The Secure Lock transfer guide tubes have been developed to enable the connection of Varian's VariSource iX and 200 afterloaders and other third party applicators. This connection creates a conduit for the source wire to travel through and allows the radioactive isotopes to be positioned within the patient's turnor site.

Transfer guide tubes are non-myasive products that have no direct patient contact.

The Luer transfer guide tubes have been developed to enable the connection of Varian's VariSource iX and 200 afterloaders and other third party applicators that include a Luer style connection. This connection creates a conduit for the source wire to travel through and allows the radioactive isotopes to be positioned within the patient's tunnor site.

Transfer guide tubes are non-invasive products that have no direct patient contact.

The Luer interstitial extenders have been developed to enable the connection of Luer transfer guide tube to Kobold Interstitial Needles. This connection creates a conduit for the source wire to travel through and allows the radioactive isotopes to be positioned within the patient's tumor site.

Interstitial extenders are non-invasive products that have no direct patient contact.

Device Description

i) Kobold Secure Lock Transfer Guide Tube Set™
Each tube is numbered to ensure correct connection of the applicator channel with the corresponding afterloader channel. Only a physician who has been trained in the appropriate afterloader systems should use the Secure Lock transfer guide tubes. These transfer guide tubes are compatible with VariSource iX and VariSource 200 afterloaders.

ii) Kobold Interstitial Extender Set™
Each extender is numbered to ensure correct connection of the interstitial extenders and corresponding (1) transfer guide tube and (2) interstitial needle. Only a physician who has been trained in the appropriate afterloader systems should use the interstitial extenders.

AI/ML Overview

The provided document is a 510(k) premarket notification for two medical devices: the Kobold Secure Lock Transfer Guide Tube Set™ and the Kobold Interstitial Extender Set™. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting detailed clinical study results with acceptance criteria.

Therefore, the document does not contain the kind of information typically found in a study demonstrating how a device meets specific performance acceptance criteria. It primarily compares the new devices to existing predicate devices based on design, materials, indications for use, and general characteristics.

Here's a breakdown of why the requested information cannot be extracted from this document:

Acceptance Criteria and Reported Device Performance: This document does not list specific numerical acceptance criteria (e.g., sensitivity, specificity, accuracy thresholds) or detailed performance metrics from a study that evaluates these criteria. The approval is based on "substantial equivalence" to predicate devices.
Sample Size, Data Provenance, Ground Truth, Adjudication, MRMC, Standalone Performance, Training Set: These are elements of a clinical or performance study that are not included in a 510(k) summary focused on substantial equivalence for non-invasive accessory devices. The document explicitly states "Performance Tests: Not Required" for the conclusion summary (Page 7).
Type of Ground Truth: Since no clinical or performance study with a test set is described, there's no mention of how ground truth would be established (e.g., pathology, expert consensus).

The document does, however, discuss:

Bench Top Testing: On page 7, it states: "Extensive testing in accordance with known standards is documented by the manufacturer. The standards are specifications for the materials used in surgical implant applications, predicate brachytherapy devices and manufacturer's acceptance procedures for finished devices." This indicates that some internal technical testing was performed to ensure the device's functionality and material compliance, but specific results and acceptance criteria for these tests are not provided in this summary.
Substantial Equivalence: The core of this 510(k) is to demonstrate that the new devices are substantially equivalent to predicate devices. This means they share the same intended use, fundamental technological characteristics, and are as safe and effective. The tables provided (Pages 4-6) directly compare characteristics of the new devices with their predicates.

In summary, a table of acceptance criteria and proven device performance, as well as details about sample sizes, ground truth, and study methodologies, are not present in this 510(k) summary because the approval pathway relies on demonstrating substantial equivalence to existing devices rather than meeting specific performance thresholds through a new clinical or extensive performance study.

Dear Ms. Bernstein:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

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. 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); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Regulation Number and Section

§ 892.5700 Remote controlled radionuclide applicator system.

(a)
Identification. A remote controlled radionuclide applicator system is an electromechanical or pneumatic device intended to enable an operator to apply, by remote control, a radionuclide source into the body or to the surface of the body for radiation therapy. This generic type of device may include patient and equipment supports, component parts, treatment planning computer programs, and accessories.(b)
Classification. Class II.
