Abstract
A dual port vascular access assembly comprises a first access port and a second access port. The linkage is coupled between the first access port to close the second access port in the absence of an access tube in the first access port. Such port assemblies are particularly useful for implantation in patients receiving hemodialysis. By connecting the first access port to the blood withdrawal side of the system, blood withdrawal will be automatically terminated upon cessation of blood returned to due loss of the return access tube in the port assembly.
