摘要： A shunt is described that expands to an hourglass shape. As the shunt expands, both of its ends radially flare outwards relative to its middle section and the length of the shunt foreshortens, which causes the flared ends to engage the tissue surrounding a puncture or aperture within a patient's tissue.

摘要： A variety of methods and devices for manipulating tissue using stents and shunts that foreshorten when expanded. Many of the devices have ends that expand radially more than a center portion of the device, creating an hourglass or rivet shape that is useful for anchoring the device or putting a squeezing force on the tissue.

摘要： Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.

摘要： Disclosed herein are devices and methods for creating a shunt between two vessels or lumens within a patient. While these devices and methods are generally described with regard to treatment of hypertension (e.g., pulmonary arterial hypertension) and/or right heart failure/disfunction, they can be used with a variety of different vessels and lumens for other purposes. The devices include puncturing guidewire embodiments that can more accurately pierce two vessels, as well as snare catheter designs that can prevent unwanted damage from a puncturing guidewire.

摘要： Described herein are improved blood pumping devices, including improved intra-aortic balloon pumps and ventricular assist devices. The pumping efficiency of either device may be improved with the use of one or more valves, counter pulsation balloons, non-compliant tubular structures, secondary pumping balloons, and similar components.
