April 23, 2026—Omnia Inventa Medical has introduced the Lymph Node Locator 300, an FDA class I, 510(k)-exempt device designed to standardize lymph node retrieval from fatty tissue in oncologic specimens. The LNL300 applies the acetone compression method to remove fat and convert mesenteric tissue into a compact, uniform stromal block. The block can then be directly sectioned into standard cassettes, enabling systematic histological examination of the entire relevant tissue matrix. The benchtop device aims to ensure a consistent and reproducible workflow that is independent of operator variability.
“Pathology workflows have long relied on individual technique,” Oleg Ratner, MD, PhD, CEO of Omnia Inventa Medical, said in a press release. “The LNL300 provides a simple and practical way to achieve consistency in lymph node retrieval.”
The device does not require consumables, maintenance, or specialized infrastructure.
