Abstract: An expandable bifurcated stent is formed of a main body and a first branch. The body wall is made up of interconnected stent members that define a plurality of cells, at least one of which is a side opening. The first branch body extends from the body wall from at least two regions adjacent the side opening. At least one stent member adjacent the perimeter is bioabsorbable.

Abstract: A catheter system comprises a catheter and a reinforced catheter balloon. The catheter balloon has at least one cone portion and a working portion. The catheter balloon has in cross section the at least one cone portion has a polygonal shape with sides and corners. The balloon is disposed about a longitudinal axis and has an inflated state and an uninflated state. In the uninflated state the working portion of the balloon forms wings which have tips that are circumferentially aligned with the corners of the cone portion.

Abstract: A catheter comprises a first catheter shaft comprising a wall. The wall comprises at least one section of electroactive polymer having an actuated state and a non-actuated state and defines a first lumen. In the actuated state the first lumen haves a first diameter and in the non-actuated state the first lumen haves a second diameter, the first diameter being different than the second diameter.

Abstract: A catheter system comprises a catheter comprising a distal portion, a proximal portion and an inner shaft. The inner shaft comprises a medical device receiving region for receiving and carrying a medical device. The retaining device is at least partially constructed of an electroactive polymer. The retaining device is located on or adjacent to the medical device receiving region. The electroactive polymer of the retaining device has an activated state and an inactivated state. The retaining device is capable of retaining a medical device to the catheter and releasing the medical device from the catheter by transitioning between the activated state and the inactivated state.

Abstract: A catheter comprising an outer shaft comprising a first section of electroactive polymer. The first section of electroactive polymer affecting either the flexibility of the catheter or the steerability of the catheter.

Abstract: The present invention is directed to variations of catheter configurations, wherein the outer shafts have been supplemented with electroactive polymer (EAP) material to modify the performance characteristics of the catheter.

Abstract: Composite fiber reinforced balloons for medical devices are prepared by applying a web of fibers to the exterior of a preformed underlayer balloon, encasing the web with a matrix material to form an assembly, and inserting the assembly into a preformed outer layer balloon to form the composite balloon.

Abstract: Described herein are medical balloons which contain one or more material regions that are configured to cause the balloons to preferentially fold into predetermined orientations upon deflation.

Abstract: A catheter tip has an outer surface section, an inner surface section, a spatial configuration and at least one segment of electroactive polymer. The inner surface section defines a guide wire lumen. The electroactive polymer has an actuated state and a non-actuated state. In an actuated state, the electroactive polymer alters the spatial configuration of the catheter tip.
