Joseph Willis 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).

  • Publication number: 20260092329
    Abstract: The disclosure provides methods for identifying genomic loci (e.g., vimentin and/or SqBE18) that are differentially methylated in metaplasias (e.g., Barrett's esophagus) and/or neoplastic cancers (e.g., esophageal cancers). Identification of methylated genomic loci has numerous uses, including for example, to characterize disease risk, to predict responsiveness to therapy, to non-invasively diagnose subjects and to treat subjects determined to have gastrointestinal metaplasias and/or neoplasias.

  • Publication number: 20260069257
    Abstract: A device for collecting a biological sample in a patient includes a collection portion having a first axial end portion and a second axial end portion. The second axial end portion has a collapsed position and an expanded position. The second axial end portion moves in an axial direction relative to the first axial end portion when the second axial end portion moves between the collapsed position and the expanded position. The second axial end portion extends axially into the first axial end portion and has a concave shape when in the collapsed position. The second axial end portion is convex when in the expanded position.

  • Publication number: 20210369256
    Abstract: A method for collecting a cell sample, including eosinophil white blood cells in a patient is provided. The method includes advancing to a location in an esophagus associated with eosinophilic esophagitis (EoE), a device provided with a collection portion having a first axial end portion and an inflatable second axial end portion. Thereafter, axially moving the second axial end portion, relative to the first axial end portion, from a collapsed position within the first axial end portion into an expanded position out from the first axial end portion. Once the second axial end portion is in the expanded position, allowing it to engage the location associated with EoE to collect a sample of cells.
