Device for Closure of Transvascular or Transcameral Access Ports

This technology includes a novel method to access the arterial circulation to allow introduction of large devices, such as transcatheter aortic valve replacement, percutaneous left ventricular assist devices, and thoracic aortic endografts. It also can be used in most labeled and off-label applications of Amplatzer nitinol occluder devices to occlude intracardiac holes and to allow non-surgical direct access to the heart. This new disclosure adds additional design features that have been tested in vivo. These include a new compression member design that enhances wall apposition and hemostasis, a new delivery cable design, alternative endoluminal limb designs. The new design allows flexible deliver and recovery but is designed to avoid inadvertent pull-through. The disclosed invention has already been built and reduced to practice in an animal model.
