Patent ID: 10925759

Abstract:
A vascular intervention device delivery system, such as for implanting a stent, includes a thumbwheel rotatably mounted in a handle. A catheter has a proximal end attached to the handle, and a distal carrier segment for mounting a vascular intervention device thereon. A retractable sheath is movable from a first position covering the distal carrier segment to a second position retracted proximally uncovering the distal carrier segment. A pull extends between the thumbwheel and the retractable sheath. A latch is positioned in the handle and moveable from a locked position at which the latch engages the radially outward thumb surface, and an unlocked position at which the latch is out of contact with the thumbwheel. A pusher, which is partially positioned outside of the handle, is operable to move the latch from the locked position to the unlocked position. The retractable sheath moves responsive to rotation of the thumbwheel.
