Patent 12083299 was granted and assigned to NXT BIOMEDICAL LLC on September, 2024 by the United States Patent and Trademark Office.
A shunt is described that expands to an hourglass shape. As the shunt expands, both of its ends radially flare outwards relative to its middle section and the length of the shunt foreshortens, which causes the flared ends to engage the tissue surrounding a puncture or aperture within a patient's tissue.
