The Electrosurgical Probes are disposable electrosurgical devices intended to be used in general surgical procedures where electro-coagulation and cutting of soft tissues is desired. They are intended to be used with ORATEC Interventions ElectroThermal™ Generators.

The ORATEC Interventions Electrosurgical Probes are single-use electrosurgical devices designed for use in minimally invasive procedures where electro-coagulation and cutting of soft tissues is desired. They are designed to provide minimally invasive access to the targeted tissue, and to deliver radio-frequency energy in a controlled fashion. The modified probes consist of the following features:

• a shaft with a radiofrequency-energized tip for minimally invasive access to . perform tissue coagulation and/or cutting;
• different electrode tip configurations to provide optimal access to tissue; .
• . handle and cable connection receptacle at the proximal end.

The modifications made from the predicate device are:

• Adding alternate electrode tip materials; .
• Adding alternate insulating materials on the probe shaft; .
• Adding different tip configurations; .
• Decreasing handle, probe shaft, and electrode dimensions for the smaller versions. ●

The provided text is a 510(k) Summary for a device modification, specifically for ORATEC TAC-S Monopolar Cautery Probe. This type of submission focuses on demonstrating substantial equivalence to a previously cleared predicate device, rather than proving safety and efficacy through new performance studies akin to those for a novel device or software.

Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving a device meets those criteria in the context of, for example, an AI/ML algorithm or a new medical device's clinical performance.

Here's why and what information is provided:

• Focus of a 510(k) for device modification: The primary goal of this Special 510(k) is to show that the modified device (ORATEC Electrosurgical Probes with altered materials, tip configurations, and dimensions) is as safe and effective as the existing, legally marketed predicate device (Electrosurgical Probes, K965007). It achieves this by highlighting similarities and explaining how differences do not raise new questions of safety or effectiveness.
• Nature of the device: This is an electrosurgical device, not an AI/ML system. Performance is typically assessed through engineering design verification and validation, biocompatibility, electrical safety, electromagnetic compatibility, and potentially bench testing to confirm physical properties and functionality.
• Lack of AI-specific or clinical study details: The document does not describe:
  • Acceptance criteria for AI performance (e.g., sensitivity, specificity, AUC).
  • Any study explicitly designed to "prove" the device meets such criteria using patient data, ground truth established by experts, or MRMC studies.

Based on the provided text, I cannot complete the table or answer most of the questions as they pertain to clinical performance studies, AI/ML models, or specific ground truth methodologies.

However, I can extract information relevant to the device modification and its comparison to the predicate:

Answers to Applicable Questions (based only on the provided text):

1. A table of acceptance criteria and the reported device performance: Not applicable in the traditional sense for a 510(k) device modification. The acceptance criteria essentially boil down to demonstrating "substantial equivalence" to the predicate device, meaning the modifications do not raise new questions of safety or effectiveness. The "performance" is implicitly deemed equivalent if substantial equivalence is established. No specific quantitative performance metrics (like accuracy, sensitivity) are presented for this type of device modification.
2. Sample size used for the test set and the data provenance: Not applicable. No clinical or comparative test set data from patients is described. The "test" for a device modification in a 510(k) is typically a review of engineering changes, material specifications, and comparison to the predicate.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No ground truth establishment for a test set of patient data is described.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
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. This is not an AI device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable.
8. The sample size for the training set: Not applicable. No training set is mentioned as this is not an AI/ML device.
9. How the ground truth for the training set was established: Not applicable.

In summary, this document is a regulatory submission for a device modification of an electrosurgical probe, demonstrating substantial equivalence to a predicate. It does not contain the detailed performance study information typically requested for AI/ML devices or novel medical devices requiring extensive clinical data.

The Deflectable Electrosurgical Probes are disposable, monopolar electrosurgical devices intended for general surgical use in procedures where electro-coagulation and cutting of soft tissues is desired. They are designed to be used with ORATEC ElectroThermal generators.

The Deflectable Electrosurgical Probes are disposable, monopolar electrosurgical devices designed to coagulate or to cut tissues. They provide minimally invasive access to the targeted tissues. The Deflectable Electrosurgical Probes are used in conjunction with ORATEC ElectroThermal generators to deliver monopolar radiofrequency (RF) energy for electro-coagulation and cutting of soft tissues. The Deflectable Electrosurgical Probes incorporate: A shaft with an RF energized tip to perform tissue coagulation; Optional tip configurations for various general tissue coagulation and cutting uses; A controllable, deflectable tip at the distal end of the probe to allow easier access to all tissue surfaces; A handle, with cable connector and deflecting mechanism at the proximal end.

The provided text is a 510(k) summary for the ORATEC Deflectable Electrosurgical Probes, which explicitly states that it is a summary of safety and effectiveness information. The document focuses on demonstrating substantial equivalence to a predicate device, rather than presenting a performance study with acceptance criteria and a detailed analysis of device performance.

Therefore, the information required to answer your request (acceptance criteria, specific study details, sample sizes, expert qualifications, etc.) is not present in the provided text. The document's purpose is to facilitate regulatory clearance by showing similarity to an already approved device, not to detail the results of a primary performance study against explicit acceptance criteria.

The key points from the document are:

• Device: ORATEC® Interventions, Inc., Deflectable Electrosurgical Probes
• Intended Use: Disposable electrosurgical devices for general surgical use in procedures where electro-coagulation and cutting of soft tissues is desired. Used with ORATEC ElectroThermal generators.
• Predicate Device: ORATEC® Interventions, Inc., Electrosurgical Probes, K965007
• Basis for Clearance: Substantial Equivalence to the predicate device. The document explicitly states: "Based on the information presented here, the ORATEC Interventions Inc., Deflectable Electrosurgical Probes are substantially equivalent to the Electrosurgical Probes manufactured and distributed by Oratec Interventions, Inc."

Since no performance study with acceptance criteria is described, I cannot fill out the requested table or address the specific questions about sample sizes, experts, ground truth, or MRMC studies.

Isolated Electrosurgical Probe/Device-Salinetrode

The provided document is a 510(k) clearance letter from the FDA for an electrosurgical device (Salinetrode™) from February 1998. It primarily addresses the regulatory status (substantial equivalence) of the device to previously marketed predicate devices.

This type of document (a 510(k) clearance letter) does not contain the detailed technical study information you are asking for.

Specifically, a 510(k) clearance letter:

• Does not include acceptance criteria for device performance. It confirms that the device is "substantially equivalent" to a predicate device, meaning it has the same intended use and technological characteristics, or different characteristics that do not raise new questions of safety and effectiveness.
• Does not include specific study data, sample sizes, expert qualifications, or ground truth methodologies. These details would be found in the 510(k) submission itself, which is typically a much more extensive document that includes performance data, bench testing, and potentially clinical studies, depending on the device and its risk profile.
• Does not discuss multi-reader multi-case (MRMC) studies or standalone algorithm performance, as this device is a physical electrosurgical probe, not an AI/software device.

Therefore, I cannot provide the requested information based on the input text. The document only confirms the device's regulatory clearance based on substantial equivalence, not its specific performance metrics or the studies backing them up.
