IMPEDANCE-BASED VERIFICATION FOR DELIVERY OF IMPLANTABLE MEDICAL DEVICES

A device for delivering an implantable medical device (IMD) includes an elongated member and a deployment bay configured to house the IMD, the deployment bay defining a distal opening for deploying the IMD out of the deployment bay. The device includes a first electrode located inside the deployment bay during intravascular navigation, a second electrode, and impedance detection circuitry configured to deliver an electrical signal to a path between the first electrode and the second electrode through at least one of a fluid or tissue of the patient. The device also includes processing circuitry configured to determine an impedance of the path based on the signal and control a user interface to indicate when an impedance of the path indicates that at least one of the IMD or the distal opening is in a fixation configuration relative to the target site of the patient.
