Two-Stage Delivery Systems and Methods for Fixing a Leadless Implant to Tissue
First Claim
1. A method of delivering a leadless medical implant to tissue at an implantation site within a patient, the method comprising the steps of:
- percutaneously introducing and advancing a docking base through the vasculature of the patient to an implantation site;
deploying an anchor of the docking base into tissue at the implantation site;
percutaneously introducing and navigating a leadless medical implant through the vasculature to the implanted docking base; and
coupling the leadless medical implant to the docking base to retain the implant to tissue at the implantation site.

Abstract
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.
