ABSTRACT:
A medication infusion pump is provided of the type adapted for implantation into the body of a patient, and for programmable delivery of a selected medication through a catheter to the patient over an extended period of time. A side port assembly is mounted quickly and easily onto the pump and defines a flow path through which the medication is discharged to the catheter. The side port assembly includes an access port to permit transcutaneous needle access to the discharge flow path, in combination with a check valve to prevent backflow within the discharge flow path. The discharge side access port can be used to flush residue from the catheter, or in combination with a primary refill port on the pump to flush the pump and/or to determine actual pump stroke volume.
