No
The device description and intended use focus on a radioactive seed and needle for lesion localization, with no mention of AI or ML capabilities. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
No.
The device is used for marking and localizing lesions, not for treating them. It states that it's "not intended for permanent implantation" and is used in conjunction with a gamma radiation detector for localization.
No
The device is used to mark lesions for localization rather than to identify or characterize them, and its function is to facilitate the use of a gamma radiation detector, not to perform a diagnosis itself.
No
The device description clearly details a physical medical device consisting of a radioactive seed contained within a needle, intended for implantation. This is a hardware device, not software.
Based on the provided information, the Lesion-Loc I-125 Seed/Needle is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The Lesion-Loc I-125 Seed/Needle is a device that is implanted directly into the human body (breast or other tissue) to mark a lesion. It does not analyze or test a sample taken from the body.
- The intended use is for localization within the body. The device is used in conjunction with a gamma radiation detector to physically locate a lesion within the patient's tissue. This is an in-vivo procedure, not an in-vitro (outside the body) diagnostic test.
- The device description details an implanted radioactive source. The core of the device is a radioactive seed intended for temporary placement within the body.
Therefore, the Lesion-Loc I-125 Seed/Needle falls under the category of an implantable medical device used for localization, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
Lesion-Loc I-125 Seed/Needle is indication of lesions (as shown by mamnogram or ultrasound) in the breast or other tissue under the direct supervision of a qualified physician. The device is "single-use sterile device". Lesion-Loc I-125 Seed/needle is not intended for permanant implantation and should be removed in a few days after implantation. It us to be used in conjunction with the Gammaprobe® (IntraMedical Imaging) for localization of lesions (as shown by a mammogram or ultrasound images) in the breast and other tissues.
The Lesion-Loc I-125 Seed/Needle is intended for clinical use in the marking of lesions with the seed in close proximity to or within the lesion site. The lesion (as seen in a mammogram or ultrasound image) is then located using an appropriate hand held gamma radiation detector.

Device Description
Lesion-Loc I-125 Seed/Needle contains a source 4.5 mm long and 0.8 mm in diameter. The source consists of a welded titanium capsule with a 0.05 mm thick wall and a silver rod, which is about 4 mm length with the active material as silver iodide on the surface, welded inside the titanium capsule. The seed is contained in a needle. The needles used are standard 18 gauges available commercially in lengths up to 15 cm. The I-125 seed is loaded inside the needle. The radioactive seeds are introduced into the lesion area as directed by a radiologist per Written Directive and prescription. The devices are packaged in a pouch with label and provided sterile.

- Lesion-Loc I-125 Seed/Needle contains a source 4.5 mm long and 0.8 mm in Device Description: diameter. The source consists of a welded titanium capsule with a 0.05 mm thick wall and a silver rod, which is about 4 mm length with the active material as silver iodide on the surface, welded inside the titanium capsule. The seed is contained in a needle. The needles used are standard 18 gauges available commercially in lengths up to 15 cm. The I-125 seed is loaded inside the needle. The radioactive seeds are introduced into the lesion area as directed by a radiologist per Written Directive and prescription. The devices are packaged in a pouch with label and provided sterile.
- Technological The Lesion-Loc I-125 Seed/Needle uses the Theragenics Corporation AgX100 characteristics (having a 510k number K103319) seed that typically has less radioactive strength than those used for brachytherapy. I-125 has a half-life of about 60 days and decays by electron capture with the emission of characteristic photons and electrons. The titanium walls of the seed absorb the electrons but the photons continue through the walls. An appropriate hand held gamma radiation detector probe is used to locate the seed and therefore also the lesion (as seen in a mammogram or ultrasound image).
- Performance The Lesion-Loc I-125 Seed/Needle is based on Theragenics Corporation AgX100 seed (having a 510k number K103319) design and commercially data available needle implant technology. Theragenics Corporation (Buford, GA, USA) contract manufactures the seed/needle device and provides the sterilized product to IntraMedical Imaging only after meeting all the performance qualification. A number of performance tests are done by Theragenics on the seed as per ISO 2919. IntraMedical Imaging distributes the Seed/Needle device for localization only as prescribed by a physician at a licensed hospital or other medical institution.
- Conclusion The technological characteristics and intended use of the Lesion-Loc I-125 Seed/Needle is substantially equivalent as the predicate device: Best® Localization Needle with I-125 Source.
Please note that the predicate Best Medical is identical in shape and size and the indication for use is also localization. Further conclusion is that also the OEM Theragenics Corporation Model AgX100 has been certified as safe, biocompatible and has been in clinical use for radiation therapy use without complaints.
