US Patent 11406416 Joint assembly for vasculature obstruction capture device

A joint assembly for an endovascular device, comprising a shaft comprising a main body and an enlarged end, a proximal strut comprising a slot, wherein the slot engages the enlarged end of the shaft and a locking collar comprising a proximal face and a distal face, and at least partially covering the enlarged end of the shaft and the slot of the proximal strut, such that the locking collar constrains the proximal strut such that the proximal strut cannot disengage from the enlarged end of the shaft when the joint assembly and the clot retrieval device is under load.
