Abstract:
1. An occlusive device, comprising: an elongate pusher member having a distal end and a proximal end and a lumen extending between the distal and proximal ends; a locking member disposed in the lumen of the elongate pusher member; an elongate releasing member having a distal end and a proximal end, the distal end including a filament attached thereto, the elongate releasing member being moveable within the lumen of the elongate pusher member; and an occlusive element including a securing member positioned at a proximal end; wherein the securing member is locked to the elongate releasing member when the filament is looped through the securing member and a distal end of the filament is looped back to be pinched between the locking member and the elongate releasing member such that the filament is secured to the securing member thereby preventing axial movement of said occlusive element, and unlocked when the elongate releasing member is retracted proximally relative to the elongate pusher member such that the filament passes out of the securing member thereby releasing said occlusive element, wherein the locking member is sized to prevent the elongate releasing member from deploying out the distal end of the elongate pusher member.
