  • Publication number: 20260108745
    Abstract: A biostimulator includes a housing having a longitudinal axis and containing an electronics compartment. The biostimulator includes a fixation element coupled to the housing. The fixation element extends about the longitudinal axis. The biostimulator includes a pacing element coupled to the housing. The pacing element includes a flexible conductor extending along the longitudinal axis and a stiffening strand extending beside the flexible conductor. A bending stiffness of the stiffening strand is greater than a bending stiffness of the flexible conductor. Other embodiments are also described and claimed.

  • Publication number: 20250043235
    Abstract: The present invention provides polynucleotide vectors for high expression of heterologous genes. Some vectors further comprise novel transposons and transposases that further improve expression. Further disclosed are vectors that can be used in a gene transfer system for stably introducing nucleic acids into the DNA of a cell. The gene transfer systems can be used in methods, for example, gene expression, bioprocessing, gene therapy, insertional mutagenesis, or gene discovery.
