Patents by Inventor Stephen W. Chandler

Stephen W. Chandler 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: 11058855
    Abstract: Methods and devices quickly and accurately locate the sphenopalatine ganglion (SPG) while performing a sphenopalatine ganglion block procedure that introduces a medication to the SPG. The methods and devices also prevent the medication applied to the SPG from flowing down a patient's throat during the procedure.

  • Publication number: 20200246599
    Abstract: A device, a system and a method are provided to accurately apply a medically beneficial substance directly to a laterally or superiorly located paranasal sinus cavity. When the device is assembled with a solution in a reservoir, and inverted such that the reservoir is above an input apparatus and a housing, weight of the solution pushes down on a diaphragm creating a negative pressure on the diaphragm, which prevents air from entering the reservoir and prevents a liquid from flowing out of the reservoir. Applying a positive pressure to a bottom of the diaphragm causes the diaphragm to open and allows air to flow into the reservoir. When a user creates the positive pressure by exhaling air into the device the act of exhaling causes the user's choana to close. Thereby any solution introduced into the user's sino-nasal cavity will remain contained within the user's sino-nasal cavity increasing effectiveness of treatment and decreasing user discomfort including gagging, choking, and inner ear disturbance.

  • Patent number: 10589072
    Abstract: Methods and devices to quickly and accurately apply medication to a paranasal sinus are disclosed. Additionally, the methods and devices prevent the medication applied to a paranasal sinus from flowing down a patient's throat by expanding, using an inflation lumen of a device, an expandable member of the device adjacent to the patient's choana.
