Abstract
A cannula system includes a main cannula, the main cannula providing blood exchange and a lumen isolated from the main cannula, the lumen providing a means for measuring pressure in an area of a human body.
Claims20
A cannula system, comprising:
- a main cannula, the main cannula providing blood exchange;
- a lumen isolated from the main cannula, the lumen providing a means for measuring pressure in an area of a human body.
A method of increasing life of organs of a patient, the method comprising:
- providing an improved cannula, the improved cannula including:
- a main cannula, the main cannula providing blood exchange;
- a lumen isolated from the main cannula, the lumen providing a means for measuring pressure in an area of a human body;
- using the main cannula to exchange blood near organs of the patient;
- monitoring the pressure in the area of the human body using the lumen, the human body belonging to the patient.
2 more elements
An improved cannula, the improved cannula comprising:
- a main cannula, the main cannula providing blood exchange;
- a lumen isolated from the main cannula, the lumen providing a means for measuring pressure in an area of a human body;
- wherein the main cannula includes a distal end, the distal end allowing for fluid to flow from the main cannula and the lumen includes an open end, the open end of the lumen set back from the distal end of the main cannula a distance effective for limiting an effect of fluid flow from the distal end of the main cannula on pressure sensed via the lumen.
