Medtronic 42314 CSF-Flow Control Valve Contoured Small-Medium Pressure
Part # 42314 Exp 2/15
The Medtronic 42314 CSF-Flow Control Valve is a pressure differential valve built to open at a set pressure. In vivo, the pressure that the valve responds to is the difference between the intracranial pressure and the pressure of the space into which the distal end of the system is draining into (e.g., the intraperitoneal pressure).
In Perfect sealed condition but past expiration date. Not for human use in the US.
Expiration dates have mostly to do with sterilization and not the integrity of the product. The manufacturers sterilize the products after they are packaged and it lasts so many years. The only products we caution customers about are ones that are absorbable or drug coated.
