A noninvasive, hand-held, manual device (non-electronic) intended to mechanically break the connection between a vascular implantable device (typically a neurovascular or peripheral embolization coil or stent) and its deployment device (i.e., implant inserter or delivery wire). It is typically in the form of a handpiece, intended to be attached to the deployment device, with a mechanical switch for detachment. This is a single-use device.
