Abstract
A temporary percutaneous valve-filter device having valve portions non-porous to blood and filter portions non-porous to emboli but at least in part porous to blood. 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.

10. A method of deploying a temporary valve comprising:
-
providing a sheath containing a temporary valve having a central core, said temporary valve comprising a valve body and plurality of lines, wherein said plurality of lines connects a peripheral rim of said valve body to said central core, and said central core has a folded delivery configuration forming a folded central core wherein said folded central core is inverted within said sheath and connected to said sheath; pushing said folded central core and said temporary valve from said sheath using a pusher, while said sheath remains static; and everting said central core into a deployed configuration, said temporary valve thereby assuming a deployed configuration. - View Dependent Claims (11, 12, 19, 20, 21, 22)

26. A method of deploying a temporary percutaneous valve-filter device for use in percutaneous cardiovascular procedures, comprising:
-
introducing into a vessel, a system comprising; a valve-filter device mounted on a first delivery device having a lumen, said valve-filter device having a radially collapsed delivery configuration, said valve-filter device comprising;
a temporary valve having a central core, and said first delivery device for containing and delivering said temporary valve and said central core,said temporary valve comprising a valve body and a plurality of lines, each line of said plurality of lines connected at a first end to a rim of said valve body and at a second end to said central core;
said central core having an inverted delivery configuration and connected to said first delivery device;advancing said valve-filter device to a target site; deploying said valve-filter device from said first delivery device; and expanding radially said valve-filter device to a working configuration designed for simultaneously regulating flow of blood and collecting emboli. - View Dependent Claims (27, 28)
