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.

A catheter structure, such as a balloon catheter (), guidewire, or the like, with markings () perceptible outside of the vasculature is for use in determining at a location external to the body the position of the catheter structure relative to a treatment area. Related kits are also disclosed.

A catheter includes a wave guide for transmitting ultrasonic energy from a transducer, and which is also rotated to facilitate enhanced disruption of the concerned obstruction in a transverse direction. Embodiments of waveguide include distal anchors that help focus the energy transmitted to a treatment site, and may also include a deployable filter that may open distal of the obstruction to capture any dislodged debris. Selectively inflatable balloons may cordon off a treatment site, and the wave guide may comprise a tube that may serve the dual purposes of inflating the balloon(s), as well as to transmit ultrasonic energy to an obstruction. A portion of an ultrasonic catheter may include plural curved portions to space an exposed portion of the wave guide away from the catheter body to enhance the vibratory action provided.
