Source Production & Equipment Co., Inc. Model M14 192Iridium Brachytherapy Source, with individual activity up to 12 Ci, is indicated for temporary interstital, intraluminal, intraoperative or surface application to treat selected localized tumors. This source can be used as primary treatment for a variety of anatomical sites commonly treated with high dose rate brachytherapy, including the cervix, vagina, endometrium, rectum, esophagus, bronchus, head and neck, bile duct, brain, skin, prostate, lung, pancreas, and breast and for treatment of sarcomas and for intraoperative radiation therapy. This source may be used concurrently with or following treatment with external beam radiation therapy.
The source is designed for use in medical brachytherapy applications and may only be used in conjunction with the Elekta/Nucletron V2/V3 Afterloaders.
The intended use of the Source Production & Equipment Co., Inc. Model M14 194ridium Brachytherapy Source is for the treatment of cancer by temporary interstitial, intracavitary, intraluminal, intraoperative or surface irradiation.
Source Production & Equipment Co., Inc. Model M14 194ridium Brachytherapy Source is a singly-encapsulated 192 ridium Brachytherapy Source. It consists of a stainless steel capsule containing a solid radioactive 1921ridium pellet is sealed in a stainless steel capsule that is attached to a cable to permit manipulation by the remote afterloading system.
The source consists of a solid 192Iridium pellet (0.6 mm dia x 3.5 mm long) singly encapsulated in stainless steel (0.9 mm dia x 4.8 mm long) and welded to a 7x7 stranded stainless steel cable (0.9 mm dia x 2022 mm long).
The provided text is a 510(k) Premarket Notification for a medical device: the Source Production & Equipment Co., Inc. Model M14 192Iridium Brachytherapy Source. This type of FDA submission focuses on demonstrating substantial equivalence to a previously legally marketed predicate device, rather than proving stand-alone safety and effectiveness through extensive clinical trials as would be required for a novel, high-risk device.
Therefore, the document does not contain the information requested regarding acceptance criteria and study details for AI/ML-based medical devices (e.g., acceptance criteria tables, sample sizes for test sets, data provenance, expert ground truth establishment, MRMC studies, standalone algorithm performance, or training set details).
The information provided describes:
- The device description (a singly-encapsulated 192Iridium Brachytherapy Source).
- Its intended use (treatment of cancer via temporary interstitial, intracavitary, intraluminal, intraoperative, or surface irradiation).
- Its technological characteristics in comparison to a predicate device (SPEC Model M15).
- Nonclinical tests performed to demonstrate equivalence:
- Physical Testing: Subjected to ANSI N43.6 and ISO 2019 standards, meeting Class C53211 requirements (equivalent to predicate).
- Tensile Testing: Prototype sources subjected to tensile loads and fatigue tests exceeding maximum forces applicable by the afterloader (demonstrating sufficient strength, equivalent or better than predicate).
- Operational Testing: Prototype successfully navigated curved pathways and endured over 50,000 exposure/retract cycles in an afterloader without failure (equivalent to predicate).
- Dosimetry: Dose distribution calculated by Monte Carlo simulation in accordance with AAPM and ESTRO recommendations (equivalent to predicate).
- Clinical Tests: Stated as "Not Applicable," which is common for substantial equivalence claims where nonclinical data are deemed sufficient.
In summary, the document demonstrates that the new device is functionally identical to a previously cleared device for its intended use, based on nonclinical performance data that meets established industry standards. It does not present data related to acceptance criteria or studies as typically described for AI/ML-driven diagnostics where performance metrics like sensitivity, specificity, or reader improvement are key.

Nonclinical Tests (1)
Physical Testing
The Source Production & Equipment Co., Inc. Model M14 194ridium Brachytherapy Source has been subjected to the tests specified in American National Standard (ANSI) N43.6 and International Organization for Standardization (ISO) Standard 2019, as referenced in the FDA "Guidance for the Submission of Premarket Notifications for Photon-Emitting Brachytherapy Sources" dated 2 August 2000.
Prototype sources were subjected to the tests specified in ANSI N43.6-2007 and ISO 2919-2012 and have equaled or exceeded the requirements corresponding to a classification of C53211, which is the requirement for brachytherapy sources. This is equivalent to the physical testing of the predicate device.
Tensile Testing
The ultimate criteria for these categories of weld is to have sufficient tensile strength for the application. As described in Registry of Radioactive Sealed Sources and Devices Safety Evaluation of Source No. MD-0497-S-107-S, all welded connections of the sources used in the Elekta/Nucletron V2/V3 Series High Dose Rate (HDR) are mechanically tested by a pull test of 15 N of force. We have conservatively interpreted this value to be the maximum force that the afterloader can apply to the source assembly. We believe this is conservative because if the afterloader could apply a greater force than this, Nucletron would have applied a greater tensile test requirement. In all likelihood, the maximum force that can be applied to the source assembly would be less than this value. Therefore, under this interpretation, we have adopted a production tensile test requirement that is 2.5 times this specified force or 37.5 Newtons (8.4 lbs).
Prototype sources were subjected to a series of tensile fatigue tests consisting of:
- a tensile load in excess of 45 N (10 lb). which is more than 2.5 times the . maximum force than can be applied to the cable by the Elekta/Nucletron V2/V3 Series HDR Afterloader
- ten sequential applications of a tensile load of in excess of 22 N (5 lbs) which is . more than the maximum load that can be applied by the Elekta/Nucletron V2/V3 Series HDR Afterloader, and then
- a tensile load in excess of 45 N (10 lb). which is more than 2.5 times the . maximum force than can be applied to the cable by the Elekta/Nucletron V2/V3 Series HDR Afterloader
- and finally a tensile load to failure of each of the welds of the source assembly, . where the minimum failure load was 138 N (31 lb) which is more than 9 times the maximum force that can be applied by the Elekta/Nucletron V2/V3 Series HDR Afterloader.
{7}------------------------------------------------
Image /page/7/Picture/0 description: The image shows the word "spec" in a bold, outlined font. To the right of the word is a radiation symbol. The word and symbol are in black and white.
It is concluded that the tensile strength of this source assemble is sufficient for its intended application. This is equivalent to or better than the tensile testing of the predicate device.
Operational Testing
A prototype source assembly was subjected to a curved pathway performance test consisting of driving the source cable through a series of "S" and "U" curves with a variety of radii which simulate the various pathways of applicators used with the Elekta/Nucletron V2/V3 Series HDR Afterloader. The source capsule and cable successfully negotiated all of these pathways. There was no damage to the M14 source assembly.
Subsequently, the same source assembly was subjected to an endurance performance test in an Elekta/Nucletron V2/V3 Series HDR Afterloader, where the source assembly performed more than 50.000 exposure/retract cvcles. As a result of these tests, there was no failure of the source cable, the source capsule or the connection of the source capsule to the source cable.
This is equivalent to the physical testing of the predicate device.
Dosimetry
The dose distribution around the Source Production & Equipment Co., Inc. Model M14 192 ridium Brachytherapy Source was calculated by Monte Carlo simulation in accordance with the recommendations of the American Association of Physicists in Medicine and the European Society for Therapeutic Radiation Oncology. 1 This is equivalent to the dosimetry of the predicate device.

(2) Clinical Tests

(3) Conclusions
The results of the nonclinical physical, tensile, operational tests and the dosimetric analysis, demonstrate that the Source Production & Equipment Co., Inc. Model M14 192 ridium Brachytherapy Source is as safe, as effective, and performs as well or better than the legally marketed predicate device, SPEC Model M15 High Dose Rate Brachytherapy Source.
