The gathering and recovery of cells and cellular material from the mucosa in the esophagus for cytological and histological analyses.
The EsophaCap® Swallowable Cellular Retrieval Device is a non-sterile, non-endoscopic, singleuse Esophageal cell sampling device. The EsophaCap® is composed of an open-cell polyether polyurethane foam sphere attached to a polyester tether cap. The open-cell foam sphere ranging in diameter sizes from 20 mm to 35mm is compressed and encapsulated within a vegetable (hypromellose (HPMC)) capsule. When swallowed the EsophaCap® capsule dissolves releasing the foam sphere. The foam sphere expands to form a cytology and cellular retrieval device that allows a circumferential "bottle brush" collection using the expanded "open cell" foam sphere. The radiopaque polyester tether/stylus is used to slowly withdraw the foam sphere through the esophagus and then to subsequently retrieve the foam sphere with the cellular sample.
The provided text describes the EsophaCap® Swallowable Cellular Retrieval Device, its intended use, and its equivalence to predicate devices, but it does not contain information about acceptance criteria and a study proving the device meets those criteria from an AI/ML perspective. The document focuses on regulatory clearance (510(k)) based on substantial equivalence to existing devices.
The "Testing Performance Data" section mentions "bench testing, biocompatibility testing and user input" and lists specific bench tests like "dissolution testing, and tether /stylus tensile testing, and tether/stylus length test." These are engineering and material performance tests, not clinical studies demonstrating performance against diagnostic or other clinical acceptance criteria that would typically be associated with an AI/ML device.
Therefore, I cannot provide the requested information, specifically:
- A table of acceptance criteria and the reported device performance.
- Sample size used for the test set and data provenance.
- Number of experts used to establish ground truth and their qualifications.
- Adjudication method for the test set.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done.
- If a standalone (algorithm only) performance was done.
- The type of ground truth used.
- The sample size for the training set.
- How the ground truth for the training set was established.
This device, as described, is a physical medical device (cellular retrieval device), not an AI/ML diagnostic or predictive tool, and thus the typical metrics and study designs for AI/ML devices are not applicable or reported in this document.

Dear Martin von Dyck:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
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
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

{4}------------------------------------------------
Indications for Use:
The gathering and recovery of cells and cellular material from the mucosa in the esophagus for cytological and histological analyses.
Technological Characteristics of the Subject Device Compared to the Predicate Devices:
The EsophaCap® Swallowable Cellular Retrieval Device is substantially equivalent to the legally marketed predicate Cell-Mate™ Mass Cytology Cellular Retrieval System cleared under K934193. The substantial equivalence is in terms of intended use/indications of use, target patient population, anatomical locations, method of operation, operating instructions, and single use.
The technological differences are that this subject device is:
- a. non-sterile, while the predicate device is provided sterile;
- b. there is a change in the dissolvable capsule material from animal based gelatin to a vegetable capsule;
- shelf-life (for the 10 pore per inch foam sphere); ﻥ
- d. an additional foam porosity has been added;
- an additional smaller foam sphere diameter; e.
- f. a smaller capsule has been added;
- the tether cap location has been moved g.
- the tether/stylus was shortened; h.
- i. the labeling/IFU have been updated to reflect the preceding changes.
The EsophaCap® Swallowable Cellular Retrieval Device is also substantially equivalent to the legally marketed Cytosponge™ Cell Collection Device cleared under K142695, K152794, and K181020. The substantial equivalence is in terms of intended use/indications of use, anatomical locations, method of operation, operating instructions, single use, non-sterile, foam porosity, and vegetable capsule.
Testing Performance Data:
The EsophaCap® Swallowable Cellular Retrieval Device performance testing consisted of bench testing, biocompatibility testing and user input. The bench testing included: dissolution testing, and tether /stylus tensile testing, and tether/stylus length test.
Conclusion:
CapNostics LLC, considers the EsophaCap® Swallowable Cellular Retrieval Device to be substantially equivalent to the legally marketed predicates: Cell-Mate™ Mass Cytology Cellular Retrieval System (K934193) and Cytosponge™ Cell Collection Device ( K142695, K152794, and K181020). Based upon the results of performance testing the design modifications to the EsophaCap® Swallowable Cellular Retrieval Device raises no new safety and effectiveness questions.
§ 874.4710 Esophagoscope (flexible or rigid) and accessories.
(a)
Identification. An esophagoscope (flexible or rigid) and accessories is a tubular endoscopic device with any of a group of accessory devices which attach to the esophagoscope and is intended to examine or treat esophageal malfunction symptoms, esophageal or mediastinal disease, or to remove foreign bodies from the esophagus. When inserted, the device extends from the area of the hypopharynx to the stomach. It is typically used with a fiberoptic light source and carrier to provide illumination. The device is made of materials such as stainless steel or flexible plastic. This generic type of device includes the flexible foreign body claw, flexible biopsy forceps, rigid biopsy curette, flexible biopsy brush, rigid biopsy forceps and flexible biopsy curette, but excludes the fiberoptic light source and carrier.(b)
Classification. Class II.
