Abstract

Embodiments of a dynamically adjustable artificial chordae tendinae implant are described. In some embodiments the implant includes a body portion, including an adjustable portion. In some embodiments, the implant includes a plurality of adjustable portions. In some embodiments the adjustable element can include a shape memory material. The adjustable portion can be configured to transform from a first conformation to a second conformation in response to an activation energy. In some embodiments, the activation energy can be one of electromagnetic energy, acoustic energy, light energy, thermal energy, electrical energy, mechanical energy, or a combination of energies. The implant couples a heart valve leaflet to a papillary muscle. Activation of the shape memory material regulates tension between the muscle and valve leaflet improving coaptation of heart valve leaflets, and reducing or eliminating regurgitation.
