    Abstract: A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12 -inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.

    Abstract: A method for forming a balloon for a dilatation catheter may utilize the steps of extruding a tubing preform of a polyester resin and then blowing the tubing into an oriented balloon, wherein the tubing preform is dried prior to blowing into the balloon form. Other process steps by which balloon cone and waist thicknesses may be reduced involve varying the axial tension and blowing pressure at several stages as a mold containing the balloon preform is dipped into a heating medium. Specifically, tubing of a thermoplastic material is placed in a mold and blown by pressurizing and tensioning the tubing and gradually dipping the mold into a heated heat transfer media so as to sequentially blow a first waist, a body and a second waist portion. The tubing is subjected to a relatively lower pressure while the body portion is blown than while the first and second waist portions are blown.

    Abstract: A substantially tubular member comprises a body. The body is constructed from a first material and has an external surface. At least a portion of the external surface has a predetermined pattern of a second material deposited thereon. The predetermined pattern of the second material is deposited on the at least a portion of the external surface by one or more printing processes such as solution coating, spray coating, thermal printing, piezo jet printing, contact printing and any combination thereof.

    Abstract: A balloon catheter comprises an inner tube, a medical balloon and an inflation lumen. The medical balloon is disposed about the inner tube and in fluid communication with the inflation lumen. A collapsible portion of the inner tube is constructed to collapse inward upon delivery of an inflation fluid to the medical balloon to secure the inner tube to the guidewire.
