Abstract:
A cannulation device for access to an interior body region comprisinga cannula body having a distal end for insertion through an incision and including first and second interior flow paths to circulate fluid, a conduit communicating with one of the first and second flow paths and extending beyond the distal end of the cannula body to input or outflow fluid at an area of the interior body region spaced from the distal end, a port communicating with the other one of the first and second flow paths to input or outflow fluid at the distal end, and a closure assembly on the cannula body operating in a first condition to close the port, thereby preventing fluid circulation within the cannula body between the first and second flow paths, the closure assembly operating in a second condition to open the port, thereby allowing fluid circulation within the cannula body between the first and second flow paths.
