    摘要： The present disclosure relates to an arrangement, a loop-shaped support, a prosthetic heart valve and a method of repairing or replacing a native heart valve. With the method or the arrangement, leakage or regurgitation between a prosthetic heart valve and the surrounding valve tissue is prevented. In one embodiment, an arrangement for replacement or repair of a native heart valve is provided, which comprises a loop-shaped support (41) and a prosthetic heart valve (70) and wherein an outer segment (32) of the loop-shaped support (41) is positionable towards surrounding valve tissue of a native heart valve and wherein an outer surface (74) of the prosthetic heart valve (70) is positionable towards an inner segment (34) of the loop-shaped support (41) so as to prevent paravalvular leakage or regurgitation between the prosthetic heart valve (70) and the surrounding valve tissue of the native heart valve.

    摘要： A method for repairing a defective heart valve includes directing a delivery catheter to form a first curve around the heart valve at a first side of the heart valve leaflets and forming a second curve of the delivery catheter around the heart valve on a second side of the heart valve leaflets. The first and second curves are connected through a commissure of the heart valve and an annuloplasty implant is ejected from the delivery catheter while the delivery catheter is retracted such that the annuloplasty implant is arranged along the first and second curve.

    摘要： A medical arrangement for introducing an implant into an anatomical target position comprises a first introducer and a guide wire. The guide wire is configured to be introduced before the implant into or towards the anatomical target position. The implant is configured to be delivered along the guide wire into the anatomical target position. The guide wire is configured to be retracted after the implant has been introduced into said anatomical target position so that said object essentially maintains the shape taken when introduced into said anatomical target position.
