| abstract |
A device for reshaping a cardiac valve ( 26 ), which is elongate and has such dimensions as to be insertable into a cardiac vessel ( 24 ). The device has two states, in a first state (K) of which the device has a shape that is adaptable to the shape of the vessel ( 24 ), and to the second state (k′) of which the device is transferable from said first state (K). Further, the device comprises a fixing means ( 22,23;22 a, 23 a ) for fixing the ends of the device within the vessel ( 24 ), when the device is first positioned therein, a shape-changing member ( 20;20 a ) for transferring the device to the second state (K′) by reshaping it, and a delay means ( 21;21 a ) for delaying said reshaping until the fixing of the ends of the device has been reinforced by keeping said device in said first state (K) until the delay means ( 21;21 a ) is resorbed. |
