  "title": "Draining Brain Fluid into Neck Veins to Treat Hydrocephalus",
  "original_title": "Methods and systems for draining cerebrospinal fluid into the venous system",
  "summary": "This patent describes a medical device, a shunt, designed to drain excess fluid from the brain into a specific neck vein to treat a condition called hydrocephalus, using a controlled flow rate.",
  "what_it_does": "This patent describes a method for treating hydrocephalus by implanting a shunt in a patient's body. The shunt has openings at its far end to collect cerebrospinal fluid (CSF) from a specific area in the brain called the CP angle cistern. A tube, or lumen, carries this fluid to a valve located in the shunt's near end. The shunt is positioned so that its main body runs through the patient's Inferior Petrosal Sinus (IPS), and its near end is placed near the Jugular Vein (JV). After placement, the shunt allows CSF to flow from the brain's cistern into the Jugular Vein at a controlled rate, specifically between 5 ml and 15 ml per hour.",
  "what_it_does_not_cover": [
    "Does not cover shunts that drain cerebrospinal fluid into body cavities other than the venous system, such as the peritoneal cavity.",
    "Does not cover shunts where the distal portion is placed outside the CP angle cistern or the proximal portion is not near the Jugular Vein.",
    "Does not cover shunts that operate at a cerebrospinal fluid flow rate outside the specified range of 5 ml to 15 ml per hour.",
    "Does not cover methods for treating conditions other than hydrocephalus using this specific shunt configuration.",
    "Does not cover shunts that do not include a valve in their proximal portion for flow regulation."

  "abstract": "Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.",
