Abstract
The present disclosure relates generally to the field of medical devices for clamping a leaflet of a heart valve. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. In an embodiment, a system may include a clamp having a plurality of arms at a first end. The plurality of arms may have a closed configuration in which the arms are oriented toward each other, and an open configuration in which the arms are oriented away from each other. A spring portion may be coupled to the plurality of arms at a second end that is configured to bias the arms to the closed configuration. The arms of the clamp may be configured to fixedly engage with a leaflet of the heart valve. The second end of the clamp may be configured to couple to an artificial chordae tendineae.
