TERMINATION ASSEMBLY FOR VASCULAR INTERVENTION DEVICE DELIVERY SYSTEM
First Claim
1. A vascular intervention device delivery system comprising:
- a handle that includes an internal surface shape that defines a cage;
a thumbwheel rotatably mounted in the handle and having a radially outward thumb surface;
a termination assembly with an external shape that matches the internal surface shape of the cage and a size that permits the termination assembly to be received in the cage in exactly one orientation, and the termination assembly being mechanically connected to the handle by being received in the cage in the exactly one orientation;
a catheter extending through the termination assembly and having a distal carrier segment for mounting a vascular intervention device thereon;
a retractable sheath movable from a first position covering the distal carrier segment, to a second position retracted proximally uncovering the distal carrier segment; and
a pull extending between the thumbwheel and the retractable sheath and through the termination assembly, and the pull moving through the termination assembly, which remains stationary with respect to the handle, responsive to rotation of the thumbwheel.

Abstract
A vascular intervention device delivery system includes a thumbwheel rotatably mounted in a handle. A termination assembly is mechanically connected to the handle. A catheter extends through the termination assembly and has a proximal end attached to the handle, and a distal carrier segment for mounting a vascular intervention device. A retractable sheath is movable from a first position covering the distal carrier segment to a second position retracted proximally to uncover the distal carrier segment. A pull extends between the thumbwheel and the retractable sheath, and through the termination assembly. A stability sheath that receives the pull and the inner catheter has a proximal end that terminates in the termination assembly.
