Docket #: S20-441

Epicardial and endocardial catheter system

Stanford researchers have developed a self-aligning two-sided (epicardial and endocardial) ablation system for treatment of atrial fibrillation (AF). Although several ablation systems for treatment of AF exist, this new two-sided system reliably achieves full transmural lesions, is easier and faster to use, and has a closed loop feedback system. This invention can potentially provide more effective treatment as compared to the systems used today.

Stage of Development

  • Proof-of-concept in open chest animals.
  • Continued work to finalize prototype and test in a closed chest animal
  • Applications

    • Arrhythmia/AF ablation

    Advantages

    • Full thickness ablation across the cardiac tissue
    • Perfect alignment of the epi and endo ablator catheters across the tissue where bipolar energy is delivered only across the tissue at the target
    • Automated, self-alignment due to series of magnets
    • Closed loop feedback system - series of ablation elements in communication with endo elements to adjust ablation intensity (time) depending on the tissue thickness
    • Reduced procedure time by ~80-90%
    • Simplified hardware by elimination of vacuum system
    • Optimized components
