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; and
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;
wherein when the introducer and the catheter are axially locked, there is rotational freedom between the catheter and the introducer while a stent or a stent graft is released from the catheter system; and
wherein the catheter further comprises an inner core that is configured to be advanceable through the main body of the catheter and the outer sheath; and
wherein the inner core is configured to be advanceable over a guidewire.

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.

12. A catheter system comprising:
-
an introducer comprising a main body and a tubular introducer sheath projecting from the main body; and 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; wherein when the introducer and the catheter are axially locked, the catheter is freely rotatable within the introducer sheath; wherein the catheter further comprises at least one deflectable tab supported by the main body of the catheter, the at least one deflectable tab configured to selectively engage the introducer by distally advancing a distal free end of each of the at least one deflectable tab into a proximal end of the main body of the introducer; wherein the catheter further comprises an inner core that is configured to be advanceable through the main body of the catheter and the outer sheath; and wherein the inner core is configured to be advanceable over a guidewire. - View Dependent Claims (13, 14, 15, 16)

17. A catheter system comprising:
-
an introducer comprising a main body and a tubular introducer sheath projecting from the main body, the tubular introducer sheath comprising a proximal end portion extending from the main body and a distal end portion; a catheter comprising a main body and an outer sheath projecting from the main body, the outer sheath comprising a proximal end portion and a distal end portion, the outer sheath configured to be at least partially advanced through the main body of the introducer; and wherein when the introducer and the catheter are axially locked, the catheter is fully rotatable within the introducer sheath; wherein the tubular introducer sheath is configured to directly radially restrain a stent or a stent graft after the stent or the stent graft has been axially advanced past the distal end portion of the outer sheath and the proximal end portion of the tubular introducer sheath; wherein the catheter further comprises an inner core that is configured to be advanceable through the main body of the catheter and the outer sheath; and wherein the inner core is configured to be advanceable over a guidewire. - View Dependent Claims (18, 19, 20, 21)
