Abstract: Devices and methods for removing a thrombus (clot) from a vascular structure of a living subject. An embodiment of a thrombus removal device comprises first and second annular members, the first annular member being adapted to slide over a guidewire placed in a vascular structure, the second annular member being coupled to the first annular member and having a suction flow path therethrough, the first annular member having an expandable mesh structure disposed at a distal portion thereof, the mesh structure being deployable to an expanded configuration by movement of an actuating element extending along the second annular member. An embodiment of a thrombus removal method comprises advancing the device to position the mesh structure downstream of the thrombus by sliding the first annular member over the guidewire, applying a suction force to the suction flow path of the second annular member, deploying the mesh structure, and retracting the device to cause the mesh structure to engage the thrombus.

Abstract: One embodiment provides a method implemented by a powered inflation device to prepare a balloon catheter for use during a medical procedure. In this embodiment, the method includes drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device, removing an amount of air from the balloon catheter during a second motorized operation of the inflation device, and injecting the amount of medical fluid from the inflation device into the balloon catheter during a third motorized operation of the inflation device to inflate a balloon located at a distal end of the balloon catheter. The powered inflation device may be a stand-alone device in one embodiment. In one embodiment, the powered inflation device is coupled to an angiographic injector system. When it is coupled to an angiographic injector system, the balloon inflation device and the injector system may be controlled by a common control panel, or console, in one embodiment.

Abstract: One embodiment of the invention provides a method to purge air or liquid from a powered injection system. In this embodiment, the method includes driving a first pumping device in a first operational mode to inject an amount of a first liquid medium through disposable tubing and a disposable valve, driving the first pumping device in a second operational mode to deform the disposable valve, and driving a second pumping device to inject an amount of a second liquid medium through the disposable tubing and the deformed valve. In one embodiment, the first pumping device comprises a first syringe, the second pumping device comprises a second syringe, and the disposable valve comprises an elastomeric valve.

Abstract: The present invention presents various novel approaches to solving the problems inherent in measuring biological pressures in high pressure systems. Thus, to protect a pressure transducer exposed to fluid flows at higher pressures than its overpressure rating, a novel valve is used that closes a protected leg in which the transducer is located. The various exemplary embodiments of such valves each have a high pressure input, one or more low pressure inputs, and an output. In operation, when a high pressure fluid flow occurs at a high pressure input, such valves automatically close the low pressure inputs. Alternatively, a novel transducer system is presented, which automatically limits the effective pressure sensed by a transducer to a certain maximum.
