MODEL RELEASED. Catheter from an implanted venous access port (portacath) under the skin of a patient with haemophilia. The port (not seen) has a septum through which drugs can be injected and blood samples can be drawn many times. The catheter connects the port to a vein. This method of administration is used to deliver drugs and fluids in certain patients, in this case coagulation factors to treat haemophilia. Such ports are sometimes used to deliver chemotherapy, and for lengthy or frequent delivery of antibiotics in some patients, such as those with cystic fibrosis.
