1. A delivery system for delivering a cardiovascular prosthetic implant using a minimally invasive procedure, wherein the delivery system comprises:
an introducer catheter having a proximal end and a distal end that is tapered, the introducer catheter including a consistent outer diameter along a proximal length, and the proximal length being greater than a length of the tapered distal end of the introducer catheter;
a tapered distal tip;
a delivery catheter extending through the introducer catheter, the delivery catheter having:
an outer tubular body having a proximal end and a distal end extending beyond the distal end of the introducer catheter, the outer tubular body defining an outer surface of the delivery catheter, the distal end of the outer tubular body comprising a sheath jacket and a stem portion extending proximally from the sheath jacket, and the sheath jacket comprising an outer marker band; and
an inner tubular body having an inner marker band;
wherein in a first configuration, the inner tubular body positions a cardiovascular prosthetic implant inside the sheath jacket with the inner marker band proximal of the outer marker band and the sheath jacket contacting the tapered distal tip;
wherein in a second configuration, the inner tubular body positions the cardiovascular prosthetic implant outside the sheath jacket with the inner marker band distal of the outer marker band and the sheath jacket spaced axially apart from the tapered distal tip;
wherein the introducer catheter includes a hemostasis seal assembly attached to the proximal end of the introducer catheter, wherein the outer tubular body of the delivery catheter extends through the hemostasis seal assembly; and
wherein an outer diameter of the distal end of the delivery catheter is greater than an inner diameter of the distal end of the introducer catheter.
