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.

Abstract: An adjustable vascular graft with a user-customizable reduced inner diameter is provided. The graft includes a flexible tubular body having open ends and a plurality of receivers in a sidewall thereof, which may be arranged in two circumferentially spaced rows of receivers. The receivers may take the form of ringlets, eyelets, loops, or holes, which may be provided in a reinforced region of the graft sidewall, and which may be radiopaque. A suture passes through the plurality of receivers, the suture having first and second free ends capable of being pulled, and which suture may also be radiopaque. Tensioning or tightening the first and second ends of the suture reduces an inner diameter of the corresponding portion of the tubular body of the graft, thereby allowing for the custom reduced inner diameter and a resulting flow restriction to be provided. Related methods are also disclosed.
