A method for imaging a delivery system is disclosed. The method includes positioning an implantable device within a delivery apparatus. The implantable device has a first base material that includes a mixture of which a first radiopaque material is a component and/or coating at least a portion of the first base material with a coating of which a first radiopaque material is a component. The delivery apparatus may be positioned relative to an imaging device. An image produced by the imaging device may be analyzed. It may be determined whether the delivery apparatus is ready to deploy an implantable device.
