  • Patent number: 10722221
    Abstract: The present invention utilizes tetherless microtools to biopsy tissue. The invention provides a device and method for deployment and retrieval of tetherless microtools. The size of the microtools ensures that tissue damage at a site targeted for biopsy is negligible. As such, large numbers of microtools may be deployed ensuring that a true statistical sampling of biologic tissue is performed.

  • Publication number: 20200197535
    Abstract: The present invention relates to the field of extracellular vesicles. More specifically, the present invention provides methods and compositions for using extracellular vesicles as a vector for nucleic acid treatment in vivo of various diseases. In a specific embodiment, the present invention provides an extracellular vesicle isolated from a cell comprising one or more microRNAs (miRNAs) that have been loaded ex vivo into the vesicle so that the miRNAs are present in a higher concentration than when measured in the same extracellular vesicle isolated directly from the cell. In another embodiment, the present invention provides a method for treating cholangiocarcinoma in a subject comprising the step of administering to the subject a plurality of exosomes comprising miR-195.

  • Patent number: 10441760
    Abstract: The presently disclosed delivery systems utilize microtools, also referred to as theragrippers, to deliver a drug or other therapeutic agent to targeted tissue. More particularly, the drug delivery system and methods provide a delivery system that is capable of anchoring to a tissue site and then delivering a drug or therapeutic agent to the tissue directly to or in the vicinity of the site over an extended period of time. Any number of theragrippers may be deployed as desired to deliver different doses of a desired drug or therapeutic agent. The theragrippers also can be biodegradable such that they remain in place for an extended period of time and then degrade without adversely affecting the surrounding tissue.
