The first patenting from 4M Biotech Inc. describes a wound dressing with incorporated color-changing pH sensors that are continuously responsive to the pH of wounds or wound exudate.
A laboratory technique used to generate pluripotent stem cells from any tissue, cellular reprogramming, has led a group of researchers to the discovery of a process that could have an impact on natural tissue repair.
Authors of a multi-center study welcomed results from a device that works with a smartphone or tablet to capture medical images for a more detailed understanding of infected wounds. By capturing heat produced by a wound and using bacterial fluorescence, the Swift Ray 1 developed by Swift Medical Inc., may help clinicians tell the difference between inflammation and a potentially dangerous infection.
Stimlabs LLC has taken a new view of wound healing by developing a fenestrated dehydrated complete human placental membrane allograft for chronic and acute wounds. The fenestration in the Release product allows fluids to drain away from the wound, promoting faster healing, while the tissue provides protection.
The $1.83 million grant Fesarius Therapeutics Inc. was recently awarded will allow the company to work on the next generation of dermal repair products to treat complex wounds. The funds from the National Institutes of Health (NIH) will go towards further development of the company’s advanced dermal regeneration scaffold for reconstructive surgery and takes the total amount of non-dilutive grant funding Fesarius has received to develop its hydrogel technology, Dermisphere, to $4 million.
Cresilon Inc. obtained U.S. FDA clearance for a hemostatic gel that staunches the flow of blood from minor external wounds. The Cresilon hemostatic gel (CHG) is the first technology to blend polymers from the algae plant to instantaneously create a mechanical barrier against bleeding.
Coloplast A/S agreed to acquire wound care company Kerecis Ehf for up to $1.3 billion in a bid to strengthen its presence in the high-growth, U.S.-centric biologics segment. Kerecis has developed a technology which uses intact fish skin from Atlantic cod to treat chronic wounds. It has around 5% share of the U.S. biologics market.
Saturating bioactive glass with silver sustains the metal’s antimicrobial properties and reduces biofilm formation, researchers at the University of Birmingham, U.K., found. Their study, published in Biofilm, demonstrated that specific preparation, storage and application techniques minimize the transformation of silver ions to silver chloride that typically reduces silver’s healing properties over time.
Ra Medical Systems Inc. launched a simple device that holds sutures more securely in place for closure of percutaneous wound sites during cardiac electrophysiology, structural heart and vascular surgical procedures.
Researchers at Indiana University School of Medicine are exploring avenues to heal wounds by identifying proteins that are active in fetuses, but largely inactive in adults and absent in diabetic adults. They have identified a protein called nonselenocysteine-containing phospholipid hydroperoxide glutathione peroxidase, or NPGPx, that fits the bill and could be the basis for therapies aimed at diabetic wound healing. NPGPx is a direct transcriptional target of miR-29. miR-29 is downregulated in fetal tissue, thus NPGPx is active in fetal tissue but becomes mostly inactive in the skin after birth.
