ENDOCISTERNAL KIT AND METHOD FOR CREATION OF A CEREBRAL THIRD FLOOR VENTRICULOSTOMY USING MINIMALLY INVASIVE TECHNIQUES

Abstract: a method of performing a ventriculostomy includes creating an access site in a lumbar region. a guidewire is inserted into the access site. a sheath is introduced over the guidewire, into the access site, and the tip of the sheath is positioned in a subarachnoid space. a first catheter and a second catheter are introduced through the access site. the first catheter and the second catheter are guided proximate to a ventricle membrane of a ventricle. a hole is created in the ventricle membrane and at least one of the first catheter or the second catheter are advanced through the hole. the hole in the ventricle membrane is dilated. contrast is injected into the ventricle to confirm cerebrospinal fluid is draining into a subarachnoid cistern.
