Abstract
A medical assembly includes an expandable-mouth catheter and an introducer tool configured to facilitate advancement of the catheter into a delivery sheath. In some examples, a distal-most portion of the introducer tool includes a plurality of axial extensions separated by triangular-shaped slits. When the catheter is received within the introducer tool and when the introducer tool is received within a tapered portion of the delivery sheath, the axial extensions are configured to collapse radially inward to radially compress the expandable member and to enable the introducer to extend farther into the delivery sheath.
