Abstract
The implant implantation unit (2), at a determined position in the tubular element (51) with a wall comprising a cavity (50), is pushed there by a catheter (60) and the unit comprises deformable feelers (31) to, under the control of remote activation elements (42), change from a stowed form to a deployed functional form, to detect the cavity (50) and position itself there with reference to the position of the cavity.

11. A method comprising:
-
providing a semilunar valve prosthesis; placing the prosthesis in a body of a subject; and determining a correct rotational disposition of the prosthesis with respect to a semilunar valve site based on tactile feedback. - View Dependent Claims (12, 13)

14. A method comprising:
-
placing a semilunar valve prosthesis at a native semilunar valve site; and causing the prosthesis to self-align with respect to the site by gently rotating the valve prosthesis. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method, comprising:
-
placing a semilunar valve prosthesis at a native semilunar valve site, the prosthesis shaped so as to define one or more proximal engagement arms; attempting to position the engagement arms at least partially within respective semilunar sinuses of the native semilunar valve site; and verifying that the engagement arms are properly placed with respect to the semilunar valve site by attempting to rotate the engagement arms with respect to the semilunar valve site. - View Dependent Claims (25)

26. Apparatus comprising a prosthesis for implantation at a native semilunar valve of a native valve complex of a subject, the prosthesis comprising a support structure, which is configured such that a correct rotational disposition of the prosthesis with respect to the native semilunar valve can be determined based on tactile feedback.

27. Apparatus comprising a prosthesis for implantation at a native semilunar valve of a native valve complex of a subject, the native valve complex having three semilunar sinuses and three native commissures, the prosthesis comprising a valve prosthesis support, which comprises a support structure comprising exactly three engagement arms that meet one another at three respective junctures,
wherein the engagement arms are shaped so as to define three peak complexes at the three respective junctures, and three trough complexes, each of which is between two of the peak complexes, and wherein, upon implantation of the prosthesis, each of the engagement arms is at least partially disposed within a respective one of the semilunar sinuses, such that each of the peak complexes is disposed distal to a respective one of the native commissures, and each of the trough complexes is disposed at least partially within the respective one of the semilunar sinuses.

43. A method for implanting a prosthesis at a native semilunar valve of a native valve complex of a subject, the native valve complex having three semilunar sinuses and three native commissures, the method comprising:
-
providing the prosthesis including a valve prosthesis support, which valve prosthesis support includes a support structure comprising exactly three engagement arms that meet one another at three respective junctures, wherein the engagement arms are shaped so as to define three peak complexes at the three respective junctures, and three trough complexes, each of which is between two of the peak complexes; and implanting the prosthesis such that each of the engagement arms is at least partially disposed within a respective one of the semilunar sinuses, each of the peak complexes is disposed distal to a respective one of the native commissures, and each of the trough complexes is disposed at least partially within the respective one of the semilunar sinuses.
