The ClearPath-UGI System is intended for irrigating or cleaning the upper digestive tract and evacuating the irrigation fluid, blood and bile in the upper GI tract during endoscopic procedures. It is for use only by trained medical personnel located in hospitals, clinics, and doctors' offices.
The ClearPath UGI's main purpose is to improve procedure reliability by improving procedural visualization during endoscopic procedures. The ClearPath UGI utilizes a suction / irrigation head for the purpose of irrigating or cleaning the upper digestive tract. The ClearPath UGI is composed of two major units: . The disposable Irrigator and . the reusable Control cabinet. The disposable Irrigator is attached to a standard endoscope by means of silicone bands and does not hinder the endoscope's functionality nor affects the procedure sequence in any way. The Control cabinet supplies the water flow and vacuum control using a peristaltic pump. The standard medical facility vacuum system is the vacuum source.
The provided text describes the ClearPath UGI device and its 510(k) submission for substantial equivalence. However, it does not contain information about a study that proves the device meets acceptance criteria in terms of clinical performance, efficacy, or specific performance metrics beyond simple engineering specifications.
Instead, the document focuses on demonstrating substantial equivalence to a predicate device based on:
- Identical indications for use.
- Identical technology.
- Identical patient-contact materials.
- Identical environment of use.
- Identical performance specifications (Air/Water pressure, Flow rate, Suction specifications).
Therefore, I cannot populate the table and answer several of your questions as the requested information (related to a clinical study, reader performance, ground truth, and training data) is not present in the provided text.
Here's the information that can be extracted or inferred based on the provided document:
1. Table of acceptance criteria and the reported device performance:
| Acceptance Criteria (Predicate Device K091305) | Reported Device Performance (Proposed ClearPath UGI) |
|---|---|
| Air / Water pressure: Up to 30 Psi | Up to 30 Psi |
| Flow rate: Up to 300 ml/min | Up to 300 ml/min |
| Suction specifications: Approx. 0.5 Bar | Approx. 0.5 Bar |
| Primary Goal: Improve procedural visualization during endoscopic procedures | The claim is "improve procedure reliability by improving procedural visualization." |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
Not applicable. The document describes engineering specification comparisons, not a clinical test set.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
Not applicable. Ground truth for clinical performance was not established in the provided context. The "ground truth" here is the published specifications of the predicate device.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. No clinical test set or adjudication is mentioned.
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 not an AI diagnostic tool and no MRMC study is mentioned.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
Not applicable. This is not an AI algorithm; it's a physical medical device accessory.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
For the purpose of substantial equivalence, the "ground truth" used are the engineering specifications and performance characteristics of the predicate device (K091305 – Easy Glide – ClearPath). The new device's performance was compared against these established specifications.
8. The sample size for the training set:
Not applicable. No training set is mentioned as this is not an AI/machine learning device.
9. How the ground truth for the training set was established:
Not applicable. No training set or associated ground truth establishment is mentioned.
Summary of the Study (as described in the document):
The "study" described in the 510(k) summary is a benchtop comparison against a predicate device (K091305 – Easy Glide – ClearPath). The purpose was to demonstrate substantial equivalence for the modified ClearPath UGI device, which has a shorter disposable tubing set and a redesigned irrigation tip, but no modifications to the controller or software.
The study involved confirming that the key performance specifications of the proposed device (Air/Water pressure, Flow rate, Suction specifications) are identical to those of the predicate device. This was presented as "testing to demonstrate that the operating performance of the ClearPath UGI is equivalent to the predicate for flow rate, irrigation and vacuum pressures."
The acceptance criteria were simply that the new device's engineering performance for these specific parameters should match those of the legally marketed predicate device. The document states, "Performance specifications - Irrigation pressures, flow rate and suction pressures are identical to the predicate -. K091305 EasyGlide ClearPath."
§ 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.
