Abstract
A subcutaneous delivery device assembly and method is provided. The assembly includes a subcutaneous delivery device comprising a catheter, a self-sealing input port at a first end of the catheter, an internal magnet adjacent to the self-sealing port and a valve at a second end of the catheter. The assembly further includes a corresponding external locator which is adapted to be magnetically located adjacent to the internal magnet and separator therefrom by a thin layer of human tissue. The assembly can be used to locate and stabilize a syringe needle during injection.
