Abstract: 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.

Abstract: Method and devices for treating a physiologic condition of a patient using measurements of pressure of an interstitial space of a patient as an indicator of required therapy.

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.

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: 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.

Abstract: Devices and methods of treating conditions cause or exacerbated by excessive fluid pressures or retentions, such as pulmonary hypertension, that involves shunting excessive fluid pressure from one bodily chamber or vessel to another bodily chamber or vessel.

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: 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: Establishing connections across tissue walls used to create shunts or similar passageways are formed using methods and devices that utilize magnets for navigation and location of devices on opposite sides of the walls. Various tools are provided that optimize the uses provided by the magnets.
