A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, has a bent flexible wire mesh (1) with elasticity and plasticity so as to be collapsible and implantable remotely at a desired site. The wire mesh (1) is bent into three turns, two end ones (6, 6') and a central one (5), in such a way as to confine a tubular space. The central turn (5) is located at an angle relative to the end turns (6, 6') and mounts a monocusp sail-like valving element (2). A special catheter (12) is used to collapse the flexible wire mesh (1), to implant it remotely at the desired site, and to restore the wire mesh (1) to its original three-dimensional configuration.

The present invention relates to valves for use in living bodies.
More particularly, it relates to artificial valves for use in a blood vessel, internal to the blood vessel itself, in contact with the blood stream passing therethrough.
Still more particularly, though not exclusively, the present invention relates to valves which are intended to operate inside a vein with a monocusp valving element.
The present invention will be best understood on the basis of the following disclosure of its preferred embodiment, given only as a matter of example and not of restriction, with reference to the annexed drawings, wherein:
FIG. 1 is a side view of an artificial valve according to the present invention, in its closure position;
FIG. 2 is a front view of the same;
The support or valve body 1 is made up of a wire mesh 1, in a plastic material or in a biocompatible metallic alloy, such as the nickel (Ni) and cobalt (Co) alloy Phynox.RTM., eventually treated by antithrombogenic processes, having a circular cross section, with a diameter of about 0.3 millimeters, flexible, elastic and plastic, shaped and twisted so as to form three turns, of which there are two end ones 6, 6', substantially circular and lying on the periphery of the bases of a right cylinder, and a central one 5, with an ellipse-like contour substantially lying on a plane at about 130.degree. relative to said circle-like turns 6, 6'.
The so shaped valve body 1 gives the valve a cylinder cage configuration.
It is provided that the base of such a cylinder has a diameter of 6 to 14 millimeters and a height of 15 to 25 millimeters, the sizes being variable in connection with the veins whereinto the valve is to be positioned.
