial direction. The catheter system can also be configured such that, when the introducer and the catheter are linked, the catheter can be rotatable relative to the introducer. The introducer can be configured to radially restrain an endoluminal prosthesis.
