US Patent 9943313 Detachable coil release system and handle assembly

A medical implant deployment system for placing an implant at a preselected site comprising a deployment system that includes a mechanical coupling assembly at the distal end of a delivery member that engages the proximal end of the implant and a release member having an extended configuration in which the release member cooperatively maintains the coupling assembly engagement with the implant proximal end and a retracted configuration where the release member allows the coupling assembly to disengage from the implant proximal end. An attachable handle assembly is provided to place the release member in the retracted configuration allowing the coupling assembly to disengage from the implant proximal end, thereby releasing the implant.
