The EndoGl S-Path Biliary Stent System is intended for delivery of stent(s) to the biliary tract for drainage of the bile ducts, for splinting of a bile duct during healing, or for providing bile duct patency in a stricture or past a stone.
The revised EndoGI S-Path System incorporates one preloaded stent which has a straight body and one end incorporating a 65° bend (duodenal bend). The stent is identical to the previously cleared EndoGI stent and is comprised of a biocompatible radiopaque plastic which allows visualization of the stent post deployment.
The EndoGI S-Path System is available 10 Fr and includes a single preloaded stent available in three lengths (80, 110 and 140 mm). The system is compatible with a guidewire of up to 0.035".
The provided text is a 510(k) summary for the EndoGI S-Path Biliary Stent System. It primarily focuses on demonstrating substantial equivalence to a predicate device based on intended use, technology, and performance data from mechanical, dimensional, biocompatibility, and sterilization tests. It does not contain information about clinical study acceptance criteria or the specifics of a clinical study aimed at proving device performance against such criteria.
Therefore, I cannot provide the requested information from the given text. The document does not describe:
- A table of acceptance criteria and reported device performance.
- Sample size for a test set or its provenance.
- Number or qualifications of experts used for ground truth.
- Adjudication method for a test set.
- Multi-reader multi-case (MRMC) comparative effectiveness study or effect size.
- Standalone (algorithm-only) performance.
- Type of ground truth used (expert consensus, pathology, outcomes data, etc.).
- Sample size for a training set.
- How ground truth for a training set was established.
The document discusses "performance data" in a general sense within Section 7, referring to mechanical performance, dimensional testing, and kink tests, as well as biocompatibility and sterilization tests to support modifications made to the delivery system. These are typically engineering and laboratory tests, not clinical performance studies with human subjects or expert readers that would generate the kind of data requested in the prompt.

EndoGI Medical, Ltd.
The EndoGI Biliary Stent System is intended for delivery of stent(s) to the biliary tract for drainage of the bile ducts, for splinting of a bile duct during healing, or for providing bile duct patency in a stricture or past a stone.
The EndoGI System incorporates two preloaded stents. Both stents are identical in design with a straight body and one end incorporating a 65° bend (duodenal bend). The stents are comprised of a biocompatible radiopaque plastic which allows visualization of the stents post deployment. Both stents are pre-mounted on the delivery system and are delivered via near-the-wire and over-the-wire methods. The EndoGI System is available 10 Fr and includes two 110 mm stents. The system is compatible with a guidewire of up to 0.035". The safety lock mechanisms are incorporated within the delivery device handle.
The provided text describes the EndoGI Biliary Stent System and its substantial equivalence to a predicate device, primarily through bench and animal testing. It does not contain information about an AI/ML powered device, therefore, many requested sections about human readers, ground truth establishment for training, and sample sizes for training/test sets are not applicable.
However, I can extract information related to the performance testing and acceptance criteria as presented for the non-AI medical device.
1. Table of Acceptance Criteria and Reported Device Performance
Feature/Test | Acceptance Criteria | Reported Device Performance |
---|---|---|
Material (Biocompatibility) | Biocompatibility tests for stent and delivery system. | Stent and delivery system successfully passed: Systemic Toxicity (Implant Method), Implant Evaluation Test in Rabbits, Systemic Toxicity (Dual Route Repeated Exposure Method) Test, Material Mediated Pyrogenicity Test, Acute Systemic Toxicity Test, Guinea Pig Maximization Test, Intracutaneous Reactivity Test, Mouse Lymphoma Assay, Ames Bacterial Reverse Mutation Assay, MEM Elution Cytotoxicity Assay. |
Mechanical Evaluation | Meets performance standards for: Kink Resistance, Flow Rate, Bond Strength, Dimensional Verification, Compression Force (Bile), Tensile Test (Bile). | EndoGI Biliary Stent System device successfully passed all listed mechanical evaluation tests. Obtained results supports substantial equivalency claim for Tensile test, Compression test, and Flow Rate. |
Two Stent Deployment | System able to successfully deliver 2 stents utilizing a one-step procedure, no local tissue reaction, and successful stent removal. | Animal study (GLP-like on porcine model) demonstrated successful delivery of 2 stents in one-step, no local tissue reaction, and successful stent removal across 6 repeats. Average procedure duration was 20 minutes; second stent deployment within 1 minute. |
2. Sample size used for the test set and the data provenance
The document does not explicitly define a "test set" in the context of an AI/ML device. For the animal study, the sample size was 6 repeats on a porcine model. The provenance is an animal model, specifically a "GLP-like animal study on porcine model," which implies a controlled, prospective study designed to evaluate product performance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable as this is not an AI/ML powered device requiring expert ground truth for image interpretation or diagnosis. The "ground truth" for this device's performance is derived from physical and biological observations during bench and animal testing.
4. Adjudication method for the test set
Not applicable. The "test set" here refers to the physical and biological tests, not a dataset requiring adjudication.
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 is not an AI/ML powered device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI/ML powered device. The device's "standalone" performance is evaluated through the specified bench and animal tests.
7. The type of ground truth used
For the bench testing (e.g., mechanical evaluations), the ground truth is based on engineering specifications and measurable physical properties.
For the animal study, the ground truth is based on direct observation of successful stent delivery, absence of local tissue reaction, and successful stent removal by the study investigators.
8. The sample size for the training set
Not applicable as this is not an AI/ML powered device.
9. How the ground truth for the training set was established
Not applicable as this is not an AI/ML powered device.
