The device description and performance studies focus on the physical components and compatibility with imaging modalities, with no mention of AI or ML algorithms for image analysis, treatment planning, or any other function.
No
The device is a needle guidance system used for high dose rate irradiation, which is a treatment modality, but the device itself does not directly deliver therapy. Instead, it supports the delivery of therapy by guiding needles.
No
This device is a template and accessory system used for guiding needles during high-dose-rate irradiation for cancer treatment. Its purpose is to facilitate therapy delivery, not to diagnose a condition.
No
The device description clearly lists multiple physical components (template, obturator, tubes, collets, wrenches) and the performance studies focus on the physical properties and compatibility of these components with imaging modalities.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a "needle guidance system for the introduction of needles and a vaginal obturator into the treatment site" for high dose rate irradiation of cancers. This describes a device used in vivo (within the body) for a therapeutic procedure (radiation therapy).
- Device Description: The description details a physical template, obturator, tubes, and accessories used to guide needles for treatment. This aligns with a surgical or procedural device, not a device used to test samples in vitro (outside the body).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on laboratory testing.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
The CT/MR M.A.C. GYN Interstitial Template Set includes a labeled template, a slotted channel Vaginal Obturator, a set of intrauterine tubes in different angles, locking collets to accommodate both peripheral needle channels in the Template and needle channels in the central Vaginal Obturator, an Allen wrench to lock the intrauterine tube in the Obturator and a collet wrench to securely affix the needles by way of individual collets to both the Template and the vaginal obturator. The set features an Obturator - Template design with an optional intrauterine tube enabling complete or targeted treatment of the vagina, cervix, endometrium and parmetrium.
The Set is available in different gauge sizes to accommodate various needles. The associated Template, Obturator and collets are provided in the specified gauge size for use with the specific size needle indicated.
The Template is made of PPSU and medical grade Titanium. It is shaped optimally to conform to the patient's perineum to provide a more comfortable fit and to ensure better needle placement. The Template set includes a 14cm long central Vaginal Obturator (which is produced from Delrin) with a matrix of 6 needle channels positioned around the periphery of the Vaginal Obturator for individual needle placement. There is a 19cm long Vaginal Obturator as an available option. Both Obturators are 2.5cm in diameter. All Obturator Needles are secured with individual Locking Obturator Needle Collets
There is a peripheral matrix of needle channels that are positioned at 2 cm and 3 cm from the central axis around the Vaginal Obturator to further broaden the dose distribution, according to the treatment plan. Each Peripheral Needle is affixed individually by using the Peripheral Needle Collets. The collets used for the Vaginal Obturator and for the peripheral access needle channels have different threads but the same Collet Wrench is used by both to lock the respective collets in place for ease of use.
The components in the CT/MR M.A.C. Interstitial GYN Template are CT compatible and MR Conditional. This is achieved by using Titanium and plastic components that are inserted into the patient. This includes the Vaginal Obturator and the 3 tandems included in the set.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non Clinical Testing:
To operate in CT and MR environments, the CT/MR M.A.C. Interstitial GYN Template has been tested in a non-clinical environment, both for CT compatibility and for MR compatibility. CT compatibility testing has been performed and the results of the testing reveal very little artifacts and clinicians have certified that the CT images are not negatively impacted by artifacts due to the presence of the CT/MR M.A.C. Interstitial GYN Template and are of sufficient quality for use in the radiation therapy clinical workflow.
In order to operate in the MR environment, testing has been performed using both 1.5T and 3.0T scanners to validate the fact the due to the materials used and the geometry of the device there are favorable results achieved in the testing The tests performed measured the displacement, torgue, artifact results and heating results.
The calculated displacement force corresponded to an assumed displacement of 1 degree and the calculated force in all cases was less than that associated with gravity, in accordance with the relevant standard. No torque effect was observed on the CT/MR M.A.C. Interstitial GYN Template with associated devices at approximate isocenter of the 3.0T magnet when the device was caused to rotate through three complete revolutions.
For image artifacts, the maximal extent of artifact associated with portions of the device expected to be within the body of the patient was 4.8cm on a 3.0T gradient-echo image. Observed artifacts were consistent with expectations due to the metallic construction.
Heating testing was performed using both the 1.5T and 3.0T scanners and the results of the testing indicate that with the application of a limitation to the Normal Operating Mode at a SAR of 1.0W/kg, the largest expected total temperature rise at the limiting field strength, with 15 minutes of scanning is less than 6°C. This level of heating is not expected to cause adverse effects. All comprehensive test data and results are on file.

7. Predicate Device Rationale and Substantial Equivalence Discussion PRIMARY PREDICATE
CT/MR M.A.C. Interstitial GYN Template is designed to take advantage of two separate device technologies manufactured by Mick Radio-Nuclear Instruments. Inc. It takes the intracavitary features of the HDR Miami Applicator and combines this with a grid pattern for interstitial needle placement, similar to the HDR Contour TP Template. The grid pattern is shaped in a circular pattern around a central obturator enabling complete or targeted treatment of the vagina, cervix, endometrium and parmetrium. Like the Miami Applicator, the CT/MR M.A.C. Interstitial GYN Template features a central obturator for intracavitary needle guidance as well as additional needle channels around the periphery. The Obturator contains the features of the HDR Miami Applicator, combined with a template or grid design. This provides a very flexible device, allowing a wide variety of needle placement, both in the Template field and through the use of the vaginal obturator. The design and manufacturing process for the CT/MR M.A.C. Interstitial GYN Template is identical to both primary predicate devices and share similar materials.
The HDR Miami Applicator has been marketed since 2002 as a GYN treatment device and the CT/MR M.A.C. Interstitial Template shares many of the same features. notably the use of the vaginal obturator and intrauterine tubes. In the Miami Applicator, the obturator is utilized to introduce an HDR source directly into the obturator and the CT/MR M.A.C. Interstitial Template uses an obturator of the same design to introduce the HDR source through flexible or rigid needles or through an intrauterine tube, identical to the Miami Applicator. The utilization of an intrauterine tube allows for flexible and widespread treatment of the cervix and endometrium. The needle grid of the CT/MR M.A.C. Interstitial Template has a central opening that allows the passage and placement of the vaginal obturator into the treatment site. The obturator is positively affixed by the use of a locking knob which allows for a very secure placement to the desired treatment depth.
SECONDARY PREDICATE
The HDR Contour Template is a needle guidance device intended for Prostate Brachytherapy and has been marketed and used since 1999. The template design is shaped to comfortably fit against the perineum and is also compatible to several ultrasound stepping units. The CT/MR M.A.C. Interstitial GYN Template shares these these features. The CT/MR M.A.C. Interstitial Template needle grid is based on the proven principles of the HDR Contour Template while conforming to the GYN treatment site. The needle grid pattern is shaped to allow needle placement in the target treatment area, throughout the entire vagina. Mick Radio-Nuclear Instruments, Inc. utilizes the same template manufacturing process and expertise in manufacturing templates to very exacting standards of operation and this experience and knowledge is used to produce the CT/MR M.A.C. Interstitial GYN Template to the same high standards and tight tolerances required of needle placement templates.
The Alpha Omega Interstitial Templates, Needles and Accessories were chosen as a reference device based on a similar intended use and the ability to provide a fixed array of needles and a vaginal guide into the treatment site. This device shares the same
6
treatment modality as the CT/MR M.A.C. Interstitial Template, however there are significant differences. The vaginal guide (or obturator) is affixed by the use of an O-Ring which is not used in the CT/MR M.A.C. Interstitial Template. Also the materials used in the Alpha Omega device are made from silicone and the manufacturing process are not the same. The Alpha Omega device also is provided sterille is single use and the CT/MR M.A.C. Interstitial Template is not provided sterile but is reusable.
Summary of Similarities and Differences 8.
The similarities between the CT/MR MAC Interstitial GYN Template and the HDR Miami Applicator is the use of the same material and design in the vaginal obturators. The indications for use are the same in both applicators. The same principles and design have been used for the obturator in the CT/MR MAC Interstitial GYN Template.
The same technology is used for aligning the needles along the periphery of the obturator (6 individual channels to a prescribed depth) and the same technology and design is used for the introduction into and the locking of the central intrauterine tubes onto the obturator. There are similar lock knobs used to positively affix the intrauterine tube to the desired depth of penetration through the cervix and into the uterus for treatment. Both applicators are reusable.
The Template Body of the CT/MR MAC Interstitial GYN Template shares the same design as the HDR Contour Template; however, the needle channel pattern is different in order to suit the anatomy. The shape of the templates are similar in order to fit the perineum and the needles in both templates can be positively locked in place using individual collets to ensure the safe and effective treatment. Needle sizes are variable to accommodate various treatment plans. Both applicators are reusable.
The operating principles are the same in the predicates named. All of the devices are used to introduce an HDR source into the treatment site through a central obturator, an intrauterine tube or a hollow needle. There is no electrical energy used in the operation of the devices
9. Manufacturing Process
This device is manufactured according to Good Manufacturing Practices (GMPs) as defined in 21CFR part 820. The processes used to fabricate the CT/MR MAC Interstitial GYN Template is very similar to the two Mick Radio-Nuclear Instruments devices identified as primary predicate devices described in this 510(k) notification.
10. Biocompatibility
No new issues of biocompatibility are raised with regard to the introduction of the CT/MR MAC Interstitial GYN Template. Medical grade materials are used in the manufacture of this device.
However, biocompatibility testing has been performed on an applicator made from the same materials as the CT/MR MAC Interstitial GYN Template and considered a worst case scenario from device construction.

11. Non Clinical Testing
To operate in CT and MR environments, the CT/MR M.A.C. Interstitial GYN Template has been tested in a non-clinical environment, both for CT compatibility and for MR compatibility. CT compatibility testing has been performed and the results of the testing reveal very little artifacts and clinicians have certified that the CT images are not negatively impacted by artifacts due to the presence of the CT/MR M.A.Č. Interstitial GYN Template and are of sufficient quality for use in the radiation therapy clinical workflow.
In order to operate in the MR environment, testing has been performed using both 1.5T and 3.0T scanners to validate the fact the due to the materials used and the geometry of the device there are favorable results achieved in the testing The tests performed measured the displacement, torgue, artifact results and heating results.
The calculated displacement force corresponded to an assumed displacement of 1 degree and the calculated force in all cases was less than that associated with gravity, in accordance with the relevant standard. No torque effect was observed on the CT/MR M.A.C. Interstitial GYN Template with associated devices at approximate isocenter of the 3.0T magnet when the device was caused to rotate through three complete revolutions.
For image artifacts, the maximal extent of artifact associated with portions of the device expected to be within the body of the patient was 4.8cm on a 3.0T gradient-echo image. Observed artifacts were consistent with expectations due to the metallic construction.
Heating testing was performed using both the 1.5T and 3.0T scanners and the results of the testing indicate that with the application of a limitation to the Normal Operating Mode at a SAR of 1.0W/kg, the largest expected total temperature rise at the limiting field strength, with 15 minutes of scanning is less than 6°C. This level of heating is not expected to cause adverse effects. All comprehensive test data and results are on file.
