A device for delivering an occlusive element includes an elongate pusher member having a lumen. A locking member is disposed within the lumen of the elongate pusher member. A moveable elongate releasing member is disposed within the lumen of the elongate pusher member. A filament is secured to the distal end of the elongate releasing member. The occlusive member is locked to the elongate releasing member when the filament passes through a securing member on the occlusive member and is pinched or wedged between the looking member and the elongate releasing member. The occlusive element is in an unlocked state when the elongate releasing member is retracted proximally relative to the elongate pusher member. The filament, along with the elongate releasing member, are retracted proximally until the filament is detached or uncoupled from the securing member of the occlusive member.

Mechanically detachable vaso-occlusive device

A device for delivering an occlusive element includes an elongate pusher member having a lumen extending between distal and proximal ends. An elongate releasing member is slideably disposed within the lumen of the elongate pusher member. A retaining member is disposed on the distal end of the elongate pusher member and includes a finger portion having an aperture sized to receive the distal end of the elongate releasing member. An occlusive element such as a coil is provided and includes a securing member positioned at a proximal end thereof. The securing member is releaseably secured to the finger portion of the retaining member. The securing member is secured to the finger portion when the elongate releasing member is disposed in the aperture of the finger portion and unsecured when the elongate releasing member is retracted proximally from the aperture of the finger portion.

Mechanically datachable vaso-occlusive device

A device for delivering an occlusive element includes an elongate sheath. A distal blocking member is located at the distal end of the elongate sheath and includes an aperture therein. An elongate releasing member is disposed within a lumen of the elongate sheath. The elongate releasing member includes a proximal end and a distal end with the distal end terminating in at least one retaining member. The device includes an occlusive element such as, for example, a vaso-occlusive coil that has a securing member located at a proximal end thereof. The securing member of the occlusive element passes through the aperture of the distal blocking member and the at least one retaining member is releasably secured to the securing member.
