Dilating and support apparatus with disease inhibitors and methods for use
First Claim
1. A method for dispensing an agent into body tissue defining a passageway of a body for treatment of cardiovascular disease comprising:
- positioning a porous tubular braid having individual yarns, comprising a contact-dispensable agent in contact with all of the individual yarns, at a target site within the passageway of the body the porous tubular braid defining an open interior;
expanding the tubular braid against the body tissue by a separate radially-expandable element within the open interior or the tubular braid causing the tubular braid to make intimate contact with the body tissue;
dispensing the agent from the tubular braid into the body tissue;
contracting the radially-expandable element and the tubular braid from the body, and removing the radially-expandable element and the tubular braid from the body.

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.
