Benefits of technology

The technology described in this patent involves adding a layer of braid on top of an angioplasty balloon during a procedure that reduces damaging blockages in arteries. This added layer causes small cracks in the hardened fatty substance (plaque) along the walls of the vessels where it can accumulate. These breaks help deliver drugs deeper into the plaque and make them less prone to come back again after treatment. Additionally, the braid helps improve how well the medication sticks to the plaque and prevents some of it from being flushed out with blood.

Problems solved by technology

The technical problem addressed in this patent is how to create a tool for delivering medicine or other substances to the blood vessels without leaving behind a large amount of plaque or damaging the surrounding area. The solution involves a thin layer of braid that can be inserted into existing angioplasty devices to provide temporary protection against restenosis (the formation of new blockages). The braid can be made of monofilament or mulfilament braid, depending upon the desired application. The patent includes various methods for inserting and removing the braid, including placing it over the balloon of the device and allowing for controlled expansion and contraction.

Embodiment Construction

[0050] The present invention is used for intervention into the tubular channels (arteries, veins, biliary tract, urological tract, gastrointestinal tract, stents, grafts, sinuses, nasopharynx, heart, ears, etc.) or hollow cavities (stomach, gall bladder, urinary bladder, peritoneum, etc.) of the body. Further, it may be used in iatragenically created passageways. It is particularly convenient to use in an environment of an operating room, surgical suite, interventional suite, Emergency Room, patient's bedside, etc. One preferred embodiment of this device is that the elongate, flexible shaft is inserted into the tubular channel or hollow cavity of the body usually through pecutaneous access or via a surgical incision. In the case of lumens that enter and exit the body naturally, the device may enter through one of those entry or exit paths (i.e. rectal opening, mouth, ear, etc.). Once the device is in the preferred location (that being where the narrowing or obstruction is located), ...

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.
