PULL WIRE FOR VASCULAR INTERVENTION DEVICE DELIVERY SYSTEM

摘要

A vascular intervention device delivery system includes a catheter with a proximal end attached to a 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 is attached to the retractable sheath and extends proximally from the retractable sheath toward the handle. A majority of the length of the pull has a cross sectional shape with a concave side that faces the longitudinal axis and is opposite to a convex side that faces away from the longitudinal axis. The cross sectional shape has a width that is greater than a thickness.

1. A vascular intervention device delivery system comprising:
a handle; a catheter with a proximal end attached to the handle, and a distal carrier segment for mounting a vascular intervention device thereon, and defining a longitudinal axis; a retractable sheath movable from a first position covering the distal carrier segment to a second position retracted proximally uncovering the distal carrier segment; a pull attached to the retractable sheath and extending proximally from the retractable sheath toward the handle, and a majority of a length of the pull having a cross sectional shape with a concave side that faces the longitudinal axis and is opposite to a convex side that faces away from the longitudinal axis; and the cross sectional shape has a width that is greater than a thickness.
