Abstract: A composite medical balloon includes a base balloon with first and second tapered portions (108) and a barrel portion (106) therebetween. The base balloon includes one or more fiber layers. A hybrid layer is applied over the base balloon, such as over the fiber layer. The hybrid layer includes a tube (70) for covering the barrel portion (106) and a spiral wrapping (80) for covering one or both of the first and second tapered portions (108). Related methods of forming of such a balloon are also disclosed.

Abstract: A re-entry device for recanalization of a vessel using a subintimal technique. A catheter (10) includes a first inner lumen (14) extending to a distal end portion (12b) of the catheter, the distal end portion including an angled tip (20) having a distal open end (20a). An elongated stylet (24) is located in the first inner lumen, the stylet having an angled distal end portion (24a) forming a needle. An actuator (26) at a proximal end portion (12a) of the catheter is for advancing the stylet from a retracted position within the catheter to a deployed position projecting from the distal open end of the angled tip for penetrating a wall of the vessel.
