Tissue Expander with Means to Deliver Antibiotics or Medication Uniformly on its Surface Using Multiple Channels Comprising Pores

摘要

A tissue expander distributes antibiotics or other drugs and treats infections to the surrounding tissue. The tissue expander is provided with a manifold that can be accessed from outside via an injection needle which is connected to a series of channels containing drug effusion ports. When the tissue is infected antibiotics are injected into the manifold which in turn runs through the channels, effuse out the strategically placed ports to treat the infection. The procedure can be repeated until the infection is resolved. Any fluids effusing from the tissue are drained using the drainage channels that connect to a central drainage cavity and is later drained out of the body using a needle or cannula placed into a special drainage collection cavity.
