    摘要： The present disclosure relates generally to the field of medical devices for delivering artificial chordae tendineae in a patient An anchor for engaging a papillary muscle or heart wall is described, wherein the anchor is movable between a delivery configuration and a deployed configuration. When the anchor is in the delivery configuration the anchor has a first outer dimension and when the anchor is in the deployed configuration the anchor has a second outer dimension. The first outer dimension is smaller than the second outer dimension. The anchor is engageable with a papillary muscle or a heart wall when the anchor is in the deployed configuration. The anchor comprises a plurality of arms coupled at a proximal end thereof to a body portion, at least one arm of the plurality of arms movable between a first position and a second position when the anchor moves from the delivery configuration to the deployed configuration. The plurality of arms each have a distal tip for engaging the papillary muscle or heart wall, wherein as the anchor is moved from the delivery configuration to the deployed configuration, the plurality of arms are movable from an elongated shape to a curved shape.
