Device for heart repair

Disclosed herein is a catheter device (2) for implanting a leaflet anchor (10) and a papillary anchor (9) into the heart as part of a procedure for implanting an artificial chordae line (14) that extends between the leaflet anchor (10) and the papillary anchor (9), the catheter device (2) comprising: a two-part housing section extending from a distal end (8) of the catheter device (2) along the length of the catheter device (2) toward the proximal end (4) of the catheter device (2), the two-part housing section being arranged to be placed between the papillary muscle and a leaflet (12) of the heart during use of the catheter device (2), and the two-part housing section comprising a distal part (8) at the distal end of the catheter device (2) and a proximal part (4) located on the proximal side of the distal part (8); a leaflet anchor deployment mechanism at the proximal part (4) of the housing section for deploying a leaflet anchor (10) for attachment to the leaflet (12) of the heart; a papillary anchor deployment mechanism at the distal part (8) of the housing section for deployment of a papillary anchor (9) for attachment to the papillary muscle, wherein the papillary anchor deployment mechanism is arranged for deployment of the papillary anchor (9) by moving it outward in the distal direction relative to the distal part (4); and a flexible joint (34) located between the proximal part (4) and the distal part (8) of the two-part housing section, wherein the flexible joint (34) allows a centreline of the distal part (8) to be angled relative to a centreline of the proximal part (4).
