The Sialo Balloon Dilatation Catheter is designed to allow dilatation of the salivary duct under endoscopic or radiological guidance. Dilatation can be therapeutic by itself (for duct strictures), or provide endoscopic access for stone removal.

AI/ML Overview

The provided 510(k) summary for the Sialo Balloon Dilatation Catheter (K072749) does not contain information about specific acceptance criteria or an associated study that proves the device meets those criteria in the way typically expected for an AI device.

This document describes a surgically invasive medical device (a balloon catheter), not an AI/ML software device. The regulatory submission focuses on demonstrating substantial equivalence to predicate devices through performance testing related to the physical device's safety and functional specifications, rather than clinical performance metrics in the context of an AI algorithm.

Therefore, many of the requested categories (e.g., sample size for test set, number of experts, adjudication methods, MRMC study, standalone performance, ground truth for training set) are not applicable to this type of device and are not present in the provided text.

However, I can extract the relevant information regarding performance testing that was conducted.

Summary of Performance Testing for K072749: Sialo Balloon Dilatation Catheter

Section	Acceptance Criteria	Reported Device Performance
1. Acceptance Criteria & Performance	Device met all its functional specifications.	"extensive safety, performance, and validation testing before release." "various performance tests designed to ensure that the device met all its functional specifications." "Tests have been performed to ensure the device complies with industry and safety standards."

Study Details (based on available information):

2. Sample size used for the test set and data provenance:
- Not applicable/Not provided. The testing described is for the physical device's performance (e.g., mechanical properties, sterility, integrity) rather than clinical data analysis with a test set.
3. Number of experts used to establish the ground truth for the test set and qualifications of those experts:
- Not applicable/Not provided. Ground truth in this context would relate to clinical outcomes or diagnoses, which is not the focus of the described device performance testing.
4. Adjudication method for the test set:
- Not applicable/Not provided.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs without AI assistance:
- No. This is not an AI device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- No. This is not an AI device.
7. The type of ground truth used:
- Not applicable/Not provided in the sense of clinical ground truth for diagnostic accuracy. The "ground truth" for this device's performance would relate to engineering specifications and safety standards (e.g., balloon integrity, catheter flexibility, material biocompatibility, burst pressure).
8. The sample size for the training set:
- Not applicable/Not provided. This is not an AI device that would have a "training set."
9. How the ground truth for the training set was established:
- Not applicable/Not provided.

Additional Information from the document:

Type of Study: The submission describes "extensive safety, performance, and validation testing" including "various performance tests designed to ensure that the device met all its functional specifications" and compliance with "industry and safety standards." It also mentions a "Literature review describing device use in other countries." These are typical for medical device regulatory submissions that focus on physical and functional characteristics.
Intended Use: Dilatation of the salivary duct for therapeutic purposes (strictures) or to provide endoscopic access for stone removal.
Predicate Devices:
- The Salivary Duct Dilator (Cook Medical) - a rigid rod for mechanical dilatation.
- KSEA Sialoendoscope and accessories (Karl Storz Endoscopy) - an endoscopic device.
- Dilatation Catheter Ascend™ Balloon (K970041) (Cook Urological).
Conclusion of the Submission: The Sialo Balloon dilatation device is substantially equivalent in safety and efficacy to the predicate devices listed.

(K970041) Dilatation Catheter Ascend™M Balloon - The manufactured by Cook Urological.

Sialo Balloon Dilatation Catheter is designed to allow dilatation of Device Description: the salivary duct under endoscopic or radiological guidance. Dilatation can be therapeutic by itself (for duct strictures), or provide endoscopic access for stone removal.

Intended Use / Indication for Use: The Sialo device is a medical device for use by qualified surgeons in the treatment of salivary gland diseases.

Performance Standards: None.

The Sialo Balloon dilatation device has been subjected to extensive Test Data: safety, performance, and validation testing before release. Final testing of the Sialo device included various performance tests designed to ensure that the device met all its functional specifications. Tests have been performed to ensure the device complies with industry and safety standards. Literature review describing device use in other countries is provided in Section 21 of this submission.

The Sialo Balloon dilatation device is similar to currently Substantial Equivalence: distributed endoscopic accessory devices intended for treatment of other strictures in other body cavities; and it is similar in intended use to the Cook salivary duct dilator. Dilatation balloon catheters are used through endoscopic working channels to dilate a variety of ducts/ tubes, such as dilatation balloons for the biliary duct, for the urinary tract, for the lacrimal duct, and for dilatation of blood vessels. All of the above features are similar to these features in the predicate devices.

The conclusions drawn from the above Performance Testing and Conclusions: comparison to predicate devices, is that the Sialo Balloon dilatation device is substantially equivalent in safety and efficacy to the predicate devices listed above.
