Overall, the company, based in Eden Prairie, Minnesota, is seeking $1 million, the documents say.
In September 2010, the U.S. Patent and Trademark Office awarded Nascent executive Dr. Leonard Schultz a patent for a device that can more easily filter and remove smoke during surgical procedures involving lasers, including laparoscopies- operations that require small incisions in the abdomen or pelvis.
“An advantage of the present invention is that it eliminates dependency on a built-in, in wall vacuum source,” the patent says. “It does not require high vacuum suction and the requisite high resistance filters or combination of flow restrictors or reducers and filters. Further, it simplifies smoke evacuation and filtering by eliminating the need for multiple, in-line structures (filters, resistors, etc.) for stepping down or reducing suction.”
