A medical arrangement configured to introduce an annuloplasty device from a distal end of the arrangement into an anatomical target position, the medical arrangement comprising - a first introducer having distal and proximal ends (101A, 101B), and - a second introducer having distal and proximal ends (102A, 102B), wherein - said first introducer is an outer introducer, and said second introducer is configured to be operated inside and guided by said first introducer, and - at least a portion of the first introducer is configured to take a first curved shape, and at least a portion of the second introducer is configured to take a second curved shape, wherein said first and second curved shapes (101C, 102C) are concentric curved shapes (101C, 102C), characterised in that - said first introducer is configured to take said first curved shape when said first introducer is delivered towards or into said anatomical target position, said second introducer is configured to take said second curved shape to the same hand direction as the first curved shape of the first introducer when said second introducer is introduced from the distal end portion of the first introducer, - said anatomical target position is a left atrium or left ventricle or an annulus area of a mitral valve, whereupon said first introducer is configured to be delivered into a first side of the annulus of the mitral valve essentially in a mitral plane on in an angle less than 45° and more advantageously less than 30° in relation to the mitral plane, and - said portion of the first and second introducer (101, 102) taking said curved shape (101C, 102C) is also configured to form an angle (109A, 109B) in a direction essentially perpendicular to the mitral plane, wherein the second introducer is configured to be delivered between leaflets (22, 24) to the second side of the annulus of the mitral valve said second side of the annulus being opposite to said first side. - a first introducer having distal and proximal ends (101A, 101B), and - a second introducer having distal and proximal ends (102A, 102B), wherein - said first introducer is an outer introducer, and said second introducer is configured to be operated inside and guided by said first introducer, and - at least a portion of the first introducer is configured to take a first curved shape, and at least a portion of the second introducer is configured to take a second curved shape, wherein said first and second curved shapes (101C, 102C) are concentric curved shapes (101C, 102C), - said first introducer is configured to take said first curved shape when said first introducer is delivered towards or into said anatomical target position, said second introducer is configured to take said second curved shape to the same hand direction as the first curved shape of the first introducer when said second introducer is introduced from the distal end portion of the first introducer, - said anatomical target position is a left atrium or left ventricle or an annulus area of a mitral valve, whereupon said first introducer is configured to be delivered into a first side of the annulus of the mitral valve essentially in a mitral plane on in an angle less than 45° and more advantageously less than 30° in relation to the mitral plane, and - said portion of the first and second introducer (101, 102) taking said curved shape (101C, 102C) is also configured to form an angle (109A, 109B) in a direction essentially perpendicular to the mitral plane, wherein the second introducer is configured to be delivered between leaflets (22, 24) to the second side of the annulus of the mitral valve said second side of the annulus being opposite to said first side.
