First Claim
1. An interference locking joint for releasably holding a vaso-occlusive member comprising:
- (a) a holding member comprising a tubular wall section defining an opening through said tubular wall section, said tubular wall section having a longitudinal axis, and defining an interior space,(b) a mating member fixedly attached to the vaso-occlusive member, said mating member further configured to at least partially enter said opening in cooperation with an interference wire, and upon entering said opening, prevent axial movement with relation to said holding member, said mating member being axially moveable within said holding member when said mating member is not cooperating with said interference wire and(c) said interference wire, axially moveable within said holding member and having a diameter suitable for causing said mating member to at least partially enter said holding member opening.

Abstract
This is an assembly for controllably delivering vaso-occlusive devices to a selected site within the vasculature or other lumen of the human body by the use of a catheter. In particular, the device includes a holding member which is at least generally tubular and has an opening through the tubular wall. The vaso-occlusive device to be delivered has on one end a mating member which may be at least partially pressed into the opening in the wall of the holding member. The mating member attached to the vaso-occlusive member is held in the opening with an interference wire. The interference wire is axially movable within the holding member and has a diameter sufficient to hold the mating member within the wall opening. Upon proximal movement of the interference wire, the mating member becomes free to leave the holding member. The interference wire may be tapered or not. The vaso-occlusive member may be a helically wound coil or a braid or other appropriate form.
