Abstract: 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.

Abstract: 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.

Abstract: Several embodiments and methods are described for draining a lymphatic system for therapeutic purposes. The lymphatic draining can be performed by removal of fluid from the lymphatic system via a needle, a catheter, an access port, a reservoir, a shunt, or a combination of these devices. The drainage devices can be configured for use during only a single procedure or for reoccurring procedures.

Abstract: Several embodiments of a catheter are described, having a balloon configured to slowly inflate and then quickly deflate to create an area of low pressure in the vessels. The balloon can be cycled near the vessels of the kidneys, thereby helping to draw out blood from the kidneys and enhance fluid processing to the bladder.

Abstract: Renal and urine collection system interventions are provided that improve kidney function by manipulating pressures and/or infusing therapeutic agents in the renal pelvis of the kidney or kidneys. Setting a vacuum and/or infusing therapeutic agents in the renal pelvis results in increased glomerular filtration rate, general solute clearance, and free water excretion via the kidney through the urinary tract and is useful for treatment of CHF, ADHF, AKI, CKD, and many other conditions characterized by fluid overload by reducing fluid buildup. The fluid drawn from the renal pelvis or pelvises is delivered to an external or implanted reservoir or to the bladder using flow manipulation mechanism such as one-way valves, occlusion balloons, multi-lumen catheters, and other mechanisms. Pumps are provided for use in establishing the vacuum pressures that are either manual or motorized.

Abstract: 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.
