The RenovaTM Aneurysm Endovascular Coiling is intended for the endovascular embolization of intracranial aneurysms and other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae.

RenovaTM aneurysm endovascular coiling is a minimally invasive surgical procedure that is used to treat brain aneurysms. An aneurysm is a weakened area in the blood vessel wall caused by a bulge or ballooning. If left untreated, the aneurysm can rupture, resulting in a life-threatening hemorrhage. Endovascular coiling involves inserting a catheter through the patient’s groin and threading it up to the brain. The surgeon then uses the catheter to introduce tiny platinum coils into the aneurysm, filling it up and preventing blood flow into the weakened area of the blood vessel. The coils encourage the formation of a blood clot around the aneurysm, sealing it off from the rest of the circulation. The open loop configuration of the coils used in endovascular coiling allows them to conform to different aneurysm shapes, minimizing compartmentalization. Compartmentalization occurs when the coil herniates, or protrudes from the aneurysm, creating separate compartments within the aneurysm where blood can pool and potentially cause a rupture. The smaller first 1.5 loops of the coil are 25% smaller than the stated secondary coil diameter, reducing the risk of coil herniation. RenovaTM also utilizes an open center design, which allows for concentric filling. This means that the coils can be placed tightly together, filling the aneurysm completely and effectively blocking blood flow. This design can help prevent the coils from migrating or moving around within the aneurysm, ensuring that the aneurysm remains sealed off.
