A catheter (4) based medical system (1) and medical procedure for reducing cardiac valve regurgitation are disclosed. The system comprises a resilient curvilinear shaped annuloplasty implant (3) for reducing the size of a dilated annulus (18) of said valve for reducing said regurgitation having resilient anchoring elements (300), and a delivery device (2) for said annuloplasty implant (3) having a distal curvilinear shaped portion (200) that is hollow to mount said annuloplasty implant (3) and has an annular opening (201) arranged to be in apposition against an annulus (18) of said cardiac valve. A plurality of suction units allows for a atrial approach and symmetric implantation of said implant.
