Abstract
A magnetic injection port assembly for a tissue expander system or similar inflatable medical device. The injection port assembly includes an injection port body having a cavity, a needle guard assembly, and a magnetic material therein. The needle guard assembly is positioned to prevent a hypodermic needle from passing through the medical device or interfering with the magnetic material. The magnetic material is affixed to the injection port body outside the cavity and the needle guard assembly. The magnetic material is spatially aligned with the region of the body into which the needle should be inserted so that this region may be located by locating the magnet with an external, non-invasive magnetic detection device.
