Claim 13:
14. A vascular closure device assembly, comprising:
a sheath comprising:
a sheath main body defining a channel therethrough,
a sheath engagement portion, and
a sheath mounting portion located at a proximal end of the sheath main body, wherein the sheath mounting portion is cylindrical and has a diameter that is larger than a diameter of the sheath main body;

a housing including a mounting structure defined within the housing, wherein the sheath mounting portion is disposed within the mounting structure and is secured within the housing such that the sheath is rotatable relative to the housing, and such that the housing inhibits axial displacement of the sheath relative to the housing; and
a dilator comprising:
a dilator main body, and
a dilator engagement portion extending from the dilator main body towards the sheath,

wherein the dilator engagement portion is configured to engage the sheath engagement portion such that axial displacement of the dilator relative to the sheath causes the sheath to rotate relative to the housing;
wherein the housing is configured to inhibit axial displacement of the sheath during rotation;
wherein the mounting structure includes a cylindrical wall extending away from a proximal wall of the housing that is proximate to the dilator towards the sheath and a ledge extending radially inwards from a distal rim of the cylindrical wall; and
wherein the sheath mounting portion has an axial length corresponding to an axial length of the cylindrical wall such that the sheath mounting portion is secured between a distal surface of the proximal wall of the housing and a proximal surface of the ledge so as to inhibit axial displacement while allowing rotation of the sheath relative to the housing.
