The device description explicitly states that the EchoMark and EchoMark LP are "implantable ultrasound-visible markers" comprised of a polymeric material. This indicates a physical, hardware-based device, 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 "for radiographic marking of sites in soft tissue" and "for situations where a soft tissue site needs to be marked for future medical procedures." This describes a device used in vivo (within the body) to mark a location for imaging or future intervention.
- Device Description: The device is described as "implantable ultrasound-visible markers." This confirms it is placed inside the body.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections. This device does not perform any such testing on samples.
The device is an implantable medical device used for marking purposes, not for diagnosing conditions based on in vitro analysis.

Predicate Device: K152070, BioZorb LP Marker Reference Device: K112267, Polyganics Neurolac Nerve Guide
Substantially Equivalent to:
The EchoMark and EchoMark LP are substantially equivalent in intended use, principle of operation and technological characteristics to the BioZorb LP Marker cleared under premarket notification K152070.
Description of the Device Subject to Premarket Notification:
The EchoMark and EchoMark LP are implantable ultrasound-visible markers used to facilitate visualization of a soft tissue site. The EchoMark and EchoMark LP are
4
comprised of 70:30 poly(L-lactide-co-caprolactone) (PLC) which resorbs completely in one year or more. The EchoMark LP (low profile) is identical but smaller in size than the EchoMark. Both have identical performance and technological characteristics. The EchoMark and EchoMark LP are provided sterile and are single use devices. The EchoMark material is entirely polymeric and therefore has no clinically relevant diamagnetic or ferromagnetic potential. This device is MR safe.
Indications for Use:
The EchoMark and EchoMark LP are indicated for radiographic marking of sites in soft tissue. In addition, the EchoMark and EchoMark LP are indicated for situations where a soft tissue site needs to be marked for future medical procedures.
Technical Characteristics Compared to Predicate Device:
The proposed predicate device for the EchoMark and EchoMark LP is the BioZorb LP Marker (K152070) manufactured by Focal Therapeutics. Sonavex has identified BioZorb LP as the predicate device because the devices share the same indications for use and identical or similar technological characteristics including principles of operation, compatibility with ultrasound, device size, polymeric materials, bioabsorption time and sterilization method.
Sonavex also used a reference device to support the material of the EchoMark and EchoMark LP which allows FDA to evaluate the proposed scientific methods for assessing this type of device material in a similar anatomic space (in addition to ISO 10993 biocompatibility testing). The reference device also shares certain technological similarities. The Neurolac Nerve Guide (Polyganics BV; K112267) is made from poly(lactide-co-caprolactone), which is the same material as the EchoMark and EchoMark LP. The Neurolac is also of similar size and is placed in surgical sites.
The EchoMark and EchoMark LP are indicated for radiographic marking of sites in soft tissue. The BioZorb LP Marker is also indicated for radiographic marking of sites in soft tissue. The EchoMark and EchoMark LP and the BioZorb LP are indicated for situations where the soft tissue site needs to be marked for future medical procedures. The markers are each positioned into a treatment site during a procedure and serve as passive imaging contrasts to the surrounding tissue for the purposes for radiographic visualization of the site at a later timepoint.
The BioZorb LP Marker and EchoMark LP are designed to mark treatment sites in soft tissue, which typically contains some combination of muscle, fat, fascia, and vessels. Anatomical treatment sites are identical.
The difference in indications for use between the EchoMark/EchoMark LP and BioZorb LP predicate does not constitute indications that create a new intended use. The EchoMark and EchoMark LP have the same intended use.
Technological characteristics between the EchoMark/EchoMark LP and the BioZorb LP are similar with some differences which were addressed with performance data. Differences include visualization compatibility as both the EchoMark LP and BioZorb LP Markers are radiographically visible markers composed of a bioabsorbable material, however, the BioZorb LP Marker also contains permanent titanium components that offer visibility under X-ray, CT, and MRI. The EchoMark/EchoMark LP
5
does not contain the titanium clips, and is intended to be visualized by ultrasound, a subset of the radiographic modalities available. Performance data was provided which evaluated this difference and found it did not impact substantial equivalence.
Both the EchoMark/EchoMark LP and the BioZorb LP Marker are low profile but there are differences in shape. Performance data was provided which addressed this difference and found that it did not impact substantial equivalence.
The EchoMark and EchoMark LP are radiographically visible markers composed solely of a bioabsorbable polymer: poly-lactide-co-caprolactone. The BioZorb LP Marker is a radiographically visible marker composed of a bioabsorbable poly-lactide polymer that has similar technological characteristics. The BioZorb LP Marker is made from the same lactide polymer without caprolactone. To establish equivalency of the device materials, a reference device, Polyganics' Neurolac Nerve Guide (K112267) was selected. The EchoMark/EchoMark LP and reference product, Neurolac Nerve Guide, are both made of poly-lactide-co-caprolactone.
The EchoMark/EchoMark LP and BioZorb LP Marker degrade within 1 year or more. Performance testing was completed to confirm bioabsorption time compared to the predicate device. The EchoMark LP is sterilized via ethylene oxide and BioZorb LP Marker is sterilized via gamma irradiation. Testing for ethylene oxide residuals has been performed and shows that residuals do not exceed acceptable limits.
The provided comparison of the specifications and associated device testing demonstrates the functional equivalence of the products. The differences discussed do not raise new issues of safety and effectiveness.
Therefore, the EchoMark and EchoMark LP are substantially equivalent to the predicate device.
Safety and Performance Data:
All necessary testing has been performed for the EchoMark and EchoMark LP to assure substantial equivalence to the predicate device and reference material and demonstrate that the device performs as intended.
The following ISO 10993 biocompatibility and safety testing was performed on the EchoMark device. Results from the tests indicate that the device is non-toxic, nonsensitizing, non-mutagenic and non-irritating therefore biocompatible for its intended use:
- Cytotoxicity
- Sensitization
- Irritation/ Intracutaneous Reactivity
- Acute Systemic Toxicity
- Pvrogenicitv
- Genotoxicity
- Subacute/Subchronic Toxicity with Histologic Evaluation to confirm Safety (GLP Swine Testing)

Performance testing, Bench: Successful completion of the following tests confirmed that risk controls were properly implemented, and design outputs meet design inputs and device is suitable for its intended use:
- ISO 11135 Sterility testing validated to SAL of 10-6
- ISO 11607-1 Packaging validation distribution simulation
- Bench Suturability and Suture Retention
- Labeling verification
- Geometric analysis of EchoMark and EchoMark LP ।
