Cutaneous Healing into Porous Biomaterials Impedes Infection

Focus: 

To test the ability of a percutaneous catheter to resist infection

Anticipated Impact: 

Reduced morbidity and mortality in patients with skin-penetrating devices and commercialization of the novel device by a Washington-based company

Abstract: 

Percutaneous (skin-penetrating) devices such as vascular and dialysis catheters, glucose monitors, and artificial prostheses are essential for medical care. The use of these critical devices, however, is associated with high risk of infection leading to significant morbidity and mortality. The proposed work is a new approach that uses material into which the skin can heal, thus providing a barrier to microbial attachment and infection. The proposed work will test whether cutaneous integration into biomaterial inserted into the skin will resist bacterial challenge by Staphylococcus aureus, an organism that commonly infects percutaneous devices. The commercialization plan continues a fruitful collaboration with Healionics, a successful start-up biotech company that has licensed the technology from the University of Washington.
