We demonstrate that superconductors with broken inversion symmetry support afamily of stable, spatially localized configurations of the self-knottedmagnetic field. These solutions, that we term ``toroflux,'' are thesuperconducting counterparts of the Chandrasekhar-Kendall states (spheromaks)that appear in highly conducting, force-free astrophysical and nuclear-fusionplasmas. The superconducting torofluxes are solutions of superconductingmodels, in the presence of a parity-breaking Lifshitz invariant associated withthe $O$ point-group symmetry. These solutions are characterized by anon-vanishing helicity of the magnetic field, and also by a toroidal dipolemoment of the magnetic field. We demonstrate that a magnetic dipole or aferromagnetic inclusion in the bulk of a noncentrosymmetric superconductorsources finite-energy toroflux solutions.
