Oxtex, incorporated in May 2011, is a medical device company which has developed a novel autonomous controlled tissue expander for the use in reconstructive surgery based on technology developed originally at Oxford University.
Oxtex has secured its IP through several international patents to protect the know-how and design of its product, and these devices have several applications in a range of reconstructive and wound closure surgical procedures, restorative dentistry and veterinary surgery.
The Oxtex technology has been recognised by the business community; the company received the OBN awards for Best Emerging MedTech in late 2011 and best New Medical Product in 2012, the UK Enterprise Awards for Innovation in Tissue Expansion Solutions in 2018, and won the WOBA Owen Mumford Innovation Award 2019.
Oxtex addresses a significant challenge in reconstructive surgery, namely the absence of sufficient skin in the area where the surgery is taking place. However, skin has the remarkable ability to grow when put under controlled tension leading to the creation of additional skin and associated soft tissue. This is what the Oxtex device exploits. The device is implanted underneath the skin close to the repair site, where it will slowly expand in one direction causing the skin to grow. After the expander has been removed, this "new skin" can then be used in the reconstruction. More information on tissue expansion can be found here.
Oxtex has developed a self-inflatable tissue expander that enables the creation of additional skin through controlled stretching in a wide variety of anatomical locations. The expander has applications in many areas of plastic surgery (burns/scar revision, breast reconstruction, dental and oral surgery, crossbite correction), as well as the veterinary market (tumour removal). Successful tissue expansion reduces the cost of treatment and is a significant improvement to other alternative forms of surgical reconstruction.
