Medtronic Reveal LINQ™ In-Office 2 (RIO 2) Study United States

RIO 2 is a two arm, randomized, prospective, un-blinded, multicenter, non-significant risk
study. The primary objective for RIO 2 will be assessed by randomizing subjects to receive
their LINQ™ insertion in the office setting or in the traditional hospital environment.
Moving the LINQ™ insertion procedure to the office setting is not expected to decrease the
complication rate compared to in hospital insertion procedures, however, moving the LINQ™
insertion procedure out of the traditional hospital setting may benefit the patient and
reduce the burden to the healthcare system.

Inclusion Criteria:

1. Patient is indicated for continuous arrhythmia monitoring with a Reveal LINQ™
Insertable Cardiac Monitor

2. Patient is 18 years of age or older

3. Patient is willing to undergo ICM insertion procedure outside of the cath lab, OR, EP
lab setting with only local anesthetic

4. Patient is willing and able to provide consent and authorize the use and disclosure of
health information

5. Patient is willing and able to comply with the protocol including the required
follow-up

Exclusion Criteria:

1. Patient has unusual thoracic anatomy or scarring at the implant site which may
adversely affect the success of the implant procedure

2. Patient has reduced immune function or is otherwise at high risk for infection per
physician discretion

3. Current therapy with immunosuppressive agents or chronic steroid use e.g. Prednisone
greater than 20mg per day

4. Patient requires hemodialysis

5. Patient with active malignancy or history of chemotherapy or radiation treatment

limited to pneumonia, urinary tract, cellulitis, or bacteremia.

6. Patient has had major surgery (in the past 6 months)

7. Patient has undergone a procedure which required central venous or intraarterial
access (e.g. AF/VT ablation, EP study, coronary angio) within the last 3 months or is
scheduled for such a procedure while enrolled in the study.
