1. A delivery system for delivering a cardiovascular prosthetic implant using a minimally invasive procedure, wherein the deployment system comprises:
- an introducer catheter having a proximal end and a distal end;
a delivery catheter extending through the introducer catheter, the delivery catheter having a proximal end and a distal end extending beyond the distal end of the introducer catheter; and
a hemostasis seal assembly at a proximal end of the introducer catheter;
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.

10. A delivery system for delivering a cardiovascular prosthetic implant using a minimally invasive procedure, wherein the deployment system comprises:
-
a introducer catheter having a proximal end and a distal end and a lumen extending from the proximal end to the distal end of the introducer catheter, the introducer catheter having an outer diameter defined by an outer surface of the introducer catheter and an inner diameter defining the through lumen; a delivery catheter extending through the introducer catheter, the delivery catheter comprising a tubular body having a proximal end and a distal end, the distal end including a sheath jacket and stem portion extending proximally from the sheath jacket, the sheath jacket having an outer surface that defines an outer diameter of the sheath jacket, the outer diameter of the sheath jacket being greater than the inner diameter of the introduced catheter at the distal end of the introducer catheter, the stem portion having an outer surface that defines an outer diameter of the stem portion, the outer diameter of the stem portion being smaller than the inner diameter of the introducer catheter; and a cardiovascular prosthetic implant positioned at least partially within the sheath jacket. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 22)
