The SignalMark Lung Biopsy Site Marker is intended to provide accuracy in marking a biopsy location for visualization during surgical resection.

The SignalMark Lung Biopsy Site Marker is a medical device used by a physician to percutaneously place a small implantable hydrogel marker in lung tissue biopsy to "mark" the location of the biopsy site. It is intended to be used on adults undergoing percutaneous lung biopsies, in surgical settings, such as hospitals or medical clinics with operating suites. The SignalMark Lung Biopsy Site Marker consists of two components: - Applicator: Component made of plastic and stainless steel that pushes the marker into the tissue. - Marker: Component made of USP-grade porcine gelatin-based hydrogel with methylene blue-colored silicon dioxide microspheres. The marker aids in the visualization of tissue allowing surgeons to readily locate the biopsy site for subsequent tissue or tumor resection.
