About this trial

The goal of this clinical trial is to learn if the Arcevo LSA stent graft can safely and effectively treat patients that have an acute or chronic aortic dissection and/or aneurysm that involves the aortic arch and the descending thoracic aorta, with or without the involvement of the ascending aorta.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Acute, subacute, or chronic dissection that involves the aortic arch and the descending thoracic aorta, with or without involvement of the ascending aorta

Aneurysm that involves the aortic arch and the descending thoracic aorta, with or without involvement of the ascending aorta

Patient, or patient's legally authorized representative (LAR; in the secondary arm only), provides written informed consent prior to any study procedures

Patient's surgery occurs within 90 days of informed consent

Disqualifiers

Patient is pregnant, or planning to become pregnant during the course of the study; individuals of child-bearing potential must agree to use acceptable methods of contraception during the study

Patient has another medical condition (aside from the arch disease) that, in the opinion of the investigator, reduces the patient's life expectancy to < 2 years

Patient has an existing aortic stent graft device in the descending aorta that would interact with Arcevo™ LSA

Patient has a medical, social, or psychological problem that, in the opinion of the investigator, could impede the patient's ability to return for follow-up

Trial design

Design model

Single group

Treatments tested in this trial

  • Arcevo™ LSA Hybrid Stent Graft System

    Device

    The Arcevo LSA Hybrid Stent Graft System is an implantable aortic stent graft with LSA branch which is preloaded onto a delivery system and implanted during an open surgical procedure, or more specifically a total arch replacement procedure. The device is intended for use with a proximal surgical graft (not supplied). If additional coverage is needed, a protocol specified thoracic endovascular aortic repair (TEVAR) device may be used.
