Patents by Inventor Eric Kendall

Eric Kendall 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: 11772099
    Abstract: The present invention relates to a microfluidic system including a temperature controller and a thermoplastic microfluidic chip that enables rapid PCR in a PCR chamber of the microfluidic chip. Thermal control of the PCR chamber is achieved by applying voltage to heater electrodes patterned directly onto one layer of the microfluidic chip. The temperature controller adjusts the voltage applied to the heater electrodes by changing temperature controller parameters selected to minimize duration of each PCR cycle. Furthermore, simple operation of the microfluidic chip is provided through using an integrated passive capillary valve, requiring minimum operator intervention and eliminating the need for fluidic interfacing, pumping, or metering during chip loading.

  • Publication number: 20210156842
    Abstract: A centrifugal cartridge or disk used for extraction of light supernatant fractions from fluid samples is described, particularly for non-homogenous fluid biological samples such as whole blood. The device may be used to collect cell-free blood plasma or a fraction of whole blood containing target cells such as leukocytes. Single or multiple channels are described, including channels with passive valves, gaskets, receiving cavities, inlet holes, capillary wicking ridges, distal cavities for cell retention, separator gel, and density medium. Centrifugal action causes whole blood in a receiving cavity to pass into one or more channels where it separates into blood cells, plasma and optionally fractions of an intermediate density. After spin, the plasma returns to the receiving cavity by way of the one or more channels for extraction through the inlet hole or other inwardly located hole.

  • Publication number: 20140328898
    Abstract: A method for transdermal drug delivery provides for the topical administration of liposome encapsulated nanoparticles. The encapsulated nanoparticles define a nearly monodisperse population of liposomes having an average diameter within a selected size range. Liposomal nanoparticle formulations and methods of treatment therewith are also provided.
