- NOTE: MRI compatible knee replacements, hip replacements, stents, etc. may be
included as long as the labeling of these devices allow MRI scans conducted per
this protocol

- NOTE: MRI compatible mechanical, prosthetic, and bioprosthetic heart valves may
be included as long as the labeling of these devices allow for MRI scans
conducted per this protocol

- NOTE: Non-removable dental implants may be included

- Have a lead extender, adaptor, or capped/abandoned lead

- Be unable to fit in MRI bore, i.e., subject will come into contact with the magnet
façade inside the MRI bore.

Summary
Brief summary
This is a clinical investigational plan (CIP) for the "Clinical Study to Confirm MRI Safety
and Effectiveness Using SJM Cardiac Rhythm Management Systems (ASSURE MRI)". This study
intends to enroll patients who meet standard bradycardia or tachycardia indications and have
already been implanted with one of the SJM device/lead combinations listed in this protocol.
The objective of this study is to confirm the safety and effectiveness of each of the four
SJM device/lead combinations in an MRI environment. This clinical investigation is sponsored
by St. Jude Medical.
