  • Patent number: 5868746
    Abstract: A biocompatible osteosynthesis plate operable for being enhanced in a substantially secured relation to a plurality of adjacent bone portions is provided. The biocompatible osteosynthesis plate includes an elongated section having a top face and a bottom face, at least one fastener opening disposed between the top face and the bottom face, and means disposed upon elongated section to permit the formation of additional fastener openings therethrough during a surgical procedure. The osteosynthesis plate is in a first configuration at a first thermochemical state and is operable to be converted to a second thermochemical state so that it may be deformed prior to fixation. The osteosynthesis plate may further include means disposed upon the elongated section for enhancing structural rigidity, which may be provided as one or more raised surfaces, or rails, disposed upon the top face of the osteosynthesis plate.

  • Patent number: 5702656
    Abstract: Processes for fabricating substantially void-free polymeric articles are provided. In one embodiment, a polymer melt is formed followed by extrusion through a die to form a polymeric extrudate. The polymeric extrudate is directly discharged vertically upward into an open-ended mold the open-ended mold having a longitudinal axis oriented substantially vertically. The polymeric article is cooled and removed from the mold. In a further embodiment, a mold is loaded with polymeric particles. The mold is oriented such that its longitudinal axis is substantially vertical. A vacuum is drawn on the loaded mold followed by heating the loaded mold above the melting point of the polymeric particles. After the polymeric particles are melted, the loaded mold is charged with an inert gas to above ambient pressure to collapse any remaining voids. The loaded mold is slowly cooled to form a polymeric article. Oriented polymeric bioabsorbable cannulated surgical articles and a method of making same are provided.
