Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, comprising: a bent flexible wire having elasticity and plasticity so as to be resilient, self-expanding and implantable remotely at a desired site; wherein said wire is bent into at least three turns, to confine a tubular space, said at least three turns including a central turn and two end turns, said central turn being at an angle relative to said end turns; and a monocusp valving element mounted on the central turn.
Claim 2
Dependent Claim
92 words
A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, comprising: a bent flexible wire having elasticity and plasticity so as to be resilient, self-expanding and implantable remotely at a desired site; wherein said wire is bent into at least three turns, to confine a tubular space, said at least three turns including a central turn and two end turns, said central turn being at an angle relative to said end turns; and a monocusp valving element mounted on the central turn.
Claim 3
Dependent Claim
19 words
The valve according to claim 1, wherein the valving element has a check line fixed to said central turn.
Claim 4
Dependent Claim
103 words
A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, comprising: a bent flexible wire having elasticity and plasticity so as to be resilient, self-expanding and implantable remotely at a desired site; wherein said wire is bent into at least three turns, to confine a tubular space, said at least three turns including a central turn and two end turns, said central turn being at an angle relative to said end turns; a monocusp valving element mounted on the central turn; and hooking means for fixing the wire to a blood vessel wall.
Claim 5
Dependent Claim
103 words
A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, comprising: a bent flexible wire having elasticity and plasticity so as to be resilient, self-expanding and implantable remotely at a desired site; wherein said wire is bent into at least three turns, to confine a tubular space, said at least three turns including a central turn and two end turns, said central turn being at an angle relative to said end turns; a monocusp valving element mounted on the central turn; and hooking means for fixing the wire to a blood vessel wall.
Claim 6
Dependent Claim
113 words
A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, comprising: a bent flexible wire having elasticity and plasticity so as to be resilient, self-expanding and implantable remotely at a desired site; wherein said wire is bent into at least three turns, to confine a tubular space, said at least three turns including a central turn and two end turns, said central turn being at an angle relative to said end turns; a monocusp valving element mounted on the central turn; and means for preventing the valving element from stopping in an arbitrary position other than the desired site in the blood vessel.
Claim 7
Dependent Claim
113 words
A valve for use in a blood vessel, internal to the blood vessel itself, in contact with a blood stream, comprising: a bent flexible wire having elasticity and plasticity so as to be resilient, self-expanding and implantable remotely at a desired site; wherein said wire is bent into at least three turns, to confine a tubular space, said at least three turns including a central turn and two end turns, said central turn being at an angle relative to said end turns; a monocusp valving element mounted on the central turn; and means for preventing the valving element from stopping in an arbitrary position other than the desired site in the blood vessel.
Claim 8
Dependent Claim
19 words
The valve according to claim 4, wherein the preventing means comprises a check line anchored to said central turn.
Claim 9
Dependent Claim
76 words
A catheter comprising: means for folding a valve body (1) from an original three-dimensional configuration into a temporary and linear form, a capsule means (13) for transporting the valve body (1) into a blood vessel, means (19 to 25) for grasping and loading the valve body (1), into said capsule means (13), means for releasing the valve body (1) at a desired site, and means for restoring the valve body (1) to the original three-dimensional configuration.
Claim 10
Dependent Claim
76 words
A catheter comprising: means for folding a valve body (1) from an original three-dimensional configuration into a temporary and linear form, a capsule means (13) for transporting the valve body (1) into a blood vessel, means (19 to 25) for grasping and loading the valve body (1), into said capsule means (13), means for releasing the valve body (1) at a desired site, and means for restoring the valve body (1) to the original three-dimensional configuration.
Claim 11
Dependent Claim
20 words
The catheter according to claim 6, further comprising: an inflatable balloon (14) to obtain the occlusion of a blood vessel.
