NEOX®FLO Wound Matrix



Neox®Flo can be prepared by the physician as a suspension with normal saline for topical application or applied in dry form topically. It is especially useful in difficult to reach wounds that are either irregularly shaped or tunneled. The typical chronic wound patient will receive an average of 1-2 applications of Neox®Flo to facilitate healing. The dosage depends on the wound size.


Regulated under PHS 361 [21 CFR 1270 & 1271]: Human cells, tissues, and cellular and tissue-based products. Creates a unified registration and listing system for establishments that manufacture HCT/Ps and establishes donor eligibility, current good tissue practice, and other procedures to prevent the introduction, transmission, and spread of communicable diseases by HCT/Ps. Among other criteria, HCT/Ps are required to be minimally manipulated and intended for homologous use. Homologous use means the repair, reconstruction, replacement, or supplementation of a recipient’s cells or tissues with an HCT/P that performs the same basic function or functions in the recipient as in the donor. [1]  In the case of amniotic membranes, homologous use include serving as a selective barrier, protection and covering of a wound.  Micronization may also be considered more than minimally manipulated by the FDA.
