## Indications for Use

TheraLoad™ is a sterile prostate-seeding kit containing TheraSeed® (Pd-103) or I-Seed (I-125) seeds and spacers custom loaded according to the treatment plan. The brachytherapy source is intended to treat localized, unresectable turnors with low to moderate radiosensitivity. Tumors may be recurrent or residual following external beam or excision of primary tumor and may be superficial, intrathoracic (head, neck, lung), or intra-abdominal (pancreas, prostate).

## Device Story

TheraLoad™ is a sterile, single-use prostate-seeding kit containing radioactive seeds (Pd-103 or I-125) and bioabsorbable spacers. Treating medical physicists specify patient-specific prescriptions, determining the number of seeds and spacers (1-12 components) per needle based on a treatment plan. The device is used in clinical settings for brachytherapy. By providing pre-loaded needles, the device simplifies the implantation process for the physician, ensuring accurate delivery of the prescribed radiation dose to the tumor site. This targeted delivery benefits patients by treating localized, unresectable tumors while minimizing radiation exposure to surrounding healthy tissue.

## Clinical Evidence

Bench testing only. Design verification and validation were conducted in accordance with 21 CFR 820.30 to demonstrate compliance with performance specifications and safety requirements. Testing included sterilization validation, packaging integrity (ASTM F1140, F1886, F1929, F2096), and functional performance testing.

## Technological Characteristics

Sterile, single-use brachytherapy kit. Components: Pd-103 or I-125 seeds, bioabsorbable spacers. Sterilization: Radiation (AAMI TIR 27, ISO 11137). Packaging: ISO 11607 compliant. Sealed source classifications: ISO/99/C53211 (Pd-103) and ISO/99/C63211 (I-125).

## 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

- TheraSeed ([K010283](/device/K010283.md))
- I-Seed I-125 ([K021343](/device/K021343.md))
- Brachytherapy Strand Device ([K040339](/device/K040339.md))

Intended Use: TheraLoad™ is a sterile prostate-seeding kit containing TheraSeed® (Pd-103) or I-Seed (I-125) seeds and spacers custom loaded according to the treatment plan.

The brachytherapy source is intended to treat localized, unresectable turnors with low to moderate radiosensitivity. Tumors may be recurrent or residual following external beam or excision of primary tumor and may be superficial, intrathoracic (head, neck, lung), or intra-abdominal (pancreas, prostate).

Device Description: TheraLoad™ is a sterile prostate-seeding kit containing TheraSeed® (Pd-103) or I-Seed (I-125) seeds and bioabsorbable spacers custom loaded according to the treatment plan.

The variable seed spacing available with TheraLoad™ allows the treating medical physicist to specify individual patient prescriptions. The customized order can contain a variable number of seeds and/or spacers (1-12 total components). The treating medical physicist determines the total number of active seeds required for each order.

The spacer material is biocompatible and commonly used in implantable medical devices.

Dear Ms. Cortelloni:

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 (Premarket Approval), it may be subject to such 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. You must comply with all the Act's requirements, including, but not limited to registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

{5}------------------------------------------------

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter:

| 21 CFR 876.xxxx | (Gastroenterology/Renal/Urology) | 240-276-0115 |
|-----------------|----------------------------------|--------------|
| 21 CFR 884.xxxx | (Obstetrics/Gynecology)          | 240-276-0115 |
| 21 CFR 892.xxxx | (Radiology)                      | 240-276-0120 |
| Other           |                                  | 240-276-0100 |
