LacertaMatrix™:A Flexible Wound Matrix for Clinical Use
LacertaMatrix™:
A Flexible Wound Matrix for Clinical Use
LacertaMatrix™ is a single use, non-pyrogenic, flexible, and conformable wound matrix made from alligator-derived hyaluronic acid (HA) and porcine gelatin.1
The Science
Benefits of American Alligator Hyaluronic Acid (HA)
American Alligator Hyaluronic Acid (HA) is considered beneficial, especially for wound healing, because it can enhance the body’s natural repair process by supporting cell infiltration, hydration, and in promoting tissue regeneration by reducing inflammation in chronic wounds2,3,4,5
Tissue Repair & Regeneration
Studies have shown that HA is crucial for wound healing, supporting cell infiltration (like skin cells), collagen deposition, and blood vessel formation (angiogenesis)2,3,4,5
Cellular Communication
HA has shown to interact with cell surface receptors (like CD44) to influence cell proliferation, differentiation, and immune responses, controlling inflammation.6,7
Modulates Inflammation
HA can form protective “cables” that bind inflammatory cells, preventing excessive tissue damage during immune responses.6,7
Size Matters
Different molecular sizes of HA (high vs. low weight) have distinct roles, with large HA supporting structure and smaller fragments potentially triggering repair, a complex balance.8,9

Application
LacertaMatrix™: Application Highlights
Size Selection
Select a device size slightly larger than the wound. LacertaMatrix™ may be applied as a whole sheet or trimmed to contact wound margins.
Preparation & Handling
Inspect the packaging to ensure it is intact and undamaged. Using aseptic technique, remove the device from the double-pouch configuration.
Placement & Conformity
For best results, ensure LacertaMatrix™ conforms to the underlying wound bed and is placed in maximum contact with healthy, well-vascularized tissue.
Resorption Over Time
LacertaMatrix™ resorbs into the wound over time, typically over a period of approximately two weeks.
Secondary Dressing
Protect LacertaMatrix™ using an appropriate secondary dressing based on wound characteristics and clinician preference.
Ongoing Care
Change the secondary dressing as needed to maintain a moist, clean wound area and allow wound inspection.
