The SOMAVAC™ Device is a portable battery powered vacuum source / waste container intended for the removal of surgical and bodily fluids from a closed wound following plastic surgery and other general surgery forming large flaps for hematoma and seroma prophylaxis. It is intended for use in homecare and healthcare environments.
The single-patient use SOMAVAC™ Device is capable of generating sustained vacuum at the end two surgical drains to effectively remove bodily fluids after plastic or general surgeries. The SOMAVAC™ Device has a battery-powered SOMAVAC™ Pump assembly to generate vacuum with accessories, including disposable collection units, two drain connectors, and one belt. All products are non-sterile. Surgical drains are not included. The SOMAVAC™ device is compatible with non-collapsible, open channel (proximal), smooth bore drains with a distal inner diameter of 3mm - 4.5mm (commonly 15 – 19 Fr.). Up to two drains can be attached to the SOMAVAC™ Device. Each disposable waste collection units collects up to 100 mL of fluid. Versions of the device will be marketed with factory-set single, vacuum pressure levels ranging from 60 to 350mmHg. The device maintains suction throughout its use in a manner analogous to a thermostat by selectively running the pump motors to maintain the preset pressure. The device stops when the collection units are full or if the collection units are detached from the device. SOMAVAC™ Pump assembly has light and sound indicators to help users identify when the collection unit is full and ready to be exchanged, the battery is ready to be changed, or if there is a malfunction.
The SOMAVAC™ Device, a portable battery-powered vacuum source/waste container for surgical and bodily fluid removal, underwent non-clinical testing to demonstrate substantial equivalence to its predicate devices.

Anesthesia Conduction Catheter and Apparatus Suction
Class II (21 CFR 868.5120) and Class I (21 CFR 878.4680
ReLeaf catheters are indicated for use where a routine drainage tube is required to drain fluids and exudates during or after surgery. The additional lumens allow for application of anesthetic to relieve postoperative pain.
The ReLeaf catheter is comprised of a radiopaque multi-lumen catheter which bifurcates proximally into a single lumen wound drain line and a single lumen anesthetic infusion line. The distal tip of the device is composed of a thin film with one side for anesthetic infusion and the other for wound drainage. The anesthetic infusion and drainage sides of the catheter are clearly marked and mid-shaft depth markings are also present. Proximally the infusion and drain lines are both affixed to an insertion trocar.
The provided FDA 510(k) summary for the ReLeaf™ Catheter focuses on demonstrating substantial equivalence to a predicate device (Axiom Multipurpose Wound Drain, K993592) through bench-top and animal testing. It does not contain information about a study involving human readers, AI assistance, or the specifics of ground truth for a test set in the context of diagnostic accuracy. This is a medical device approval for a physical catheter, not a diagnostic imaging or AI-driven decision support system.
Therefore, many of the requested categories in your prompt are not applicable to the provided document.
However, based on the information provided, here's what can be extracted and inferred within the context of a medical device submission focused on substantial equivalence:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria for this type of device are generally qualitative (meets standards, no new safety/effectiveness issues) and demonstrate performance comparable to the predicate. The "reported device performance" are the results of various bench and animal tests.
Acceptance Criteria Category | Specific Criteria | Reported Device Performance |
---|---|---|
Safety & Effectiveness | No new issues of safety or effectiveness introduced compared to predicate. | Performance testing results support a substantial equivalence determination. |
Biocompatibility | Compliance with ISO 10993 standards. | Full battery of ISO 10993 testing passed. |
Material Performance | Materials suitable for intended use; no impact on safety/effectiveness due to different materials/coatings. | Materials and coatings did not impact safety or effectiveness. |
Design Performance | Distal tip design difference does not impact safety/effectiveness; performance confirmed for intended use. | Performance of the ReLeaf catheter confirmed for its intended use in bench testing and simulated use animal testing. |
Mechanical Performance | (Implied) Device should function as intended without failure. | Performance testing included insertion force, removal force, leak testing, patency, lumen compression, fatigue strength, tensile strength, tissue adherence. (Results are not explicitly quantified in this summary, but implied to be acceptable). |
Leachables | (Implied) No harmful substances leaching from the polymer. | Polymer leachables testing performed. (Implied acceptable results). |
Simulated Use | Device performs as expected in a simulated environment. | Simulated use animal testing conducted. (Implied acceptable results). |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size: Not applicable. The "test set" here refers to the actual devices subjected to bench and animal testing. The document does not specify the number of catheters tested for each bench test or the number of animals used.
- Data Provenance: Bench-top testing and simulated use animal testing. No country of origin is specified for the animal testing, but the submission is to the U.S. FDA. The data is prospective as it was generated specifically for this 510(k) submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- This concept is not applicable as this is a physical medical device. "Ground truth" for device performance is established through objective measurements in laboratory and animal testing, not expert interpretation of diagnostic data.
4. Adjudication Method for the Test Set
- Not applicable. Adjudication methods like 2+1 or 3+1 are used for human expert review of diagnostic cases, not for assessing the physical performance of a catheter.
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 a medical device for anesthesia and drainage, not an AI-assisted diagnostic tool. No human reader studies comparing AI vs. no AI assistance were conducted or are relevant for this type of device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. There is no algorithm or AI component in the ReLeaf™ Catheter.
7. The Type of Ground Truth Used

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document refers to various standard biocompatibility tests (e.g., Rabbit Pyrogen Test, Hemolysis-Rabbit Blood, Salmonella typhimurium REVERSE Mutation ASSAY, Kligman Maximization Study, USP CLASS VI, Elution Test, USP MUSCLE IMPLANTATION STUDY IN RABBITS WITH HISTOPATHOLOGY). The sample sizes are inherent to the standard protocols for these specific biological tests (e.g., number of rabbits for pyrogenicity or implantation, number of wells/bacteria for mutagenesis). The document does not explicitly state the specific number of samples or animals used beyond what is implied by the test names.
Data provenance (country of origin, retrospective/prospective) is not mentioned, as these are lab-based biological tests, not clinical studies involving patient data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. This submission concerns biocompatibility and dimensional equivalence, not diagnostic performance or expert review of medical images/data. The "ground truth" here is established by the validated methods of the specified biological and physical tests and their established pass/fail criteria.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods like 2+1 or 3+1 are typically used for resolving disagreements in expert readings of medical data. The tests described are objective biological and physical assessments.
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 a submission for an AI/CAD device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not a submission for an AI/CAD device.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
The "ground truth" for the tests performed is based on:
- Established Biomedical Standards: For tests like USP CLASS VI, the ground truth is defined by the requirements outlined in the United States Pharmacopeia.
- Standardized Laboratory Protocols: For tests like pyrogenicity, hemolysis, mutagenesis, and sensitization, the ground truth is determined by the specific, validated methods and endpoints of these universally accepted in vitro and in vivo biological assays.
- Physical Measurement Comparisons: For dimensional equivalence, the ground truth is direct measurement and comparison to the predicate device's specifications.
8. The sample size for the training set
Not applicable. There is no AI/machine learning model being developed, so no training set is relevant.
9. How the ground truth for the training set was established
Not applicable. As there is no AI/machine learning model, there is no training set and therefore no ground truth establishment for it.
