The SeedNet Family is intended for cryogenic destruction of tissue during surgical procedures. The SeedNet Family is indicated for use as a cryosurgical tool in the fields of general surgery, dermatology, neurology (including cryoanalgesia), thoracic surgery, ENT, gynecology, oncology, proctology, and urology. The system is designed to destroy tissue by the application of extreme cold temperatures including prostate and kidney tissue, liver metastases, tumors, skin lesions, and warts.
The SeedNet Family has the following specific indications:
- I Urology (ablation of prostate tissue in cases of prostate cancer and Benign Prostate Hyperplasia "BPH")
- 트 Oncology (ablation of cancerous or malignant tissue and benign tumors, and palliative intervention).
- 트 Dermatology (ablation or freezing of skin cancers and other cutaneous disorders. Destruction of warts or lesions, angiomas, sebaceous hyperplasia, basal cell tumors of the eyelid or canthus area, ulcerated basal cell tumors, dermatofibromas small hemanglomas, mucocele cysts, multiple warts, plantar warts, actinic and seborrheic keratoses, cavernous hemanglomas, perianal condylomata, and palliation of tumors of the skin)
- . Gynecology (ablation of malignant neoplasia or benign dysplasia of the female genitalia)
- General surgery (palliation of tumors of the rectum, l hemorrhoids, anal fissures, pilonidal cysts, and recurrent cancerous lesions, ablation of breast fibroadenomas.)
- ENT (Palliation of tumors of the oral cavity and u ablation of leukoplakia of the mouth).
- . Thoracic surgery (ablation of arrhythmic cardiac tissue cancerous lesions)
- 트 Proctology (ablation of benign or malignant growths of the anus or rectum, and hemorrhoids)
The SeedNet Family may be used with a magnetic resonance imaging (MRI) device or an ultrasound device to provide real-time visualization of the cryosurgical procedure.

Acceptance Criteria and Device Performance for SeedNet Family Cryosurgical System
This document outlines the acceptance criteria and the study proving the SeedNet Family cryosurgical system meets these criteria, based on the provided 510(k) summary (K052530).
1. Table of Acceptance Criteria and Reported Device Performance
The 510(k) summary for the SeedNet Family (SeedNet/SeedNetGold System, CryoThera System, Cryo-Hit System) does not explicitly list distinct "acceptance criteria" in a quantitative or pass/fail format typical for performance studies of diagnostic devices. Instead, the submission focuses on demonstrating substantial equivalence to existing predicate devices (SeedNet Family, CryoCare CS system, and Visica system) for its expanded indications for use, particularly the addition of "ablation of breast fibroadenomas."
The "performance" is implicitly demonstrated through this claim of substantial equivalence. The core argument is that since the existing predicate devices are already cleared for the expanded indication and operate on similar principles, the SeedNet Family, with effectively identical technological characteristics and principles of operation, also meets the necessary performance for this expanded use.
Therefore, the "acceptance criteria" and "reported device performance" in this context are primarily qualitative and based on the established safety and effectiveness of the predicate devices for the specified indications.
| Acceptance Criterion (Implicit) | Reported Device Performance |
|---|---|
| Safety and Effectiveness for Cryogenic Destruction of Tissue: The device must safely and effectively destroy target tissue through cryoablation for the specified indications. | The SeedNet Family operates on the same principles of cryosurgery as the predicate devices. The predicate devices (CryoCare CS system and Visica system) are already cleared for the ablation of breast fibroadenomas, and the existing SeedNet Family is cleared for a wide range of cryosurgical applications. |
| Technological Characteristics: The device's technological characteristics (software, user interface, principles of operation) must be substantially equivalent to predicate devices. | The submission explicitly states: "All systems are cryo-surgery systems, which employ similar performance characteristics. In all other aspects including technological characteristics, software, user interface and principles of operation, the SeedNet Family described in this submission is substantially equivalent to the cleared SeedNet Family." |
| Expanded Indication for Ablation of Breast Fibroadenomas: The device must be suitable for this specific procedure. | This indication is already claimed by the 510(k)-cleared CryoCare CS system and Visica system, establishing a precedent for its safety and effectiveness using similar cryo-surgery technology. |
| No New Questions of Safety and/or Effectiveness: The device, with its expanded indications, should not introduce any new safety or effectiveness concerns compared to predicate devices. | The submission explicitly states: "Galil Medical Ltd. believes that the SeedNet Family described in this submission is substantially equivalent to the combination of its predicate devices... and does not raise any new questions of safety and/or effectiveness." |
2. Sample Size Used for the Test Set and Data Provenance
The 510(k) summary does not describe a specific clinical "test set" or a new clinical study with a defined sample size for the expanded indication of breast fibroadenomas. The approach taken is substantial equivalence based on previously cleared devices.
Therefore, there is no direct information provided regarding:
- Sample size used for the test set: Not applicable as no new clinical test set was conducted for this specific submission to demonstrate performance against explicit acceptance criteria.
- Data provenance (country of origin, retrospective/prospective): Not applicable as the submission relies on the existing clearance and presumed data supporting the predicate devices, rather than new data.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
Since no new clinical test set was conducted for this 510(k) submission, there is no information provided regarding:
- Number of experts used to establish ground truth: Not applicable.
- Qualifications of those experts: Not applicable.
4. Adjudication Method for the Test Set
As no specific test set was used for this expanded indication, there is no adjudication method provided.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not performed or reported in this 510(k) submission. The submission is focused on substantial equivalence to predicate devices, not on comparing performance with and without AI assistance or human readers. The device described is a cryosurgical unit, a therapeutic device, not a diagnostic AI tool that would typically involve MRMC studies.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
A standalone performance study for an algorithm was not performed or reported. The SeedNet Family is a hardware-based cryosurgical system, not an AI algorithm. While it may be used with visualization tools (MRI or ultrasound), the core device itself is not a standalone algorithm requiring such a study.
7. Type of Ground Truth Used
The ground truth for the expanded indication, by virtue of substantial equivalence, would be based on the established clinical outcomes and effectiveness of the predicate devices for breast fibroadenoma ablation, which would involve:
- Pathology: Confirmation of successful tissue destruction or removal.
- Imaging: Evidence from MRI or ultrasound that the target tissue was ablated as intended.
- Clinical Outcomes Data: Patient follow-up to assess the success of the treatment and absence of recurrence.
However, these are inferences based on the nature of the device and its intended use, not explicitly stated as "ground truth used" for a new study within this 510(k) summary.
8. Sample Size for the Training Set
The concept of a "training set" is relevant for machine learning algorithms. The SeedNet Family is a hardware-based cryosurgical unit, not an AI or machine learning device. Therefore, a training set is not applicable, and no sample size for a training set is provided.
9. How the Ground Truth for the Training Set Was Established
Since there is no training set for an AI algorithm, the question of how its ground truth was established is not applicable.
