The Multi4 System is intended for use by trained urologists for endoscopically controlled tissue resection and coagulation, and removal of bladder tumors (TURBT) via suction channel under controlled flow conditions following resection using a monopolar resectoscope. The Multi4 System is also intended to deliver injectable materials into the urinary bladder wall during transurethral endoscopic procedures.

The Multi4 System is an electrosurgical system used during urethral resection procedures of adult patients. The system, intended to remove and collect tissue from the bladder, includes a single-use electrosurgical instrument, known as the Multi4 B, as well as the reuseable Multi4 Pump. The Multi4 Pump administers energy from an external electrosurgical unit to the handheld Multi4 B instrument, which has electrosurgical functions and allows for fluid transport and tissue sample collection. The Multi4 B instrument accesses the bladder through the working channel of a commercially available cystoscope. The Multi4 System is a prescription device intended for use in professional healthcare facilities by healthcare professionals (HCPs).

The Multi4 System consists of the following components:
• Multi4 Pump (with Integrated Fluid Control)
o Footswitch
• Multi4 B
o Resectoscope & Needle
o Simple4tainer (For collection of gross resected tissue pieces for pathology)

The provided FDA 510(k) clearance letter and summary for the Multi4 System primarily focuses on demonstrating substantial equivalence to predicate devices through design similarity, material composition, intended use, and technological characteristics. The document details extensive non-clinical testing performed to ensure safety and effectiveness.

However, the provided text does not contain details about acceptance criteria, the study design, or performance metrics in a way that allows for the construction of a table comparing acceptance criteria with reported data, nor does it provide information on sample sizes for test sets, data provenance, expert involvement for ground truth, adjudication methods, MRMC studies, or standalone algorithm performance.

The document does mention:

• Non-Clinical Testing: Software Verification and Validation Testing, Sterility Testing, Packaging Testing, Shelf-life Testing, Biocompatibility Testing (Cytotoxicity, Irritation, Sensitization, Acute Systemic Toxicity, Pyrogenicity), Electrical Safety & EMC (IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, and IEC 60601-2-2), Integrity Testing, Functional Testing (Cut and coagulation, aspiration, irrigation, injection), Dimensional Inspection and Testing, Simulated Use Testing.
• Lack of Clinical Study: The "SUMMARY OF NON-CLINICAL TESTING" section and the overall context strongly suggest that the clearance was based on non-clinical data demonstrating equivalence to predicate devices, rather than a clinical study evaluating specific performance metrics against acceptance criteria for a new AI/algorithm. There is no mention of "ground truth" as it would apply to an AI study (e.g., expert consensus, pathology, outcomes data).

Therefore, I must state that the requested information regarding acceptance criteria, study data for AI performance, sample sizes for AI test/training sets, expert roles, adjudication, and MRMC studies is not present in the provided text. The document focuses on demonstrating substantial equivalence via engineering and bench testing, not clinical performance or AI/algorithm validation with a test set and ground truth in the manner typically required for AI-driven devices.

Without this specific information from the provided text, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria in the context of an AI-driven device with performance metrics.

If this were an AI device, the missing information would be crucial for understanding its validation. For this specific device and the information provided, the "acceptance criteria" were met by demonstrating that the Multi4 System performs as safely and effectively as its predicate devices through rigorous non-clinical testing.

The Rezūm System is intended to relieve symptoms, obstructions, and reduce prostate tissue associated with benign prostatic hyperplasia(BPH). It is indicated for men ≥ 50 years of age with a prostate volume 30 cm³ ≤ 150 cm³. The Rezūm System is also indicated for treatment of prostate with hyperplasia of the central zone and/or a median lobe.

The Rezūm System is designed to treat patients with bothersome urinary symptoms associated with benign prostatic hyperplasia (BPH). The Rezūm System utilizes radiofrequency current to generate "wet" thermal energy in the form of water vapor, which is then injected into the transition zone and/or median lobe of the prostate tissue in controlled 9-second doses. The vapor that is injected into the prostate tissue rapidly disperses through the interstitial space between the tissue cells. As the vapor cools, it condenses immediately on contact with tissue and the stored thermal energy is released, denaturing the cell membranes and causing cell death.

The denatured cells are absorbed by the body, which reduces the volume of prostate tissue adjacent to the urethra. The vapor condensation process also causes a rapid collapse of vasculature in the treatment zone, resulting in a bloodless procedure.

Following thermal therapy for BPH, small pieces of coagulated tissue may slough off and be expelled via urination. This sloughing process may continue for a few months post-procedure depending on the rate of healing.

The Rezūm System consists of the following:
• Rezūm Generator – reusable, non-sterile capital equipment, provided with one power cord
• Rezūm Delivery Device Kit – sterile, single-use kit containing the following disposable components:

• One sterile Delivery Device with cable and tubing
• One sterile syringe
• One sterile spike adaptor
• One sterile water vial

The provided FDA 510(k) clearance letter and summary for the Rezūm System (K250584) focuses on an expanded indication for use, specifically for larger prostate volumes, rather than establishing acceptance criteria for a new device's performance. The information provided describes studies demonstrating the comparable safety and effectiveness of the device for this expanded range, rather than defining specific performance metrics against pre-defined acceptance criteria for a novel device.

Since the document is for an expanded indication and not a de novo clearance, the acceptance criteria are implicitly that the device performs similarly in safety and effectiveness in the expanded patient population as it did in the previously cleared population. The study's goal was to demonstrate this similarity.

Here's an analysis based on the provided text, outlining what can and cannot be extracted regarding acceptance criteria and performance data:

Acceptance Criteria and Device Performance

The concept of "acceptance criteria" in this context is less about a numerical threshold for a novel device's performance (e.g., sensitivity > X%, accuracy > Y%) and more about demonstrating that the device's safety and efficacy profile remains acceptable and comparable within the expanded patient population.

Implicit Acceptance Criteria:

• Safety: No new or unexpected adverse events in patients with prostate volumes >80 cm³ and ≤150 cm³. The rates of adverse events, including serious complications, should be generally similar to those observed in patients with prostate volumes ≤80 cm³.
• Effectiveness: Significant and similar improvements in functional and quality of life outcomes in patients with prostate volumes >80 cm³ and ≤150 cm³ compared to patients with prostate volumes ≤80 cm³. No negative impact on sexual function.

Reported Device Performance (as demonstrated by the supporting studies):

• Safety: "Patients with prostate volumes >80 cm³ had generally similar rates of adverse events, including serious complications. No unexpected adverse events were reported, and all adverse events were consistent with those reported in the Rezūm System pivotal clinical study."
• Effectiveness: "Significant and similar improvements in functional and quality of life outcomes were demonstrated in both patient populations, with no negative impact to sexual function."

Table of (Implicit) Acceptance Criteria and Reported Device Performance:

Study Details:

The document describes two types of clinical evidence used to support the expanded indication:

1. Systematic review and meta-analysis of clinical studies: This reviewed existing data on the Rezūm System for patients with prostate volumes >80 cm³ and compared outcomes to patients with prostate volumes ≤80 cm³.
2. Manufacturer-sponsored prospective, non-randomized, single-arm study: This study specifically evaluated the safety and effectiveness of the Rezūm System in patients with prostate volumes >80 cm³ and ≤150 cm³. The results were compared to data from the Rezūm System's original "pivotal clinical study."

Based on the provided text, here's what can be answered for each point:

1. Sample size used for the test set and the data provenance:

   • Systematic Review/Meta-analysis: The text does not specify the exact sample size. It states it was a "systematic review and meta-analysis of clinical studies," implying a pooling of data from multiple studies. The data provenance (country of origin, retrospective/prospective) is not specified for the individual studies included in the meta-analysis, but they are existing clinical studies.
   • Manufacturer-sponsored study: The text does not specify the exact sample size. It describes the study as "prospective, non-randomized, single-arm." It evaluates patients with prostate volumes >80 cm³ and ≤150 cm³. Data provenance is primarily domestic, as it's a manufacturer-sponsored study submitted to the FDA. It is prospective.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
   The Rezūm System is a therapeutic device (for relieving symptoms and reducing prostate tissue), not a diagnostic algorithm. Therefore, "ground truth" in the typical sense of expert label annotations for images or diagnostic classifications is not directly applicable here. The outcomes (symptom relief, prostate tissue reduction, adverse events, quality of life, sexual function) are assessed directly from patient reports, objective measurements (e.g., prostate volume changes), and clinical evaluations by treating physicians. The text does not mention a specific "ground truth" panel of experts, nor would it typically be required for a therapeutic device study focused on clinical outcomes.

3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
   Not applicable (N/A). As a therapeutic device focusing on direct clinical outcomes, adjudication methods like those used for diagnostic algorithms (e.g., for image interpretation) are not described or typically relevant in this context. Clinical events and outcomes are recorded based on predefined criteria, and adverse events are typically reported and classified by investigators and reviewed by safety committees.

4. 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 (N/A). This is a therapeutic device, not an AI-powered diagnostic tool. Therefore, a multi-reader multi-case study comparing human readers with and without AI assistance is not relevant to this submission.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
   Not applicable (N/A). This is a therapeutic medical device, not an algorithm. The Rezūm System is a physical device used in a procedure performed by a human clinician.

6. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
   As explained in point 3, the concept of "ground truth" for a therapeutic device is different. For this submission, the "ground truth" and evidence of effectiveness and safety comes from:

   • Clinical Outcomes Data: Patient-reported symptoms, quality of life scores, measures of sexual function, and potentially objective measures like post-treatment prostate volume.
   • Adverse Event Reporting: Documentation and classification of adverse events.
   • Comparison to a Pivotal Clinical Study: The study for the expanded indication compared its outcomes to those established in the device's original pivotal clinical study.

7. The sample size for the training set:
   Not applicable (N/A). This is a therapeutic medical device; there is no "training set" in the context of machine learning or AI algorithms. The development of the device itself would have involved engineering, preclinical, and early human studies, but these are not referred to as a "training set."

8. How the ground truth for the training set was established:
   Not applicable (N/A), as there is no "training set" in the AI/ML context for this device.

The SpydrBlade Flex Instrument is indicated for use in the cutting (incision, dissection, avulsion) of soft tissue using radiofrequency energy and the coagulation (hemostasis, cauterization, arrest of bleeding) of soft tissue using microwave energy in the gastrointestinal tract as required or encountered in endoscopic procedures.

The CROMA Electrosurgical Generator is intended to provide Radiofrequency (RF) and microwave (MW) energy for cutting, coagulation, and ablation of soft tissue, when used in conjunction with compatible electrosurgical instruments and accessories.
The Creo Medical Electrosurgical System is not intended for use in cardiac procedures.

The Creo Medical electrosurgical system comprises of the CROMA electrosurgical generator, an interface cable accessory and a footswitch accessory, and a compatible electrosurgical instrument.

The CROMA electrosurgical generator comprises two distinct energy sources for the independent generation of bipolar radiofrequency (RF) current at 400 kHz and microwave (MW) current at 5.8 GHz.
Both energy sources are delivered through the same output coaxial connector. These generator outputs are controlled in terms of voltage, power, current, duty cycle, and duration by means of widely used and long-established design and engineering techniques. Via these controls and system design, only one energy source can be delivered to the output coaxial connector at any one time.

The compatible electrosurgical instrument that is subject of this submission is SpydrBlade Flex. The subject and predicate devices use the same electrosurgical generator, footswitch, and interface cable.

SpydrBlade Flex is a single-use, sterile endoscopic electrosurgical instrument used for procedures in the gastrointestinal (GI) tract. The product is sterilized using Ethylene Oxide.
SpydrBlade Flex is intended for use in endoscopes with a minimum working channel of 3.2 mm and maximum working length of 1.35 m.

SpydrBlade Flex incorporates a distal tip, a shaft, and a handle. The distal tip includes a jaws assembly that consists of two gold-plated ceramic bipolar antennas, each soldered to a stainless-steel base. The stainless-steel bases are joined in a manner to provide a mechanical opening and closing function. The bipolar antennas deliver RF energy for cutting and MW energy for coagulation, in the same manner as the predicate Speedboat SB1. The cutting and coagulation functions are performed regardless of the jaw mechanism and can be provided with the jaws open or closed. The jaw mechanism provides a grasping function for easier tissue manipulation between and during energy applications.

The subject and predicate devices are composed of the same technological components with the same principles of operation related to the energy function:

• Cutting of mucosa, sub-mucosa, muscle using bipolar RF energy,
• Thermal coagulation of mucosa and/or sub-mucosa, muscle, vascular and arterial structures using MW energy.

The provided FDA 510(k) clearance letter pertains to the SpydrBlade Flex Instrument (PRD-RG1-001), an endoscopic electrosurgical unit and accessories. However, the document does not contain information related to software-based AI performance, multi-reader multi-case (MRMC) studies, or the establishment of ground truth by expert consensus for diagnostic purposes.

The information requested in the prompt, such as acceptance criteria based on diagnostic performance metrics (e.g., sensitivity, specificity, AUC), sample size for test sets, number and qualifications of experts for ground truth, adjudication methods, and training set details, are typically associated with the clearance of AI-powered diagnostic devices.

The SpydrBlade Flex Instrument, as described in this 510(k) summary, is a surgical instrument that uses RF and MW energy for cutting and coagulation of soft tissue. The "Software Verification and Validation" section likely refers to the embedded software controlling the electrosurgical generator and instrument functions, ensuring its proper operation and safety, rather than an AI analyzing medical images or data for diagnostic purposes.

Therefore, I cannot provide a table of acceptance criteria and reported device performance for AI, nor can I elaborate on sample sizes, ground truth establishment, or human-in-the-loop performance studies, as this information is not present in the provided document for this specific device.

The document primarily focuses on:

• Substantial Equivalence: Comparing the SpydrBlade Flex Instrument to a predicate device (Speedboat Flush SB1 Instrument) based on indications for use, technological characteristics (design, materials, principles of operation), and safety/performance testing.
• Non-Clinical Testing: Sterilization, biocompatibility, electrical safety, microwave safety, electromagnetic compatibility, and software verification/validation.
• Bench Tests: Confirming that the device meets design verification and validation criteria and performs equivalently to the predicate device.

Key takeaway for your request: This document describes the clearance of a medical device (an electrosurgical instrument) that does not appear to involve AI for diagnostic purposes, hence the absence of the detailed AI-related study information you are seeking.

It is available in various working lengths.

The provided FDA 510(k) clearance letter for ClearHemograsper is for an endoscopic electrosurgical unit and accessories, which is a physical medical device, not an AI/software as a medical device (SaMD). Therefore, the provided text does not contain information on acceptance criteria, test sets, ground truth establishment, or clinical studies typically associated with the evaluation of AI models.

The information requested in the prompt (acceptance criteria, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, training set details) is specific to the validation of AI/SaMD, particularly for diagnostic or prognostic purposes where ground truth and human reader performance are critical.

Since the ClearHemograsper is a physical device used for cauterizing and coagulation, its performance is evaluated through bench testing (e.g., dimension, rotatable performance, pushability, actuation, tensile strength, output value, hemostatic performance, short circuit, catheter tube temperature tests), biocompatibility studies, sterilization validation, shelf-life studies, and electrical safety/EMC testing. Clinical studies were not considered for this submission (as stated on Page 10, Section 13).

Therefore, I cannot fulfill your request for:

• A table of acceptance criteria and reported device performance related to AI/SaMD metrics.
• Sample sizes, data provenance, expert numbers, adjudication, MRMC studies, standalone performance, or ground truth establishment methods for an AI test set.

The document describes the device's technical specifications and comparisons to a predicate device, focusing on physical and electrical performance, and safety standards for a mechanical/electrical medical device.
