Abstract
A minimally invasive system for monitoring and treating high intracranial pressure levels resulting from traumatic brain injury comprises an intravenous access device, an elongate member, a console, and an aspiration and injection catheter. The system is capable of monitoring pressure levels and relocating fluid from the brain to another part of the patient's body to sustain overall constant fluid volume. The method of using the minimally invasive system is also described.
Claims20
A system to stabilize intracranial pressure, comprising:
- an intravenous access device;
- an elongate member;
- and
- an aspiration and injection catheter having a first end, a second end, and a third end, the aspiration and injection catheter configured so that the first end and the second end can be positioned at least partially within a mammalian body, and further configured so that the third end can operably connect to a suction or injection device.
The system of claim, 4 wherein when the first valve is open and the second valve is closed, fluid within the aspiration and injection catheter may travel from the first end to the third end.
A method to stabilize intracranial pressure of a patient, comprising the steps of:
- placing a first end of an aspiration and injection catheter into a target site of a brain of a patient;
- placing a second end of the aspiration and injection catheter at a location in a vasculature of the patient and outside of a venous sinus of the brain of the patient;
- and
- placing a third end of the aspiration and injection catheter exterior to the patient;
- wherein the aspiration and injection catheter is configured to facilitate a flow of blood and from the brain of the patient, though the aspiration and injection catheter, and into to the vasculature of the patient.
A method to stabilize intracranial pressure of a patient, comprising the steps of:
- advancing an elongate member of a system to a target site of a brain of a patient, the system comprising:
- an intravenous access device,
- the elongate member, and
- an aspiration and injection catheter having a first end, a second end, and a third end, the aspiration and injection catheter configured so that the first end and the second end can be positioned at least partially within a mammalian body, and further configured so that the third end can operably connect to a suction or injection device;
- advancing at least part of the intravenous access device over at least part of the elongate member;
- and
- advancing the aspiration and injection catheter through the intravenous access device such that the first end is at the target site sinus of the brain of the patient, the second end is at a location in the vasculature of the patient and outside the venous sinus, and the third end is exterior of the patient.
