  "title": "Removing Blood Clots from Brain Vessels with a Special Catheter",
  "original_title": "Rapid aspiration thrombectomy system and method",
  "summary": "This patent describes a specialized catheter system designed to quickly remove blood clots from tiny blood vessels in the brain, often used to treat strokes, by using suction.",
  "what_it_does": "The patent describes an intravascular access system for medical procedures inside the brain's blood vessels, specifically for rapid aspiration thrombectomy. The system includes an aspiration or support catheter with a flexible, hollow tip (distal luminal portion) that has an inner diameter defining a lumen. This lumen extends from a proximal opening to a distal opening. A key feature is a rigid spine attached to at least the proximal end of this flexible tip, extending backward. The system also includes a dilator, which is a flexible, thin device designed to fit inside the catheter's hollow tip. This setup allows doctors to navigate delicate brain blood vessels, reach a clot, and remove it using aspiration, which means sucking it out.",
  "what_it_does_not_cover": [
    "Does not cover systems for removing clots from blood vessels outside the brain (e.g., in the heart or legs).",
    "Does not cover systems that use mechanical retrieval methods, like tiny cages or nets, instead of aspiration (suction).",
    "Does not cover catheter systems where the rigid spine is not coupled to the proximal end of the flexible luminal portion.",
    "Does not cover systems that lack a separate dilator component designed to be received within the catheter's lumen.",
    "Does not cover catheters where the distal luminal portion is not flexible.",
    "Does not cover systems where the rigid spine does not extend proximally from the luminal portion."

  "abstract": "An intravascular access system for facilitation of intraluminal medical procedures within the neurovasculature through an access sheath. The system includes an aspiration or support catheter having a flexible, distal luminal portion having an inner diameter defining a lumen extending between a proximal opening at a proximal end of the luminal portion and a distal opening at a distal end of the luminal portion. The catheter has a rigid spine coupled to at least the proximal end of the luminal portion and extending proximally therefrom. The system includes a dilator having a flexible, distal dilator portion sized to be received within the lumen of the luminal portion. Associated systems, devices, and methods of use are also described.",
