The Pajunk insufflation cannula acc. Veress and the modular insufflation cannula acc. Veress is employed in minimal invasive surgery. The cannula is designed for the initial puncture with subsequent gas insuffation for laparoscopic operations. It is used to establish a pneumoperitoneum.
The insufflation cannulae according Veress were developed especially for the safe and efficient r rio moumation oannalae and insufflation cannulae are equipped with maintenance free cocks and a female LuerLock connector. Before application, a sharp outer cannula (sterile packed for modular Veress, reusable for Standard Veress) is mounted onto the reusable inner cannula and fastened by means of a LuerLock connector. Therefore within the modular system , a new, absolutely sharp disposable outer cannula is used for every application. In comparison with totally disposable Veress-cannulae, with the same advantages, the modular system offers a large potential to reduce cost.
This is a premarket notification for a Veress and Modular Veress Insufflation Cannula. This type of submission typically focuses on demonstrating substantial equivalence to a predicate device rather than presenting extensive de novo clinical study data with specific acceptance criteria and detailed device performance metrics. Therefore, many of the requested data points (e.g., sample sizes for test and training sets, number of experts for ground truth, MRMC study details, acceptance criteria table) are not applicable or explicitly provided in this document.
Here's the information that can be extracted or inferred based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
This type of information is generally not included in 510(k) submissions for devices like the Veress cannula, which are often cleared based on substantial equivalence to predicate devices rather than meeting specific performance criteria in a new clinical study. The device's performance is assumed to be equivalent to the predicate devices.
2. Sample Size Used for the Test Set and Data Provenance
A formal "test set" in the context of a prospective clinical study with a defined sample size to prove performance against specific acceptance criteria is not described. The submission relies on substantial equivalence and "clinical evaluation and summarizing literature." Therefore, specific sample sizes for a 'test set' derived from a new study are not provided. The data provenance is described as "clinical evaluation and summarizing literature," suggesting a review of existing data rather than a new prospective study.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. The submission does not describe a new clinical study with a ground truth established by experts.
4. Adjudication Method for the Test Set
Not applicable. The submission does not describe a new clinical study with an adjudication process.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance
Not applicable. This device is a surgical instrument (insufflation cannula), not an AI-powered diagnostic or assistive tool. Therefore, an MRMC study and AI-related metrics are irrelevant.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
Not applicable. This device is a surgical instrument, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for the device's safety and effectiveness is primarily based on substantial equivalence to existing legally marketed predicate devices, which have a history of safe and effective use. Additionally, the submission mentions "clinical evaluation and summarizing literature," suggesting that the medical community's existing knowledge and published findings on similar devices serve as a form of "ground truth" regarding the general principles of Veress cannula use.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/ML device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. This is not an AI/ML device that requires a training set with established ground truth.
Summary of Device Rationale from the Submission:
The submission for the Veress and Modular Veress Insufflation Cannula focuses on demonstrating substantial equivalence to two predicate devices:
- Cannula with sharp obturator & Veress Needle by Karl Storz (K800668)
- Veress Cannula et al. by Richard Wolf Medical (K041321)
The rationale provided is that the proposed devices are "as safe and effective as and therefore substantial equivalent to the predicate devices" in terms of intended use, indication, and technical characterization. The document explicitly states: "The comparison between the predicate devices and the proposed devices... demonstrates that the proposed devices are safe and effective, as well as substantially equivalent to the predicate devices." It also mentions "The cannula system acc. Veress has been used for years now. The clinical evaluation and summarizing literature, which is part of this submission (10.0), makes this aspects evident." This implies that prior clinical experience and published data on this type of device support its safety and effectiveness without requiring a new, formal clinical trial with specific performance criteria.

Pajunk RFTL Radiofrequency needles are electrically insulated and may be used for percutaneous nerve blocks with local anesthetic solution or for radiofrequency lesioning.
Pajunk RFTL Radiofrequency needles are intended for coagulation of soft tissues, such as in long term pain treatment via neurosurgical lesioning procedures, as determined by professional neurosurgeon/ anesthetist and the instructions for use. These RF-cannulas are single use, sterile, non-pyrogenic and latex free medical devices. The RF-cannulas have bevel tips with an active area of 2 - 10 mm.
The needle puncture depth depends on the path chosen by the surgeon to reach and to eliminate the nerve bundle site. This required needle length is the patient contact part of the thermolesion needle. The nerve causing constant pain will be disrupted by utilizing the thermolesion heat radiating from the needle tip. Heat is generated by radio frequency and radiates only from the non-insulated needle tip. This limited heat radiation is used for focussed heat treatment depending on the surgeon's method of operation.
This document is a Premarket Notification Submission (510k) for the Pajunk Thermolesion Cannula "RFTL Radiofrequency Needle". A 510k submission primarily demonstrates substantial equivalence to a predicate device, rather than conducting a de novo study with acceptance criteria and performance reporting as might be expected for a novel device. Therefore, the information provided below will reflect the nature of a 510k submission.
Here is an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
For a 510(k) submission, the "acceptance criteria" are typically demonstrating substantial equivalence to a legally marketed predicate device. The performance is then judged on how well it matches or is considered equivalent to the predicate.
Acceptance Criteria (Demonstration of Substantial Equivalence) | Reported Device Performance (Summary of Equivalence) |
---|---|
Intended Use: Similar indications for use. | Pajunk RFTL Radiofrequency needles are intended for coagulation of soft tissues, such as in long term pain treatment via neurosurgical lesioning procedures. (Page 2) Also, the Pajunk RFTL Radiofrequency needles are electrically insulated and may be used for percutaneous nerve blocks with local anesthetic solution or for radiofrequency lesioning. (Page 4) |
Technological Characteristics: Similar design, materials, and operating principles. | The indications for use as well as the basic technological characteristics of Pajunk's RFTL cannulas are identical to Radionics thermo lesion needles K021942 manufactured by TOP. Coating, overall cannula length of deinsulated tip are substantially equivalent and as safe and effective as the predicate device's. (Page 2) Pajunk's RFTL cannulas have the same technological characteristics as the predicate device identified above. (Page 2) The NanoLine coating technique Pajunks cannulas are coated with is cleared for market in Pajunks NanoLine PMN K053283. (Page 2) |
Safety and Effectiveness: Demonstrate device is as safe and effective as the predicate. | Pajunk's single use anesthesia conduction needles for thermo lesion and neuro-stimulation are substantially equivalent in technique, specification, intended use, safety and effectiveness to the marketed predicate device listed above. (Page 2) The comparison between the predicate devices and the proposed devices demonstrates that the proposed devices are safe and effective, as well as substantially equivalent to the predicate devices. (Page 2) |
Sterilization: Equivalent sterilization methods. | The contract sterilizer and the sterilizing process... is the same as that used for Unipolar cannulas cleared for market by FDA under 510(k) number K000722 and Kit Products Pajunks Stimulong Set K043130, K033018 and Pajunks Plexolong Set K042979, K023218, K013041. (Page 2) |
Packaging: Equivalent packaging materials and procedures. | The packaging materials and procedures of Pajunk's RFTL cannulas are the same as those used for Unipolar cannulas cleared for market by FDA under 510(k) number K000722 and Kit Products Pajunks Stimulong Set K043130, K033018 and Pajunks Plexolong Set K042979, K023218, K013041. (Page 2) |
2. Sample Size Used for the Test Set and Data Provenance
This is a 510(k) submission focused on demonstrating substantial equivalence to predicate devices, not on a clinical study that would involve a "test set" in the traditional sense with patient data. Therefore, details regarding a specific sample size for a test set or data provenance (country of origin, retrospective/prospective) are not applicable to this document as no such study is described. The demonstration of equivalence relies on comparing technical characteristics and intended use, not on new clinical performance data from a dedicated test set.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
As explained above, no separate "test set" with ground truth established by experts is discussed in this 510(k) submission. Therefore, this information is not applicable. The "ground truth", in a broader sense for a 510(k), is the established safety and effectiveness of the predicate device.
4. Adjudication Method for the Test Set
Again, no "test set" or clinical study requiring an adjudication method is described in this 510(k) submission. This information is not applicable.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size
No MRMC comparative effectiveness study is mentioned or implied in this 510(k) submission. This information is not applicable. The submission focuses on device characteristics and equivalence, not on human reader performance with or without AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This device (a radiofrequency needle) is a physical medical instrument, not an algorithm or AI system. Therefore, the concept of a "standalone algorithm performance" is not applicable. Its use invariably involves a human neurosurgeon/anesthetist.
7. The Type of Ground Truth Used
For a 510(k) submission, the "ground truth" is typically the established safety and effectiveness of the legally marketed predicate devices. The new device aims to be substantially equivalent to this established standard. In this case, the predicate devices are "Radionics thermo lesion needles K021942" and "Stryker's RF cannulas K032406". The comparison also references other Pajunk devices previously cleared by FDA for sterilization and packaging equivalence (K000722, K043130, K033018, K042979, K023218, K013041, K053283).
8. The Sample Size for the Training Set
No "training set" in the context of an algorithm or AI development is mentioned in this document. This information is not applicable.
9. How the Ground Truth for the Training Set Was Established
As no "training set" or AI/algorithm development is described, the method for establishing its "ground truth" is not applicable.

The Pajunk EpiLong anesthesia conduction kit is indicated for administration of epidural anesthesia.
The Pajunk catheter is placed in the epidural space to facilitate a longer anesthetic effect. After the anesthesia conduction needle has been withdrawn from the patient, the catheter tip can remain in the epidural space for as long as determined by the professional anesthetist and the instructions for use (up to 72 hours).
The Pajunk Loss of Resistance (LOR)-Syringe is intended for use in conjunction with an epidural needle, to verify the needle tip placement in the epidural space by the Loss of Resistance technique as explained in standard medical textbooks. These syringes are not intended for injection or aspiration.
The Pajunk anesthesia conduction flat filter is a microporous filter used while administering to a patient injections of local anesthetics to minimize particulate (foreign material) contamination of the injected fluid.
The Pajunk Tuohy Borst Adaptor is connected to the needle via Luer connector. It ensures sealing and fixation of the catheter end and allows attachment of a Luer Lock syringe or infusion device.
Pajunk's EpiLong set is a single use, sterile, non-pyrogenic and latex free medical device kit. It is a epidural anesthesia kit consisting of a needle for insertion into the epidural space (a special Tuohy Cannula), a catheter for anesthesia administration to the epidural space, a flat filter as well as an adapter. After administration of immediate epidural anesthesia, the epidural catheter may be placed via the cannula into the epidural space. The cannula is then withdrawn, leaving the Epidural Catheter tip in the epidural space for as long as determined by the professional anesthetist and the instructions for use (up to 72 hours).
The provided document is a 510(k) Premarket Notification Submission for the EpiLong Anesthesia Conduction Kit. This type of submission focuses on demonstrating substantial equivalence to a previously legally marketed device (predicate device) rather than proving de novo safety and effectiveness through clinical trials with defined acceptance criteria and performance metrics.
Therefore, the document does not contain the information requested regarding acceptance criteria, study details, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, or training set specifics.
Instead, the submission states:
- Conclusion: "The comparison between the predicate device and the proposed devices in section 12 of this submission demonstrates that the proposed devices are safe and effective, as well as substantially equivalent to the predicate devices." (Page 1)
- FDA's finding: "We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices..." (Page 2)
In summary, there is no study described in this document that proves acceptance criteria are met, as the regulatory pathway chosen (510(k)) relies on substantial equivalence to a predicate device, not on meeting specific, pre-defined performance acceptance criteria through the types of studies typically associated with AI/software devices.
The document primarily focuses on:
- Device description and indications for use.
- Identification of predicate devices (BBrauns Perifix K813186).
- Mention of sterilization processes.
- A "detailed discussion of substantial equivalence" in a section (Section 12) that is not included in the provided text.
Without Section 12 or other detailed performance testing reports, it's impossible to extract the requested information.
