    摘要： Techniques for forming cast parts for medical devices suitable for contact with internal regions of patients are described herein. Such parts can be small in scale (e.g., having a major axis less than 0.3 inches, and/or a minor axis less than about 0.08 inches), and can be formed from metals that have a high melting point and high reactivity with environmental components or mold surfaces, such as stainless steel and titanium alloys. Such techniques can include injecting molten metal into the sprue of a mold tree such that the side runners are backfilled after the molten metal impacts a closed end of the sprue. Side runners can be oriented in particular directions and positions to promote backfilling. As well, flask temperatures and the use of surfactants can also promote cast part formation, hindering the formation of surface defects.

    摘要： The present invention provides a surgical implant which can be made of a metal that corrodes while implanted in tissue. The implant can include an electrical insulator, such as in the form of a film, coating, or surface layer, for reducing the conductivity of the implant. The surgical implant can include a electrical insulator for reducing the conductivity of the implant. By way of example, the surgical implant can be in the form of a staple, and insulator can be in the form of an anodized surface layer.
