The Single Use Cannula V PR-V223Q/V414Q/V416Q/V418Q/V420Q/V427Q/V434Q/V435Q are intended to be used to inject contrast medium in the biliary or pancreatic duct in combination with an endoscope.
The Single Use 2-Lumen Cannula V PR-V614M is intended to be used to inject contrast medium in the biliary or pancreatic duct in combination with an endoscope.
The Single Use Cannula V and the Single Use 2-Lumen Cannula V PR Series is comprised of nine (9) sterile, single-use, cannulas designed to inject contrast medium in the biliary or pancreatic duct when used in conjunction with a compatible endoscope.
Each device has two sections: the handle (proximal portion) and the insertion portion. The insertion portion is introduced into the biliary or pancreatic ducts through an endoscope. The distal end of the insertion portion is designed for smooth cannulation of the papilla of Vater or the minor papilla. All models are visible under fluoroscopy and feature a distal marking system.
The Single Use Cannula V and the Single Use 2-Lumen Cannula V PR Series models are to be used with compatible endoscopes.
The provided 510(k) Premarket Notification document describes a medical device, the "Single Use Cannula V and the Single Use 2-Lumen Cannula V PR Series," and its comparison to a predicate device for demonstrating substantial equivalence.
However, the document does not contain information about acceptance criteria or a study proving the device meets specific acceptance criteria in the context of device performance as typically expected for software-enabled devices or those with diagnostic capabilities.
This submission is for a physical medical device (cannulas) and focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance testing of its physical properties and biocompatibility. Therefore, many of the requested categories (like sample size for test/training sets, data provenance, number/qualifications of experts, adjudication methods, MRMC studies, standalone performance, and ground truth types) are not applicable to the information provided.
Based on the document, here's what can be extracted and what cannot:
1. Table of Acceptance Criteria and Reported Device Performance:
The document outlines performance data that was provided to demonstrate substantial equivalence, rather than specific and quantitative acceptance criteria with reported numerical device performance against those criteria. The "Analysis" column in the comparison table broadly states "Substantially equivalent" or "Identical," but doesn't provide the detailed numbers that would typically be associated with acceptance criteria for a diagnostic or algorithmic device.
| Performance Data Category | Description |
|---|---|
| Biocompatibility | Cytotoxicity, Sensitization, Irritation, Acute Systemic Toxicity, Material-Mediated Pyrogenicity |
| Sterilization Validation | Per ISO 11135:2014 |
| Ethylene Oxide Residuals | Per ISO 10993-7:2008 |
| Packaging Validation & Shelf Life | Per ISO 11607-1:2019 and ASTM F1980-21 |
| Mechanical Testing & Comparative Testing | Insertion force/Withdrawal force, Insertion w/ Stylet, Attachment and detachment of the hook, Contrast medium infusion, Connection strength, Visibility |
| Human Factors Testing | Verification of device performance |
Acceptance Criteria and Reported Performance (General statement from the document):
The document states: "Non-clinical testing demonstrates that the slight differences in device design do not alter the safety, efficacy, or performance of the subject devices when compared to the predicate devices." and "The non-clinical data demonstrate that the subject device is as safe, as effective, and performs as well as or better than the identified predicate device." This is a qualitative conclusion of meeting equivalence rather than presenting specific numerical acceptance criteria.
2. Sample size used for the test set and the data provenance:
- Sample Size for Test Set: Not specified in the provided document. The performance data refers to various non-clinical tests, and the sample size for these individual tests (e.g., number of cannulas tested for insertion force) is not detailed.
- Data Provenance: Not applicable in the context of clinical data. The tests are non-clinical (laboratory/bench testing).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. Ground truth as typically understood for diagnostic performance (e.g., disease presence/absence) is not relevant for these non-clinical, physical device performance tests. "Human Factors Testing" is mentioned, which would involve experts, but the number and qualifications are not provided, nor is it the type of "ground truth" establishment usually refers to in the context of diagnostic AI.
4. Adjudication method for the test set:
- Not applicable. This is typically used for clinical study endpoints or image interpretation, not for physical performance tests of a cannula.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- Not applicable. This device is a physical cannula, not an AI or diagnostic imaging system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an algorithm or AI device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not applicable in the conventional sense. The "ground truth" for the non-clinical tests would be the physical properties and functional performance measured against predefined specifications or predicate device performance.
8. The sample size for the training set:
- Not applicable for a physical device where "training set" doesn't apply in the context of machine learning.
9. How the ground truth for the training set was established:
- Not applicable for a physical device.
§ 876.1500 Endoscope and accessories.
(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.
