The prosthesis is attached to three position-fill lumens (PFLs), used to position and align the prosthesis precisely, and loaded into the 18 French delivery system. The delivery system works over a 0.035” guidewire, and an atraumatic nosecone tip allows smooth transition from the guidewire to the housing sheath. Additionally, the delivery system includes an accessory recovery sheath that allows a smooth and straightforward retrieval of the DFM valve through an 18 French introducer sheath.
