An apparatus for manufacturing atherectomy torque tubes includes a mechanism for rotating a tube liner about its longitudinal axis at a rotational velocity. A carriage is translatably positioned along the longitudinal axis. A mechanism for winding a wire about the tube liner is mounted on the carriage. A mechanism for coating the tube liner with an epoxy material is also mounted on the carriage. In a preferred embodiment, wire is wound onto the tube liner inside a reservoir of urethane epoxy bath which is moved along the tube liner. A laser sensor measures the coated tube to provide a signal representative of the final outside diameter of the tube and a computer uses this signal to control the angular velocity of the rotating tube liner and the linear velocity of the carriage which moves the wire winding and coating mechanism along the tube. The computer also uses the signal to control a pressurized gas source which extrudes proper amounts of epoxy material out of the reservoir to coat the tube as the reservoir moves along the tube liner.

A device for folding a balloon of a balloon catheter during balloon deflation includes a band and a plurality of elongated fingers that are attached to the band. The band is formed with a tab and a notch and the length of the band corresponds to the diameter of the catheter tube. The band is folded into an annulus to interlock the tab with the notch. The annulus is attached to the catheter tube of the balloon catheter with the fingers extending over the balloon in a substantially same axial direction. In operation, the fingers are moveable between an unstressed configuration, when the balloon is deflated, and a stressed configuration, when the balloon is inflated. In a stressed configuration, the fingers urge against the balloon and are biased toward the stressed configuration to return to an unstressed configuration.

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 of manufacturing a folding balloon catheter for use as an angioplasty device, wherein the balloon catheter has atherotomes attached to the exterior of the balloon, includes inflating a balloon to its expanded state. A plurality of patches of a curable elastomer adhesive are then applied at selected locations on the outside surface of the inflated balloon, and an atherotome is attached to the balloon at each of the patches. The inflated balloon, with attached atherotomes, is then partially cured to more firmly attach the atherotomes to the balloon. The balloon is then deflated to a contracted configuration in a manner which forms a plurality of flaps in the balloon between the atherotomes. The deflated balloon is then cured to completion to establish a permanent set in the flaps which enable the balloon catheter to be repeatedly inflated and deflated during operation between predictable expanded and contracted configurations.

A stenotic dilitation device includes a plurality of elongated atherotomes with cutters embedded in a substrate mounted on the outer surface of a flexible balloon along predetermined crease lines. The atherotomes are aligned along the longitudinal axis of the catheter. The ends of the balloon are attached to a hollow catheter tube over fluid ports in the catheter which establish fluid communication between the catheter and the internal chamber of the balloon. Fluid flow into and out of the chamber will inflate and deflate the balloon. When the balloon is deflated, retraction of the atherotomes toward the longitudinal axis of the catheter causes the creases and lines to form flaps of the balloon membrane material between adjacent atherotomes. In such deflated configuration, the flaps, rather than the cutters of the atherotomes, contact the vessel wall as the device is manipulated into position adjacent a stenotic site. On inflation of the balloon at the stenotic site, the atherotomes are urged against the stenosis to incise the stenosis.

A catheter balloon is provided for medical dilation procedures which is formed from a polymeric composite having an enhanced integrity. The balloon comprises an expandable central body and two tapered termini positioned at opposing ends of the body which are formed from a structural layer of continuous polymeric materials characterized as biaxially oriented in the body, but not in the tapered termini. A layer of an imide-containing polymer is provided external to the structural layer of the tapered termini to coat the termini and strengthen or otherwise enhance the integrity of the termini not having a biaxial orientation. The imide-containing polymer coating may further be continuously extended to the body of the balloon. The imide-containing polymer is applied to the structural layer of the balloon, in a liquid state and heat cured over time to produce a high-integrity coating.

A device for injecting medication into a vessel wall includes an inflatable balloon mounted on a catheter. Additionally, a plurality of tubular fluid passageways are longitudinally mounted on the balloon, and a plurality of injectors are mounted on each tubular passageway and in fluid communication therewith. During use of the device, the balloon is first positioned in a vessel. The balloon is then inflated to embed the injectors into the vessel wall. Next, a fluid medicament is introduced through each of the fluid passageways for further infusion through the passageways and through the injectors into the vessel wall.

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.

An apparatus and method of operation are disclosed for using an expandable balloon catheter to perform a combination angioplasty and atherectomy procedure on a stenotic blood vessel. The expandable balloon has a plurality of atherotomes attached to its outer surface, and longitudinal, transverse, or rotational oscillatory motion is imparted to the atherotomes to assist in incising the stenotic tissue, prior to or during dilatation of the stenotic segment of the blood vessel.
