The Veloxion System is intended for use by trained urologists for endoscopically controlled tissue chip resection and coagulation, and removal of prostate adenomas and bladder tumors (TURBT) via suction channel under continuous flow conditions following resection using a bipolar resectoscope.

The Veloxion System consists of the following components:

• Veloxion Controller (with Integrated Fluid Control)
  • Footswitch
• Veloxion Resectoscope
• Veloxion Fluid Control Set
• Veloxion Video Control Unit
• Veloxion Roll Stand

The Veloxion System also includes the following Class I accessories for handling of waste collected from the patient (these items only handle waste after it is already outside the patient), which includes:

• Waste Management Tubing: To provide a conduit for transfer of aspirated fluids and tissue from the patient and from under the patient's buttocks drape
• Tissue Catch: For collection of gross resected tissue pieces for pathology.
• Waste Management Bags: To provide bags for final collection of outflow.

The Veloxion System provides bipolar resection and coagulation of intrauterine tissue, it distends the uterus by filling with saline, it provides pressure control of the intrauterine cavity for insufflation to facilitate viewing with the integrated hysteroscope and it monitors the fluid deficit (potential fluid absorbed by the patient's body) to the physician established limit. The components of Veloxion System perform the following functions:

• The Veloxion Controller provides bipolar radiofrequency outputs (for cut and coagulation) and fluid/pressure control through the use of two integrated peristaltic pumps, provides the user interface to establish the desired set pressure, monitors intracavitary pressure using dual independent pressure sensors mechanically connected to the Veloxion Fluid Control Set irrigation lumen. The software then monitors, controls and notifies the user when the limits are reached or when specific conditions are met.
• The Veloxion Resectoscope is a sterile single use hand held bipolar radiofrequency device configured to provide camera and light for visualization of the anatomy for the resection of tissue and aspiration of resected chips. Fluid inflow and aspiration of the resected chips are controlled by the Controller's peristaltic pumps.
• The Veloxion Fluid Control Set is a sterile single use device that provides conduits for fluid inflow, aspiration of resected tissue and fluids and a diaphragm (pressure membrane) that provides mechanism for the Controller to measure cavity pressure (through the irrigation lumen) during the procedure thereby facilitating the insufflation function.
• The Veloxion Video Control Unit provide control of the camera, light, display image to a commercially available monitor, stores image and video selected by the user from a session, and provides a USB connection for a USB Stick download of stored media by the user.
• The Veloxion Roll Stand enables monitoring of saline remaining in the saline bag and facilitates the fluid deficit function.

This document, a 510(k) Premarket Notification for the Veloxion System, details the device's characteristics and its equivalence to previously cleared predicate devices, allowing it to be marketed. However, it explicitly states, "No new performance testing was required to establish substantially equivalence. Results of tests in reviewed as part of clearance of K190099 and K162979 with comparison testing to the predicates (predicate Veloxion System and Richard Wolf Resectoscope) support substantial equivalence to the identified predicates."

This crucial statement means the provided text does not contain the acceptance criteria or a study that proves the device meets the acceptance criteria directly within this submission. It relies on previous clearances (K190099 and K162979) and their associated testing.

Therefore, many of the requested details about acceptance criteria, specific performance data, sample sizes, ground truth establishment, and expert involvement are not present in this document.

Despite this, I will extract what information is available and clearly indicate where details are missing based on the document's content.

Based on the provided document, specific details regarding the acceptance criteria and a standalone study proving the device meets these criteria are NOT presented. The submission relies on demonstrating substantial equivalence to predicate devices, referencing prior clearances (K190099 and K162979) for performance data.

Here's an analysis of the requested information based on the provided text, highlighting what is present and what is absent:

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

• Not provided in this document. The document states "No new performance testing was required" for this submission, indicating that performance data relies on previous clearances of the Veloxion System (K190099, K162979) and comparative testing against other predicates. This document does not present a table of acceptance criteria or new reported performance data.

2. Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Not provided in this document. No new test set is described.

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/Not provided in this document. As no new test set or ground truth establishment is described for this submission, this information is not available. This would typically be relevant for studies involving diagnostic or image-based AI, which this device is not.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable/Not provided in this document. No test set or human adjudication process is described for this 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/Not provided in this document. This device is a surgical system, not an AI-assisted diagnostic tool. Therefore, an MRMC study is not relevant in this context, and no such study is mentioned.

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

• Not applicable/Not provided in this document. The Veloxion System is a physical medical device (resectoscope system), not a standalone algorithm or AI. Its performance is tied to its mechanical and electronic functions.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• Not applicable/Not provided in this document. For a physical device like the Veloxion System, "ground truth" would typically relate to engineering specifications, performance parameters (e.g., fluid flow rates, power output, pressure control accuracy), and safety standards, rather than clinical diagnostic "ground truth" established by experts or pathology. This document does not detail the specific performance testing or the "ground truth" metrics used in prior clearances.

8. The sample size for the training set

• Not applicable/Not provided in this document. The Veloxion System is a hardware device with integrated software for control and monitoring. While software verification testing is mentioned (point below), there's no indication of a "training set" in the context of machine learning.

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

• Not applicable/Not provided in this document. As above, no "training set" in the machine learning sense is described. The document mentions "Software Verification Testing was performed using the same protocol reviewed as part of K 190099 for all steps affected by the change and documentation updated per FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices."" This indicates adherence to software validation best practices, but not a machine learning training paradigm.

Summary of what the document does provide:

• Device Name: Veloxion System
• Predicate Devices: K190099, K162979 (both Corinth MedTech, Inc. Veloxion System), K062720, K042523 (Richard Wolf Medical Instruments Corporation systems).
• Indications for Use: The Veloxion System is intended for use by trained urologists for endoscopically controlled tissue chip resection and coagulation, and removal of prostate adenomas and bladder tumors (TURBT) via suction channel under continuous flow conditions following resection using a bipolar resectoscope.
• Technological Characteristics Comparison: A detailed table comparing the subject device's energy type, RF functions, cavity pressure monitoring, irrigation fluid, outer sheath dimensions, electrode extension, and electrode movement to its predicates. Minor differences are noted.
• Performance Data Statement: "No new performance testing was required to establish substantially equivalence. Results of tests in reviewed as part of clearance of K190099 and K162979 with comparison testing to the predicates (predicate Veloxion System and Richard Wolf Resectoscope) support substantial equivalence to the identified predicates."
• Software Verification: Mentions software verification testing was performed using the same protocol as K190099, updated per FDA guidance for software in medical devices.

In essence, this 510(k) submission is a "Special 510(k)" which often means a modification to an already cleared device, and thus relies on demonstration of substantial equivalence rather than entirely new performance studies. The detailed studies proving acceptance criteria were conducted for the original clearances (K190099 and K162979).
