The grant will enable Sharklet Technologies to validate the effectiveness of a Sharklet-patterned catheter for inhibiting bacterial biofilm development of E. coli, a bacterial species commonly associated with catheter-associated urinary tract infections (CAUTIs). Further, Sharklet Technologies will prove feasibility of fabricating catheter-like prototypes that exhibit Sharklet-patterned surfaces. Upon successful conclusion of Phase I, a follow-on Phase II project will be designed to develop manufacturing methods for tube prototypes and demonstrate efficacy within an in vivo model. The company expects to complete both phases by mid-2011.

Dr. Shravanthi Reddy will serve as the principal investigator for the Sharklet catheter project. “We are pleased to have the opportunity to further develop a Sharklet Urinary Catheter as we believe the device holds the potential to significantly improve the quality of healthcare,” said Dr. Reddy. “As catheterassociated urinary tract infections are the most common of hospital-acquired infections, a major advance in catheter technology will enhance patient care and greatly improve hospital financials.”

Current methods for preventing bacterial UTIs introduce antimicrobial agents to reduce concentrations of bacteria associated with biofilm formation. The continued use of these antimicrobial agents leads to bacterial resistance patterns that make catheter infections more difficult to treat. Unlike current kill methodologies, the Sharklet catheter will be capable of sustained inhibition of bacterial biofilm through its unique pattern alone. Per findings from laboratory tests and early research, the Sharklet topography creates an energetically unstable surface that bacteria find inhospitable, rendering additional antibiotic coatings or treatments unnecessary.

Joe Bagan, chief executive officer of Sharklet Technologies said: “Our primary objective is to offer healthcare providers a new line of defense in infection control to significantly improve patient care and reduce the incidence of hospital-acquired infections while lowering overall costs.”

Sharklet is a microscopic pattern that is comprised of millions of tiny raised bars arranged in a specific diamond pattern. The pattern, which is inspired by the microbial inhibition qualities of shark skin, may be imprinted onto a film that may be applied via contact adhesive to existing surfaces in healthcare environments or manufactured onto the surfaces of medical devices to inhibit bacterial growth. The pattern creates an energetically unstable surface that microorganisms find inhospitable for growth. There is no chemistry, toxicity or leaching of any chemicals. In addition, Sharklet does not kill bacteria to control it and, as a result, the technology does not contribute to the serious and growing problem of bacterial resistance.

Sharklet is a developer of technologies that are designed to inhibit or enhance microorganism growth.
