Abstract

Embolization coils are used for conditions such as Arteriovenous Malformations (AVMs)/Aneurysms and Major aortopulmonary collateral arteries (MAPCAs) by occluding target/unwanted vessels. These devices are typically made of metals and while this allows for monitoring under fluoro during insertion, the device can create metal artifacts on CT and MR follow up scans that degrades image quality. Most patients get up to 15 or 20 coils surgically inserted inside their body from childhood to adulthood and that presents a challenge to radiologists. The focus is to limit the number of devices in the body that may reduce CT and MR image quality for scans taken throughout a patient's life. Our current dominant product concept is a coil, similar in shape and insertion method to what is used currently by physicians, but the device will not be made of metal. It will be made out of a non-radiopaque material such as a fast swelling polymer (NIPAAm) and will be laced with a radiopaque material, such as barium sulfate (contrast agent), that will degrade into the body after a certain period of time. So, the physician can monitor the coil with a fluoroscopy device during deployment, but the device will not create artifacts or degrade image quality for follow-up scans with CT and MR.
