Abstract: An embolic implant includes a detachment feature configured to engage and be released from a delivery member's engagement system. The engagement system can include a loop wire extending through an opening of the detachment feature a pull wire extending through the loop wire to secure the detachment feature to a delivery tube of the delivery member. The detachment feature can include a distal extension configured to engage a distal end of the pull wire to inhibit the pull wire from moving distally into the implant. The detachment feature can also include a sleeve to align the pull wire to the distal extension and/or provide a friction force against the pull wire to inhibit longitudinal movement of the distal end of the pull wire.

Abstract: A delivery and detachment system for an implantable intravascular treatment device including a proximal inner tube telescopically receivable and axially slidable in a proximal direction within the lumen of the outer delivery tube. Specifically, the proximal inner tube comprises a proximal section and a distal section having different outer diameters forming a transition, wherein the distal section includes two distal section components connected by an axially separable region. When the axially separable region is axially separated: (i) the proximal section of the proximal inner tube is slidable in a proximal direction through the stopping member until the transition in the outer diameter of the first distal section component attached thereto engages a stopping member prohibiting axial movement in the proximal direction; and (ii) the restricting element maintaining in position the second distal section component within the outer delivery tube.
