Apparatus for preventing dialysis graft intimal hyperplasia

摘要: To prevent intimal hyperplasia within a dialysis graft, flexible tube comprising the graft is coated interiorly with an anticarcinogen or mitosis-inhibiting agent for preventing cell division. The can also be irradiated by directing light into lumen of that has been grafted to patient's blood vessel. source emitting diode (LED) chemical source, i.e., chemiluminescent substance producing cool energy at site in sufficient amount undesired proliferation vessels, surrounding tissue where invention used without detectable damage body tissue. Visible used, e.g., visible blue red combination produced incandescent lamp other suitable lamp, LED, laser wavelengths predominantly between about 300 nm 800 nm.
