Abstract: A method includes detecting, by an implantable medical device (IMD), attachment to the IMD of at least one implantable medical lead with at least one electrode; and triggering by the IMD, based on the detecting of the attachment to the IMD of the at least one medical lead, a device test sequence in which the IMD performs the following qualification tests over an evaluation period: detecting an impedance for at least one electrical path that includes the at least one electrode to determine a connection status of the IMD to the at least one electrode; and comparing EGM (electrogram) amplitudes of the patient over an EGM test period against a predetermined threshold.

Abstract: Devices, systems, and methods for treating vessel openings are disclosed herein. According to some embodiments, a device for treating a vessel opening comprises a housing configured to be positioned within an opening in subcutaneous tissue proximate the vessel opening. The housing can comprise an inner wall and an outer wall. The inner wall can define a first lumen configured to receive an elongate member therein and the inner and outer walls can define a second lumen configured to receive an adhesive. The outer wall of the housing can define one or more apertures extending radially from the second lumen to an environment external of the housing. The device can comprise an actuator configured to be received within the second lumen. Movement of the actuator can force the adhesive to move through the aperture to the external environment and into an extravascular space within the subcutaneous tissue proximate the vessel opening.
