Abstract
An embodiment in accordance with the present invention provides an implanted catheter and an external device that the patient uses to inject a therapeutic into the implanted tube. The implanted catheter can be equipped with a fixation mechanism that secures the catheter in place and eases physician insertion and removal. The fixation mechanism can include shape memory arms having silicone tips or can be a second catheter branch configured to hold the device in the user's sinus cavity. The catheter can also include numerous exit holes to prevent obstruction and deliver the therapeutic. An interface between the implanted catheter and the external device is incorporated, to ensure a reliable seal for medication passage. A method and device for delivery of the catheter to the correct position can also be included.
