Patent attributes
A pull wire can be retracted from a catheter by using a retraction system having an opening sized to pass through the pull wire and engage the catheter, two clamps positioned around the pull wire, a shuttle on which the clamps are mounted, and a slider having at least one contact for contacting and moving one or both clamps. To retract the pull wire, the slider can be moved proximally, the contact(s) can engage one or both clamps on the shuttle, the clamps can move so that the clamps come together and grip the pull wire, and the slider can then be moved further proximally to translate the shuttle, clamps, and pull wire proximally thereby extracting the pull wire from the catheter. The shuttle and slider can subsequently be moved distally without translating the pull wire.
