No
The device description clearly states it is a "hydrophilic medical device which consists of resorbable dry gelatin foam" and is a physical object preloaded into a cartridge. It is a physical implantable material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "embolization of hypervascular tumors." This is a therapeutic procedure performed in vivo (within the body) to block blood vessels.
- Device Description: The device is a physical material (gelatin foam) designed to be injected into blood vessels to create a mechanical barrier.
- Mechanism of Action: It works by physically blocking blood flow, not by analyzing biological samples in vitro.
- Input Imaging Modality: Fluoroscopy is used to monitor the in vivo procedure.
- Anatomical Site: The vascular system is an in vivo anatomical site.
- Performance Studies: The performance studies involve in vivo animal studies to evaluate the embolic effect and safety within the body.
IVD devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
An animal study was conducted on seven test (Torpedo Gelatin Foam) and eight control (EmboCube Embolization Gelatin, K181021) adult female sheep in the renal arteries over a period of 4 weeks. The animal study evaluated vascular safety, local tissue effects, and in vivo degradation of the Torpedo Gelatin Foam. Angiography and/or histopathology confirmed that the Torpedo Gelatin Foam provided an embolic effect in renal arteries for at least four weeks. Normal flow of the renal arterial vasculature was never recovered in any animal at any time point. There was no significant difference for artery patency between any articles at any time point. All test animals had a necrotized renal tissue, indicative of successful embolization. The animals were clinically normal throughout the study duration.

Once rehydrated, the deformable torpedoes can be injected into the target vessel with an intravascular catheter or a micro-catheter (depending on the size range) to provide a mechanical barrier to blood flow. Contrast enhancement may be used to monitor the embolization procedure using fluoroscopy. The device is intended for single use and is provided sterile.
Torpedo Gelatin Foam is similar in design to the predicate device, EmboCube Embolization Gelatin (K181021), as both of them provide a mechanical barrier to blood flow in the vasculature and are delivered using catheters. The changes to the device are as follows: a) A variant of the gelatin cube device has been added to the range, b) A new packaging has been added, c) A blunt stylet has been included.
The subject device is available in two sizes, as the predicate device. The subject and predicate devices differ in shape. The predicate EmboCube Embolization Gelatin (K181021) has a cubic shape, whether dry or Comparison to hydrated. At the dry state, the subject Torpedo Gelatin Foam is compressed Predicate into a cylindrical shape. In the uncompressed / hydrated state, the subject Torpedo Gelatin Foam is a solid rectangle of the same section as the predicate (2.5 mm or 5.0 mm), only the length differs. Both the subject device and the predicate device, EmboCube Embolization Gelatin, K181021 are made wholly from the identical resorbable porcine qelatin.
The technological differences between the subject and predicate devices have been evaluated through biocompatibility, bench and animal testing to provide evidence of substantial equivalence of the Torpedo Gelatin Foam to the predicate device, EmboCube Embolization Gelatin (K181021).
No performance standards have been established under Section 514 of the Food, Drug and Cosmetic Act for these devices. However, vascular embolization devices are subiect to the special controls specified in "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices", issued on December 29, 2004. In addition, the subject device follows the FDA Draft Guidance on Medical Devices Containing Materials Derived from Animal Sources (Except for In Vitro Diagnostic Devices), issued on January 23, 2014.
A battery of tests performed on Torpedo Gelatin Foam were designed to demonstrate that the device meets critical design specifications as well as clinical performance attributes for its intended use. Where appropriate, the tests were based on the requirements of the following documents:
- FDA Guidance Class II Special Controls Guidance Document: Vascular ● and Neurovascular Embolization Devices (December 29, 2004)
- ASTM F2096-11, Standard Test Method for Detecting Gross Leaks in ● Medical Packaging by Internal Pressurization (Bubble Test)

Torepedo Gelatin Foam was evaluated for various performance attributes to demonstrate the substantial equivalence of the device to the predicate. The following is a list of all testing that was successfully completed:
- Macroscopic appearance (visual inspection) ●
- Compressed (dry) torpedo size ●
- Maximum swelling (hydrated size) ●
- Humidity (H₂0 analysis)
- Sterility
- Pvrogenicity (Bacterial endotoxins) ●
- Deliverability with a stylet ●
- Deliverability with catheters and radiopaque contrast agents
- . Flush test carried out on aged and sterilized subject devices
- Resorption .
- Embolic effect .
- . Comparative FTIR analysis for any foreign material transfer
Safety & Performance Tests (continued)
Biocompatibility testing was adopted from the predicate device EmboCube Embolization Gelatin, K181021. The only difference between the subject device and the legally marketed predicate device is that the subject device will be crimped and shaped into a torpedo. FTIR spectroscopy was performed in order to verify that there is no transfer of material from the crimper to the subject device. No further biocompatibility testing was required to qualify the subject device.
An animal study was conducted on seven test (Torpedo Gelatin Foam) and eight control (EmboCube Embolization Gelatin, K181021) adult female sheep in the renal arteries over a period of 4 weeks. The animal study evaluated vascular safety, local tissue effects, and in vivo degradation of the Torpedo Gelatin Foam. Angiography and/or histopathology confirmed that the Torpedo Gelatin Foam provided an embolic effect in renal arteries for at least four weeks. Normal flow of the renal arterial vasculature was never recovered in any animal at any time point. There was no significant difference for artery patency between any articles at any time point. All test animals had a necrotized renal tissue, indicative of successful embolization. The animals were clinically normal throughout the study duration.
The difference between the modified device and the cleared device. Biosphere EmboCube Embolization Gelatin [K181021] has raised no new issues.
