Intended Use

The Tip-Shape Echelon™ Micro Catheter is intended to access peripheral and neuro vasculature for the controlled selective infusion of physician-specified therapeutic agents such as embolization materials and of diagnostic materials such as contrast media.

Device Description

The Tip-shape Echelon Micro Catheter is an endhole, single-lumen catheter designed to be introduced over a steerable guidewire into the vasculature. The proximal end of the catheter incorporates a standard luer adapter to facilitate the attachment of accessories. The catheter has a semi-rigid proximal shaft which transitions into the flexible distal shaft to facilitate the advancement of the catheter in the anatomy. Dual radiopaque markers at the distal end facilitate fluoroscopic visualization. The outer surface of the catheter is coated to increase lubricity.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device, the Tip-Shape Echelon™ Micro Catheter. This is a submission for substantial equivalence to existing predicate devices, not typically a submission that would include a detailed study with acceptance criteria and AI performance metrics as these are more common for novel algorithms or AI/ML-driven devices.

Based on the provided information, I can extract the following:

1. A table of acceptance criteria and the reported device performance

The document lists "Testing" that was performed, which includes various in-vitro performance tests and biocompatibility verification. However, it does not explicitly state specific acceptance criteria (e.g., "Tip Tensile Strength > X N") or directly report quantitative device performance against these criteria. It only lists the types of tests conducted and concludes that biocompatibility was "verified."

Acceptance Criteria (Implicit from "Testing" section)Reported Device Performance
Dimensional and Visual AnalysisN/A (Not explicitly stated)
Tip Tensile StrengthN/A (Not explicitly stated)
Pressure TestingN/A (Not explicitly stated)
Guidewire FrictionN/A (Not explicitly stated)
Coil FrictionN/A (Not explicitly stated)
Tip Reshape-ability and RetentionN/A (Not explicitly stated)
Tip offset distances measurementN/A (Not explicitly stated)
Tip length measurement specificationN/A (Not explicitly stated)
Biocompatibility (in accordance with ISO 10993-1)Confirmed biocompatibility

2. Sample sizes used for the test set and the data provenance

The document does not mention sample sizes for any of the in-vitro performance tests. Data provenance is not applicable as this concerns physical device testing, not data generated by a test set.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This is a submission for a physical medical catheter, not an AI/ML device requiring expert ground truth for image analysis or similar tasks.

4. Adjudication method for the test set

Not applicable, as this is related to expert consensus on ground truth, which is not relevant to this device submission.

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-driven tool and therefore no MRMC study involving AI assistance would be performed or reported here.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This device is a physical catheter, not an algorithm.

7. The type of ground truth used

For the in-vitro performance tests, the "ground truth" would be the engineering specifications and tolerances for the device's physical properties. For biocompatibility, the ground truth is established by the results of tests conducted according to ISO 10993-1. These are physical measurements and biological assays, not expert consensus or diagnostic outcomes in the typical sense.

8. The sample size for the training set

Not applicable. There is no training set mentioned, as this is a physical device, not an AI/ML model.

9. How the ground truth for the training set was established

Not applicable, as there is no training set.

Dear Ms. Pourazar:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.

{2}------------------------------------------------

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); 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. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4648.
