Abstract: A coronary artery check valve includes a stent configured to attach to an inner wall of a coronary artery of a living subject, and a tapered helical coil coupled to the stent and configured to regulate blood flow in the coronary artery. The coronary artery check valve is configured to prevent retrograde flow of the coronary blood supply during diastole by closing during systole of the heart when the tapered helical coil compresses longitudinally, and opening when the tapered helical coil expands longitudinally to permit blood flow into the coronary artery when a coronary pressure of the living subject drops below diastolic blood pressure.

Abstract: Apparatus and methods are described including identifying a subject as suffering from a condition that causes the subject to have elevated central venous pressure. In response thereto, a device is placed inside the subject's vena cava, and the device is deployed inside the subject's vena cava, such that, in a passive manner, the device reduces blood pressure within the subject's renal veins relative to the subject's central venous pressure. Other applications are also described.

Abstract: A method for delivering catheters, and stents composed of soft, compliant polymers through anatomical passages. These devices have a bulbous or enlarged anchorage end with a diameter greater than the rest of the catheter. To facilitate implant and delivery a pusher catheter or sheath with an internal lumen larger than the outer diameter of the catheter but smaller than the outer diameter of the bulbous or enlarged anchorage end is provided. The distal end of pusher catheter or the sheath physically engages the proximal end of the bulbous or enlarged anchorage end and applies an axial force to coaxially advance the catheter over a guidewire through anatomical passages. This method allows a physician to move the catheter to an anatomical site without the device exhibiting buckling due to axial force applied. Similarly, this delivery method will allow more force to be applied to the distal end of the catheter diminishing the likelihood of buckling.

Abstract: Devices, systems, and methods for the prevention of stroke. Devices and systems hereof comprise stents configured to fit within at least part of an artery extending from an aortic arch, and at least one component comprising struts for diverting emboli from entering an artery when the component is positioned at or near its ostium. The stents and the deflection component(s) are coupled in a linked configuration. Additionally, a retrieval system and methods of using the same are provided, the retrieval system comprising a sleeve catheter and a retrieval device slidably disposed therein. The distal end of the retrieval device comprises an attachment portion configured to engage a device positioned within an artery extending from the aortic arch.
