Declarations under Rule 4.17: - as to applicant's entitlement to apply for and be granted a patent (Rule 4. 17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4 . 17 (iii)) of inventorship (Rule 4.1 7(iv)) Published: — with international search report (Art. 21(3)) (54) Title: DEVICE FOR CARDIAC VALVE REPAIR AND METHOD OF IMPLANTING THE SAME (57) : The present invention relates to a device for cardiac valve re- 12 pair, the device comprising: at least one upstream anchoring means adapted to 10 anchor to at least one tissue site, the tissue site located upstream with respect 11 to a heart valve of a patient; and a coaptation structure arranged to extend from the upstream anchoring means, the coaptation structure comprising a free end, wherein the coaptation structure is operable to extend across the heart valve and locate the free end downstream from the heart valve and the coaptation structure operable to coapt with at least one heart valve leaflet of the patient's heart to prevent and/or minimize a backflow of blood. The present invention is suitable for the treatment of heart valves using minimally invasive approaches. Addi- tionally, the present invention is directed to a method of implanting a device for 12' cardiac valve repair in a patient's heart. Figure 5B
