In one embodiment, the device has a substantially flat valve unit and a substantially flat filter unit. In another embodiment, the device has at least one open umbrella deployed configuration. In one aspect, the device has a unitary construction with one umbrella canopy with one or more filter areas with flaps allowing unidirectional blood flow. In another aspect, the device has a valve unit and filter unit, the umbrella canopies oriented in opposite directions, and the valve unit “closes” and opens to allow blood to flow to one direction. Also provided is a temporary valve system, including a core having an inverted delivery configuration and everted deployed configuration, that may be used with or without a filter unit, and a method of deployment.
A percutaneous temporary valve system, comprising a temporary valve, a central core, and a sheath for containing and delivering said temporary valve and central core;
A method of deploying a temporary valve comprising:
A percutaneous temporary valve-filter device, comprising a valve structure impermeable to blood and a filter structure permeable to blood but impermeable to emboli, said valve-filter device designed for simultaneously regulating flow of blood and collecting emboli.
A method of deploying a temporary percutaneous valve-filter device, comprising:
