    摘要: The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages. The present disclosure not only provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages, but the present disclosure also provides devices and method for assisting the guidewire in penetrating an occlusion, devices and method for using a sealable valve in the tip of the balloon catheter to reduce the overall size and diameter of the balloon catheter, thereby allowing the balloon catheter to penetrate smaller size blood vessels and devices. Given the persistence of coronary artery disease (CAD) and peripheral artery disease (PAD), there remains a need for improved therapeutic methods designed not only to reduce vascular blockages in the short term, but also to prevent future complications such as restenosis.

    摘要: A nested balloon is provided where each balloon is formed from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, nested balloon is provided with layers that allow for slipping, such that the balloon has a very high pressure rating and toughness, yet excellent folding characteristics. Methods for producing such nested balloons using existing balloon forming equipment are also provided. The nested balloons can have layers with low-friction surfaces. The nested balloons are preferably manufactured using a variety of methods.

    摘要: A measuring balloon has an inner bulbous balloon formed from a non-compliant or semi-compliant material and has a central smaller diameter inner waist and two larger diameter bulbs on each side of the inner waist. A compliant outer waist bladder is located on the outside of the inner bulbous balloon adjacent to the inner waist and is inflated via a separate inflation lumen. The inner balloon is inflated at a higher pressure to dilate stenotic aortic valve leaflets, and provide alignment and positioning of the measuring balloon across the aortic annulus. The bladder waist is inflated to a lower pressure to make contact with the aortic valve annulus. Marker bands positioned on the outside of the measuring balloon provide determination of annulus diameter and ovality.
