Patents by Inventor Margaret D'Aversa

Margaret D'Aversa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6841083
    Abstract: A device for scouring a coating from a fibrous material includes a tank for immersing a plurality of fibers in scouring solvent therein. The device also includes a bubbling device positioned therein and having a chamber formed between a base plate and a cover plate with a plurality of holes. The plurality of fibers is mounted within the tank above the cover plate and holes of the bubbling device, so that gas bubbles produced thereby move through the scouring solvent and through the plurality of fibers. The holes are arranged in a pattern on the cover plate that corresponds to a shape assumed by the plurality of fibers when mounted within the tank. A process for scouring a coating from a fibrous material is also disclosed and involves immersing a plurality of fibers in a scouring solvent and producing a plurality of gas bubbles that move through the solvent and the plurality of fibers.

  • Patent number: 6712838
    Abstract: The present invention discloses a process for producing a braided suture having an improved knot strength comprising heating a braided suture coated with a low molecular weight biocompatible polymer to a temperature sufficient to melt the low molecular weight biocompatible polymer for a time sufficient to allow the low molecular polymer to be redistributed into the interstices of the braided suture thereby providing a coated braided suture with an improved knot tensile strength. Also disclosed is the coated braided suture having a low molecular weight polymer optimally dispersed throughout the braided suture's cross-section.
