FACING ANOTHER AORTIC ARCH SURGERY?

BlueGradientOnly.png

Have you had an aortic arch surgery in the past?

 

You probably know that you are at risk of needing additional surgeries in the future.

 

Having a prior aortic arch surgery and/or other risk factors can reduce your treatment options for another aortic arch surgery.

The TRIOMPHE Study is now enrolling patients at sites across the US to investigate the NEXUS™ Aortic Arch Stent Graft System. This innovative device is specifically designed for a much less invasive procedure. 

ABOUT THORACIC AORTIC ARCH DISEASE

ProductFade_edited.png

The NEXUS™ Aortic Arch Stent Graft System was specifically engineered for minimally-invasive total arch repair to overcome the challenges of the aortic arch anatomy.

 
NEXUS™ is delivered by traveling through your vascular system using fluoroscopic guidance (x-ray pictures), starting with a small incision or needle puncture near your groin (inner thigh). This delivery method is called an endovascular approach. 

 

NEXUS™ is designed to make a minimally-invasive repair possible for more patients while reducing the risks of surgery.

• Neurologic complications such as lipothymy (fainting) or encephalopathy brain disease that alters brain function

• Obstruction/Occlusion - no movement or blockage

• Pain

• Paralysis including vocal cords and diaphragm – immobilization of one or more parts of the body

• Paraparesis - partial paralysis of both legs

• Paraplegia - paralysis of the legs and lower part of the body

• Pericardial tamponade – when fluid in the pericardium (the sac around the heart) builds up resulting in the compression of the heart

• Perforation of a vessel wall - hole made by piercing

• Peritonitis - inflammation of the tissue that lines the inner wall of the abdomen

• Pseudoaneurysm - collection of blood that forms between the two outer layers of an artery

• Pulmonary complications and subsequent attendant problems – complications pertaining to lungs

• Renal insufficiency/failure – a condition in which the kidney loses the ability to remove waste and balance fluids

• Rupture of a vessel - break or burst of the aorta

• Ventricular fibrillation – rapid inadequate heartbeat

• Ventricular tachycardia – when the lower chambers of the heart (ventricles) beat very fast

• Vessel damage – injury to vessel

• Wound complications – often causes delay in healing including when the edges of the wound no longer meet (dehiscence) or a bacterial skin infection (cellulitis).

In addition to the aforementioned adverse events, several stent graft complications may occur. Including but not limited to: improper placement; incomplete deployment; inadequate apposition, migration; graft twisting or kinking; wear; dilatation; erosion; collapse of the component; breakage of the device suture or stent; insertion and removal difficulties; puncture and perigraft flow (flow outside of the graft lumen). There may be other potential risks that are unforeseen at this time. The occurrence of the above listed risks may lead to the need for a repeat procedure, emergency surgery, or death. Your study doctor has more detailed information on the risks of treatment with the NEXUS™ Aortic Arch Stent Graft System, including a complete list of warning, precautions and potential Side Effects/Adverse Events (AEs). You should talk to your study doctor about any side effects or allergic reactions that you have while taking part in the study.




What if I join the study and decide I do not want to participate anymore?


You may decide to stop participating in this study at any time. If you decide to withdraw from this clinical research study, you will be asked to participate in a limited capacity allowing your medical status to be followed by telephone contact, medical chart review, or by other agreed upon methods. If you decide not to continue participation in a limited capacity, your study doctor will not access your medical record or other confidential records for new purposes related to the study; however, study data collected prior to your withdrawal may be reviewed and publicly available records may be consulted prior to or after you withdraw. If you decide to stop taking part in this clinical research study, you must tell your study doctor as soon as you decide to stop. Regardless if you stay in the study or not and you received a study device, regular follow-up with a doctor, such as your primary care physician, for the rest of your life is important. Your doctor will want to make sure the study device is working properly even if you are not showing any symptoms.




How long does the study last?


It is estimated the entire study will take seven (7) years; however, your participation in the clinical research study will last about 60 months. You will need to visit the doctor’s office for study follow-up visits approximately seven (7) times over the course of the study.




What does the NEXUS™ device involve?


A stent graft is a self-expanding frame that is covered with a material intended to seal the vessel walls. The NEXUS™ Aortic Arch Stent Graft System is delivered to the diseased area of your aorta by traveling through your vascular system using fluoroscopic guidance (x-ray pictures), starting with a small incision or needle puncture near your groin (inner thigh). This delivery method is called an endovascular approach. The NEXUS™ Aortic Arch Stent Graft System has two parts (Figure 1) and one optional part. All will be delivered using the endovascular approach. The NEXUS™ Aortic Arch Stent Graft System is intended to seal the diseased portion of your aortic arch.




How many people can participate in the study?


Up to 100 patients will take part in this clinical research study at up to 30 different locations in the United States and up to one (1) location outside of the United States (New Zealand).




What are the benefits of participating in this study?


There are no guaranteed benefits from participation in this study. It is possible that after the NEXUS™ Aortic Arch Stent Graft System opens and expands to the final shape of the area above and below the diseased area of the aorta may help treat your condition, which may reduce the need for you to undergo further procedures but there are no guarantees. It is possible that by participating in this study your condition may improve or that this study may be helpful in developing a new therapy for others with similar illnesses. Even if you do not benefit directly from this research, knowledge gained from the study will contribute valuable information to researchers and doctors in the treatment of aortic arch disease and conditions.




How much will it cost?


You are responsible to pay for any items or services that are standard of care (that is, part of routine medical care) for your condition; and Endospan is charging for the NEXUS™ Aortic Arch Stent Graft System. To the extent you have insurance that pays for any routine medical care, you are responsible for any insurance copays and deductibles.
