EASYER (EpiAccess SYstem Registry) A Post Market Observational Registry

The Registry will be a prospective non-randomized single-arm trial of up to 150 patients
enrolled in up to ten (10) centers in the United States. The overall duration of the registry
is estimated to be 18 months per site. For the patients the registry duration will be from
the time of procedure until discharge from the hospital, estimated to be approximately four
(4) days.

Prior to enrollment, patients will be evaluated on the basis of the latest available data to
establish eligibility. Eligible patients will be considered enrolled in the registry after
written informed consent is obtained.

As EpiAccess is only used for the access portion of the procedure, the safety performance and
effectiveness endpoints are acute from the time of needle insertion until pericardial sac
access is achieved. Follow up clinical examinations will be performed according to
institutional standard of care. No special tests are required for this device.
