US Classification:

623 111, 606191, 606200

Abstract:

Disclosed herein are various systems and methods for delivering implantable devices, such as, for example detachable embolic coils. The systems can include an embolic coil mated to a pusher wire via a detachable link comprising first and second engaging members and an expandable member or a sleeve. The expandable member or sleeve can reduce relative movement between the engaging members to inhibit premature detachment and/or jamming of the detachable link as the embolic coil is delivered through a catheter.
