Abstract
Abstract A dilating and support apparatus with disease inhibitors and methods for use is disclosed that is particularly useful for repairing and/or serving as a conduit for body passageways that require reinforcement, dilatation, disease prevention or the like. Such apparatuses are utilized to deliver a therapy, that therapy being from a family of devices, drugs, or any of a variety of other elements to a specific location within the body. The instant disclosure provides a system of combining a novel radial deployment and/or drug delivery therapy with existing balloon dilatation therapy into one device. This combination will yield a significant decrease in cost to the healthcare system as well as providing a therapy to the patient with increased safety and efficacy. Further, the instant invention provides a novel and improved platform for synthetic/tissue interface between the device and the body.
