Abstract
A catheter device is described. The device is for implanting an artificial chordae line () in the heart. The catheter device comprises: a leaflet anchor () for placement in a leaflet () of a heart valve, wherein the leaflet anchor () is arranged to be coupled to the artificial chordae line (); and a leaflet anchor deployment mechanism () for deploying the leaflet anchor (), wherein the leaflet anchor deployment mechanism () comprises a mechanical gripper device ('), for grasping the leaflet (), wherein the gripper device (′) comprises a leaflet anchor tubefor housing the leaflet anchor () in a folded configuration. The gripper device () and the leaflet anchor () are arranged such that when, in use, the gripper device () grasps the leaflet (), the leaflet anchor () can be pushed out of the leaflet anchor tube () to pierce the leaflet () and form the leaflet anchor () into an unfolded configuration so that hooked formations of the leaflet anchor () can, in use, secure the leaflet anchor () in the leaflet (). The mechanical gripper device () includes a first gripper arm () rotatably coupled to a main body () of the catheter device so that the gripper arm () can rotate relative to the catheter device to move an outer end () of the first gripper arm () away from the main body () of the catheter device and a second gripper arm (′) rotatably and/or slideably coupled to the main body () of the catheter device so that the second gripper arm (′) can rotate and/or slide relative to the main body () of the catheter device to move an outer endof the second gripper arm (′) away from the main body (). The first and second gripper arms (′) are arranged so that they can move to come into contact with one another at a point spaced apart from the main body () of the catheter device.
