This document is a 510(k) summary for the Mercator MedSystems Bullfrog Micro-Infusion Device.

Based on the provided information, no new performance testing was conducted to support substantial equivalence for the current submission (K161402). The document explicitly states: "No new performance testing was conducted to support substantial equivalence, since the predicate and subject devices are identical in terms of technological characteristics."

Therefore, the requested information about acceptance criteria and reported device performance from a new study proving the device meets those criteria for the K161402 submission cannot be extracted from this document because no such new study was performed.

However, the document mentions that performance testing of the predicate device (K153501) was conducted. This predicate device is also the "Bullfrog Micro-Infusion Device" by Mercator MedSystems, implying the subject device is identical to its predicate in design and performance, except for an update in the Indications for Use.

The document states that the predicate device's performance testing included:

• Mechanical and fluid delivery performance
• Biocompatibility
• Sterilization validation
• In-vivo safety and effectiveness studies

It further notes: "All tests met the pre-determined specifications and acceptance criteria."

Since no new study directly addressing acceptance criteria for K161402 is provided, I cannot populate the table or answer the specific questions (2-9) about a study from this application. The information provided pertains to the predicate device's testing, for which details like specific acceptance criteria, sample sizes, expert qualifications, and ground truth methodologies are not included in this 510(k) summary.

A compliant stabilizing balloon inflates with the actuator to provide a force opposite the needle tip for proper seating of the needle is retracted within the sheathing structure by vacuuming the hydraulic actuator.

Here's an analysis of the provided text regarding the acceptance criteria and study for the Bullfrog Micro-Infusion Device, based only on the input you provided.

Note: The provided document is a 510(k) summary for a medical device. These summaries typically highlight that performance tests were done and met criteria, but they do not usually contain the detailed acceptance criteria or the full study results that would be found in a complete test report or clinical study report. Therefore, much of the requested information (especially specific numerical acceptance criteria, detailed study parameters, and specific quantitative results) is not present in this document.

While the document states that performance testing, biocompatibility, sterilization validation, and in-vivo safety and effectiveness studies were conducted and all tests met pre-determined specifications and acceptance criteria, it does not provide the specific acceptance criteria or the detailed results of these studies. It also explicitly states "N/A" for "Indications for Use" under a section heading, which is likely a formatting error as it also lists indications for use earlier in the document.

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample sizes used for any specific test sets (e.g., for mechanical, fluid delivery, or in-vivo studies). It also does not specify the country of origin of the data or whether the studies were retrospective or prospective. It only mentions "in-vivo safety and effectiveness studies" without details.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the document. The document describes a medical device, and the "ground truth" concept as usually applied to AI algorithms (e.g., expert consensus on images) is not applicable or detailed here. For device performance, the "ground truth" would typically be defined by the physical or biological reality measured during testing against defined specifications.

4. Adjudication Method for the Test Set

This information is not provided in the document.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

No MRMC comparative effectiveness study is mentioned for the Bullfrog Micro-Infusion Device. This type of study is typically associated with diagnostic imaging or AI algorithms, not directly with a physical interventional medical device as described here.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

The Bullfrog Micro-Infusion Device is a physical interventional medical device, not an algorithm. Therefore, "standalone algorithm performance" is not applicable in this context.

7. The Type of Ground Truth Used

For a physical device, the "ground truth" is established through engineering specifications, physical measurements, chemical analyses (biocompatibility), and biological outcomes (in-vivo studies, safety/effectiveness). The document generally states that tests met "pre-determined specifications and acceptance criteria," which implies that these specifications serve as the "ground truth" against which performance was measured. No specific mention of expert consensus, pathology, or outcomes data as a distinct ground truth source (like in imaging studies) is given for the device's technical performance.

8. The Sample Size for the Training Set

This information is not applicable. The Bullfrog Micro-Infusion Device is a physical medical device, not an AI algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable, as it is a physical device and not an AI algorithm.
