    摘要: Systems and methods of delivering and retaining a leadless medical implant to tissue, wherein a docking base and the implant are sequentially delivered to an implantation site. In a first stage, the docking base is delivered and deployed into tissue at an implantation site. In a second stage, the implant is navigated through the vasculature and coupled to the docking base. Various mechanisms for navigating the implant to the previously implanted docking base and coupling the implant thereto are described. Navigational mechanisms include advancing the implant over a proximally extending wire portion that is releasably attached to the previously implanted docking base, utilizing fluoroscopic visualization to guide the implant to a previously implanted docking base that is at least partially radiopaque and utilizing electromagnetism to guide the implant to a previously implanted docking base that is electro-magnetizable.
