Abstract:
1. An embolic device delivery system, comprising: a pusher having a proximal end portion and a distal end portion and a lumen; a constriction component disposed at or near the distal end portion of the pusher within the lumen of the pusher, said constriction component defining an inner channel having a first cross-sectional extent that is sized to allow at least a portion of an embolic device to be received within the channel; said constriction component having a proximal end portion and a distal end portion with said inner channel therebetween, said proximal end portion of the constriction component being movable relative to its said distal end portion; said distal end portion of the constriction component is held stationary relative to the pusher, the proximal end portion of the constriction component is movable relative to the distal end portion and to the pusher, and the distal end portion of the constriction component is connected to the distal end portion of the pusher; and whereby upon movement of the proximal end portion of the constriction component relative to its said distal end portion, the inner channel defined by the constriction component changes from the first cross-sectional extent to a second smaller cross-sectional extent wherein the constriction component secures the at least a portion of the embolic device within the inner channel.
