Abstract: 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.

Abstract: An embolic implantation system configured to deliver an embolic implant intravascularly to a treatment site includes an elongated delivery tube to which the embolic implant is detachably attached by a flexible loop extending through a retaining ring or opening on the embolic implant and an elongated detachment member or pull wire extending through the delivery tube and flexible loop. The pull wire has a bump near its distal end that inhibits the pull wire from moving further distally when the bump presses distally against the flexible loop and/or retaining ring. The flexible loop and retaining ring thereby serve as a distal obstruction obstructing distal movement of the bump and thereby distal movement of the pull wire into the implant.
