1. A method of positioning a prosthetic implant within a heart, the method comprising:
- advancing together a delivery catheter and an introducer catheter that is preassembled over the delivery catheter into a patient'"'"'s vascular system, the delivery catheter comprising a prosthetic valve and a distal tip that can be inserted directly into the access vessel such that the distal tip dilates the access vessel for the introducer catheter,wherein during advancement, an outer diameter of a distal end of the delivery catheter being greater than an inner diameter of a distal end of the introducer catheter, the introducer catheter comprising a hemostasis valve assembly at a proximal end of the introducer catheter;
translumenally advancing the prosthetic valve to a position proximate a native valve of the heart, the prosthetic valve being at least partially disposed within the distal end of the delivery catheter during advancement of the introducer catheter; and
deploying the prosthetic valve.
