## Indications for Use

The BEBIG I-125 sources are intended for use in the treatment of cancer with radioactive sources in close proximity to or within the tumor.

## Device Story

BEBIG IsoSeeds I-125 are cylindrical sealed brachytherapy sources (4.5mm length, 0.8mm diameter) containing iodine-125 radioactivity. Iodine-125 is deposited as silver iodide (AgI) within a porous ceramic tube containing a gold alloy radiopaque marker. The titanium capsule is laser-welded at both ends. The device emits characteristic photons and electrons; the titanium wall absorbs electrons. Sources are provided nonsterile for clinical use in treating localized tumors via implantation. The device is used by clinicians to deliver localized radiation therapy to tumors, potentially benefiting patients by providing targeted treatment.

## Clinical Evidence

No clinical data. Bench testing only.

## Technological Characteristics

Cylindrical sealed source; titanium capsule (ASTM F67-95); iodine-125 radioactive isotope; gold alloy radiopaque marker; porous ceramic carrier. Dimensions: 4.5mm x 0.8mm. Sterilization required post-manufacture. Complies with ISO 2919 and ISO 9978.

## Regulatory Identification

A radionuclide brachytherapy source is a device that consists of a radionuclide which may be enclosed in a sealed container made of gold, titanium, stainless steel, or platinum and intended for medical purposes to be placed onto a body surface or into a body cavity or tissue as a source of nuclear radiation for therapy.

## Special Controls

*Classification.* Class II (special controls). A prostate seeding kit intended for use with a radionuclide brachytherapy source only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

## Predicate Devices

- UroMed Brachytherapy Iodine-103 Source ([K982226](/device/K982226.md))

## Intended Use

The BEBIG I-125 sources are intended for use in the treatment of cancer with radioactive sources in close proximity to or within the tumor.

## Indications for use

The BEBIG brachytherapy I-125 sources are indicated for the treatment of selected localized turnors. These sources are commonly used to treat superficial, intra-abdominal and intrathoracic tumors. Tumors of the head, neck, lung, pancreas and prostate are commonly treated. They may be used alone, or in combination with external beam radiation.

#### Description

The BEBIG I-125 sources are cylindrical sealed sources containing iodine-125 radioactivity. The sources are 4.5 mm long and 0.8 mm in diameter. The outer capsule of the source is composed of titanium, and is sealed at each end by laser weld. The iodine-125 is deposited within a porous ceramic tube as silver iodide (AgI). A radiopaque marker is located in the center of the ceramic tube to serve as an x-ray marker. The radiopaque marker is composed of gold alloy.

I-125 has a half live of 59.46 days and decays by electron capture with emission of characteristic photons and electrons. The titanium wall of the I-125 source absorbs the electrons.

The BEBIG I-125 sources are available in a range of activity levels. They are provided nonsterile and must be sterilized before use.

Dear Mr. Langer:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
