Abstract: Rapid prototyping and delivery of fluorescent medical devices using a 3D printer provided with a processed digital design and fluorescent filament feedstock. The fluorescent filament may comprise a polymer such as acrylonitrile butadiene styrene and between 10 and 100 ppm of a fluorophore such as indocyanine green embedded uniformly throughout the polymer. The filament may include about one percent by weight of a colorant. The 3D printer may be located at the site of use by an end user, such as a physician office, hospital, or operating room for printing of the fluorescent medical device on demand.

Abstract: A biopsy marker that can emit near infrared fluorescence for location of a biopsy site. The biopsy marker has a body formed from a polymer and a quantity of a near infrared fluorescent dye, such as indocyanine green, embedded in the polymer. A near infrared energy source is used to excite the near infrared fluorescent dye. A near infrared energy detector is used to detect any near infrared emissions from the biopsy marker. As a result, any and all biopsy markers within the field of view may be readily identified and located so that the tissue locations can be surgical removed if the tissue samples indicate a risk of cancerous tissue.
