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： Low profile biopsy tools and methods that allow relatively large biopsy samples to be taken. The biopsy tools have a first configuration that allows for atraumatic navigation to a targeted lesion, and a second configuration in which a distal end of the biopsy tool expands to take a large tissue sample. The tissue sample may then be retracted into a sheath or other containment feature and removed at a reduced diameter. Also included is an anchored guidewire usable to practice method for navigating a biopsy tool to a targeted lesion after an endoscope has been removed.

摘要： Devices and methods of treating fluid retention caused by congestive heart failure or other conditions resulting in edema, lymphoedema, or significant fluid retention (e.g., deep vein thrombosis, cellulitis, venous stasis insufficiency, or damage to the lymphatic network) are described. Specifically, a treatment device is used to create a passage or cannula between the lymphatic system (or other area of the body) and an external drainage device. This device can be only temporarily located in the patient or can be implanted within the patient for longer periods of time. The physician can safely and reliably remove excess fluid from the body via the device and optionally inject other treatment agents.

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： 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.
