Artificial valve for implantation and related methods
First Claim
1. An artificial valve for implantation in a patient'"'"'s blood vessel comprising:
- a first valve member of the artificial valve,a second valve member of the artificial valve,each of the first and second valve members having a first smooth surface on a first side of the respective valve member and a second surface on a second side of the respective valve member, opposite the first side of the respective valve member,the first smooth surface of the first valve member facing the first smooth surface of the second valve member so as to form a sealing contact between the first and second valve members,each of the first and second valve members further having at least one blood flow passage extending from the first surface of the respective valve member, completely through the respective valve member to the second surface of the respective valve member,at least one of the first and second valve members being arranged so as to be displaceable relative to the other valve member in a slidable manner, such that the blood flow passage of the second valve member can be brought into at least partial alignment with the blood flow passage of the first valve member while maintaining the sealing contact between the first and second valve members, anda displacing mechanism of the artificial valve for the displacement of the first and second valve members relative to one another, the displaceable arrangement of the first and second valve members relative to one another being such that the at least one displaceably arranged valve members is continuously slidable in one direction.

Abstract
An artificial valve (100) and related methods are provided for implantation in a patient'"'"'s blood vessel (200), in particular an artificial heart valve, including a first (10) and a second (20) valve member each having a first smooth surface (11, 21) facing each other so as to form a sealing contact between the first and second valve members and further having at least one blood flow passage (13, 23a) extending from the first surface to a second surface (12, 22) located on an opposite side of the respective valve member, wherein at least one (10) of the valve members is arranged so as to be displaceable relative to the other (20) valve member in a slidable manner such that the passage (23a) of the second valve (20) member can be brought into at least partial alignment with the passage (13) of the first valve member (10) while maintaining the sealing contact between the first and second valve members, and a displacing mechanism (M; 50-56) for the relative displacement of the valve members (10, 20). The valve members can be made from ceramics. A valve system comprises the artificial valve (100) and additional components such as a motor (M), an energy source (E), a control unit (C), a pressure sensor (P), a feed back system and/or an alarm system.

68. A valve system comprising an artificial valve for implantation in a patient'"'"'s blood vessel comprising:
-
a first valve member of the artificial valve, a second valve member of the artificial valve, each of the first and second valve members having a first smooth surface on a first side of the respective valve member and a second surface on a second side of the respective valve member, opposite the first side of the respective valve member, the first smooth surfaces of the first and a second valve members facing each other so as to form a sealing contact between the first and second valve members, the first and second valve members further having at least one blood flow passage extending completely through the respective valve member from the first surface of the respective valve member to the second surface of the respective valve member, at least one of the valve members being arranged so as to be displaceable relative to the other valve member in a slidable manner such that the blood flow passage of the second valve member can be brought into at least partial alignment with the blood flow passage of the first valve member while maintaining the sealing contact between the first and second valve members, and a displacing mechanism of the artificial valve for the relative displacement of the first and second valve members, the displacing mechanism comprising a motor for displacing the at least one displaceably arranged valve member continuously in one direction and thereby bringing the blood flow passages of the first and second valve members into and out of alignment, and an energy source for providing the motor with energy from outside the blood vessel. - View Dependent Claims (69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89)
