A method for preventing a restenosis within a vessel wall requires a medicament be delivered at predetermined locations into the vessel wall and allowed to subsequently disperse in a predetermined pattern. To deliver the medicament, a catheter with an expanding member is advanced into the vasculature of a patient until the expanding member is located as desired. The expanding member is then expanded to force dispensers into the vessel wall to the proper depth. A medicament is then pumped through the dispensers to create a plurality of equally spaced, localized medicinal deliveries which subsequently disperse to medicate an annulus shaped volume within the vessel wall.

A balloon activated force concentrator for use in cooperation with an inflatable angioplasty balloon includes at least one elongated flexible panel, an elongated cutting blade mounted on the outside surface of the elongated flexible panel, and an elastic circular band attached to each end of the elongated flexible panel for securing the elongated flexible panel to an angioplasty balloon. Use of this balloon activated force concentrator requires mounting the device on an inflatable angioplasty balloon by inserting the distal end of the angioplasty balloon through one of the circular bands. The balloon activated force concentrator is then advanced over the balloon until the second circular band reaches the distal end of the balloon. At that point, the elasticity of the circular bands straddle the balloon to retain the activated force concentrator securely against the outer surface of the angioplasty balloon.

A method and device for injecting fluid into a treatment area of a vessel wall is provided herein. A first version of the device includes an inflatable balloon mounted on a catheter and a plurality of injectors extending outwardly and moving with the balloon. At least one fluid passageway connects each injector in fluid communication with a fluid source. During use of the device, the balloon is first positioned in a vessel proximate the treatment area. Next, the balloon is inflated to embed the injectors into the vessel wall. Subsequently, the fluid from the fluid source is introduced into the fluid passageway and through the injectors into the treatment area. A second version of the device includes a plurality of flexible tubes mounted between a multi-lumen catheter and a grommet. A push-pull wire is connected to the grommet and passed through a lumen of the multi-lumen catheter. The injectors are mounted on each of the flexible tubes.

A method and devices are provided for performing end-to-side anastomoses between the severed end of a first hollow organ and the side-wall of a second hollow organ utilizing transluminal approach with endoscopic assistance. In particular, the method utilizes a catheter, having a selectively operable cutter, which is introduced into the first hollow organ until the distal end of the catheter is substantially adjacent to the severed end of the first hollow organ. The severed end of the first hollow organ is positioned in proximity to the site for anastomoses on the side wall of the second hollow organ and the severed end is secured in sealing engagement with the side-wall, thereby defining a region of securement on the side wall of the second hollow organ. The severed end of the first hollow organ is preferably secured to the side wall of the second hollow organ by activating a corkscrew element in the catheter to penetrate the side-wall of the second hollow organ and hold the severed end of the first hollow organ in mating engagement with the side-wall of the second hollow organ. A plurality of clips can be applied to the seam between the first hollow organ and the second hollow organ.

The present invention, which addresses the needs described above, resides in an apparatus and method for coupling vascular apertures to a blood supply vessel in a manner that minimizes the time and operator dependent inconsistency in performing vascular anastomoses. In the coronary setting, this concept is fast and can be applied to both conventional and minimally invasive operative techniques. In the preferred embodiment, the present invention relates to an apparatus and method for facilitating end-to-side vascular anastomoses procedure, whereby the present invention acts as a coupling apparatus between a first, blood supplying hollow organ, e. g. the LIMA, radial artery, or a saphenous vein and the side wall of second hollow organ, typically one of the major coronary arteries, such as the left coronary artery (LCA), right coronary artery (RCA) or the circumflex (CX).
