Catheter system and methods of using same
First Claim
1. A catheter system comprising:
- an introducer comprising an introducer main body and an introducer sheath projecting from the introducer main body, the introducer sheath having an introducer lumen extending therethrough;
a delivery catheter comprising a delivery catheter main body, an outer sheath projecting from the delivery catheter main body having a delivery catheter lumen therethrough, and an inner core configured to advance through the delivery catheter lumen; and
a stent having a lumen axially therethrough supported about an outside surface of a distal end portion of the inner core;
wherein;
the inner core axially supports the stent such that, in use, advancing the inner core through the delivery catheter lumen simultaneously advances the stent through the outer sheath delivery catheter lumen;
the outer sheath is configured to radially restrain the stent;
the introducer sheath is configured to axially receive at least the inner core therein;
the catheter system is configured to prevent the outer sheath of the delivery catheter from advancing into the introducer sheath when the delivery catheter has reached a fully advanced position in the introducer; and
the introducer sheath is configured to directly radially restrain the stent while the stent is positioned within the introducer sheath.

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.
