Renova embolization coil system is a medical device used in neurovascular interventions to treat cerebral aneurysms, which are bulges in the blood vessels in the brain that can potentially rupture and cause a stroke. The Renova cerebral aneurysm coiling is made up of tiny wire coils that are inserted into the aneurysm through a catheter and packed in tightly to prevent blood flow that would otherwise further weaken the vessel wall. The coils are detached from the delivery wire after implantation, creating a scaffold that encourages the formation of a clot which ultimately seals off the aneurysm.

One of the key features of the RenovaTM embolization coil system is its minimally invasive nature. Unlike open surgery, where a craniotomy is usually required to access the brain, this procedure only requires a small incision in the groin where the catheter is inserted. This leads to faster recovery times and fewer complications, which is especially important for patients who are frail or elderly. Another advantage of this system is its versatility in treating different types of aneurysms. This includes small or wide-necked aneurysms, which can be more challenging to treat with other methods. It also offers significant benefits to neurointerventionists, who are the physicians who perform these procedures. The detachable coils are designed with a unique detachment mechanism that allows for precise control during deployment, which reduces the risk of complications like coil migration or perforation. This also allows for better visualization during the procedure, as the coils can be repositioned or removed as needed.
