  • Publication number: 20250090356
    Abstract: The present teachings provide a medical system for delivering and deploying a medical implant, and the method of using thereof. Specifically, one aspect of the present teachings provides a medical system having an implant with an engagement loop, and a delivery system having an engagement wire and an engagement mechanism. During implant delivery, the engagement wire engages the engagement loop of the implant. The engagement wire further interacts with the engagement mechanism in order to prevent unintended disengagement of the engagement loop from the engagement wire. The present teaching also provide an implant release mechanism that is configured to break away from the implant pusher shaft. Specially, one aspect of the present teaching provides that the implant release mechanism being of one unit with the implant pusher shaft. To release the implant, a clinician simply breaks away the implant release mechanism from the rest of the implant delivery system.
