Implantable device as organ valve replacement
First Claim
1. Implantable device for use in a human and/or animal body for replacement of an organ valve, comprising:
- an expandable, elongate main body having a longitudinal axis and being substantially cylindrical in shape about said axis, said body including a first end and a second end each provided with an opening;
at least one outwardly protruding anchoring portion disposed proximate at least one of said first and second ends of said main body;
an expandable membrane element provided with at least one opening, said membrane element disposed within the main body and having a valve portion and a ring portion secured to the main body; and
said main body and said membrane element together movable between a first condition in which said main body and said membrane element together define a first cross sectional area, and a second, deployed condition in which said main body and said membrane element together define a second cross sectional area greater than said first cross sectional area.

Abstract
An implantable device for use in a human and/or animal body for replacement of an organ valve. The device has an elongate main body having a first end and a second end provided with openings, and a membrane element provided with at least one opening. The device has, in a first operating state (primary form), a large ratio of length to transverse extent along an axis, and, in a second operating state (secondary form), a smaller ratio of length to transverse extent along an axis. The device is reversibly convertible from the secondary form into the primary form by application of force against elastic material forces. At least one of the two ends of the main body has an outwardly protruding anchoring portion for anchoring the device in the organ and/or a vessel.

20. Implantable device for use in a human and/or animal body for replacement of an organ valve, comprising:
-
an elongate main body having a first end and a second end each provided with an opening; and a membrane element provided with at least one opening, said device having a deployed configuration having a relatively larger cross sectional area, and a non-deployed configuration having a relatively smaller cross sectional area, said device convertible from the non-deployed configuration to the deployed configuration by application of force against elastic material forces of the main body, wherein at least one of the first end and the second end of the main body has an outwardly protruding anchoring portion for anchoring the device in the organ and/or a vessel; wherein the main body is substantially of one piece; wherein the main body is cut and/or punched from a piece of material and/or separated therefrom by another method of separation; wherein the material section comprises parallel cuts and alternating subsequent cuts extending obliquely. - View Dependent Claims (21, 22, 24)
