HTx Disposable Hysteroscope System
HTx Disposable Hysteroscope System is intended to be used for viewing of the cervical canal and uterine cavity for the purpose of performing diagnostic and operative procedures.
Note: Hysteroscopes are used as tools for access to the uterine cavity and are not, in and of themselves a method of surgery.
The HTx Disposable Hysteroscope System is a single use hysteroscope endoscope intended for gynecology procedure applications. It includes a single-use, disposable hysteroscope cannula (HTx40 or HTx60), a reusable imaging system (HTx1000/Htx2000), and optional accessories (medical keyboard, barcode reader and IV pole mounting rack). The disposable hysteroscope contains a miniature CMOS camera, a light-emitting diode (LED) illumination module, and channels for fluid in/out flow as well as for instrument insertion. HTx60 has a cannula outer diameter of 6.2 mm and adapts to tools up to 3 mm (9 Fr), while HTx40 has an outer diameter of 4.5 mm and adapts to tools up to 5 Fr. The cannula connects directly to the image processor via an image cable. The image processor processes the raw image signal from the cannula and outputs the video on a display for real-time visualization. The image processor includes input/output ports for interfacing with different peripherals such as a keyboard or a USB flash disk. Fluid irrigation is achieved through a tube which is connected to an IV bag and pressured via peristaltic pump (not included in the subject device). The fluid inflow channel shares the same with the working channel.
The provided text is a 510(k) Premarket Notification for a general medical device (HTx Disposable Hysteroscope System), not an AI/ML-driven device. Therefore, the document does not contain the specific information required to describe acceptance criteria and associated studies for AI/ML performance, such as:
- A table of acceptance criteria and reported device performance for AI metrics (e.g., sensitivity, specificity, AUC). The document focuses on general device performance characteristics.
- Sample size used for the test set and data provenance.
- Number of experts and their qualifications for establishing ground truth.
- Adjudication method for ground truth.
- MRMC comparative effectiveness study, effect size.
- Standalone (algorithm only) performance.
- Type of ground truth (expert consensus, pathology, outcomes data).
- Sample size for the training set.
- How ground truth for the training set was established.
The document primarily addresses the substantial equivalence of a new version of a hysteroscope system (HTx2000 image processor) to a previously cleared predicate device (HTx1000). The "non-clinical performance testing" section on page 12 refers to:
- Bench-top tests: Color performance (spectrophotometer measurements, working distance, color contrast enhancement) for the HTx2000.
- Basic electrical safety: IEC 60601-1:2005+AMD1:2012.
- Electromagnetic compatibility (EMC): IEC 60601-1-2:2020.
- Software testing: Validated as "Basic Documentation Level" according to FDA guidance (which is about software documentation for any medical device with software, not specific to AI/ML performance).
- Battery safety: IEC 62133-2:2017/AMD1:2021 and UN38.3.
These tests are standard for general medical device clearance and do not involve the specific types of performance studies or acceptance criteria associated with AI/ML functionality (e.g., diagnostic accuracy, clinical classification, or segmentation performance).
In conclusion, based on the provided text, it is not possible to describe the acceptance criteria and study proving device performance in the context of an AI/ML device, as the submission does not pertain to such a device.

HTx Disposable Hysteroscope System
HTx disposable hysteroscope system is intended to be used for viewing of the cervical canal and uterine cavity for the purpose of performing diagnostic and operative procedures.
The HTx Disposable Hysteroscope System is a single use hysteroscope endoscope intended for gynecology procedure applications. It includes a disposable cannula module, a reusable imaging system, a medical grade display and optional software for processing patient management. The disposable cannula contains a miniature complementary metal-oxide-semiconductor (CMOS) camera, a light-emitting diode (LED) illumination module, and a channel for fluid and device. The cannula connects directly to the image system via an image cable. The cannula also contains three (3) buttons for video recording, picture taking, and light-emitting diode (LED) brightness control. The image system connects to a medical grade display module via DVI port. The external patient management software runs on an external PC that connects with the image system via LAN cable.
This document is a 510(k) premarket notification for the AcuVu HTx Disposable Hysteroscope System, indicating that the device is a Class II medical device. The document primarily focuses on demonstrating substantial equivalence to a predicate device (AcuVu GDT-1000, K180096) rather than detailing a clinical study with specific acceptance criteria and performance metrics for an AI-powered device.
Therefore, many of the requested categories for AI-specific studies are not applicable or cannot be extracted from this document, as the HTx Disposable Hysteroscope System, as described, does not appear to be an AI-powered device in the sense of an algorithm for diagnostic or prognostic purposes. It is a traditional medical imaging device (hysteroscope) for viewing the cervical canal and uterine cavity.
Here's an attempt to answer the questions based on the provided text, acknowledging the limitations:
1. A table of acceptance criteria and the reported device performance
The document does not provide a table of acceptance criteria with numerical performance metrics for a diagnostic or AI algorithm. Instead, it lists various non-clinical tests performed to ensure the device meets safety and functional requirements. The "acceptance criteria" can be inferred as compliance with the listed standards and demonstrating acceptable results in the tests.
| Acceptance Criteria Category | Standard/Requirement | Reported Device Performance |
|---|---|---|
| Sterilization | ISO 11135:2014 (Ethylene Oxide Sterilization) | Validation performed in accordance with ISO 11135:2014. (Implies successful sterilization and packaging) |
| Biocompatibility | FDA guidance "Use of International Standard ISO 10993-1," "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". Specific tests: Cytotoxicity (ISO 10993-5:2009), Sensitization (ISO 10993-10:2010), Irritation (ISO 10993-10:2010), Acute Systemic Toxicity (ISO 10993-11:2017), Material Mediated Pyrogenicity (ISO 10993-11:2017). | Results demonstrated the subject device is non-cytotoxic, non-sensitizing, non-irritating, not systemically toxic, and non-pyrogenetic. |
