Patent number: 9480479Abstract: A vaso-occlusive delivery system includes a vaso-occlusive coil, delivery wire assembly, and a link. The vaso-occlusive coil defines a coil lumen and has first and second coil windings defining a coil opening therebetween. The delivery wire assembly defines a delivery wire lumen, and includes an electrolytic detachment zone, a delivery wire conduit, and a delivery wire attached to the delivery wire conduit and extending through the delivery wire lumen distal of the delivery wire conduit. The link defines a link lumen and has link body including a proximal end of the link body defines an link opening in communication with the link lumen and a distal end of the link body includes a link detent extending radially from the link body, through the coil opening, securing the link body and the delivery wire assembly to the vaso-occlusive coil.Type: GrantFiled: August 12, 2014Date of Patent: November 1, 2016Assignees: STRYKER CORPORATION, STRYKER EUROPEAN HOLDINGS I, LLCInventors: Hancun Chen, Richard Murphy, Jimmy Dao, Justin Vo
