A team of biomedical engineering researchers from Carnegie Mellon University and the University of Louisville are developing surgical tools that could be used for future expeditionary spaceflights to the moon, an asteroid or Mars.

"In deep space, surgical procedures will be severely complicated by absence of gravity, where it becomes difficult to prevent cabin contamination from blood and body fluids," said James Antaki, a professor of biomedical engineering at CMU.

To address these challenges of surgical care in zero gravity, Antaki along with George M. Pantalos, a professor of surgery and bioengineering at the University of Louisville, and CMU researchers James E. Burgess and Jennifer A. Hayden are developing a watertight surgery system to isolate the wound and control bleeding by creating a pressurized aqueous environment within the surgical field.

"We have developed a dome-shaped structure [Aqueous Immersion Surgical System (AISS)] that can be mounted over the surgical area and will prevent contamination of the spacecraft cabin during surgeries that could include working on broken limbs or traumatic injuries," said Hayden, a Ph.D. biomedical engineering student from South Brunswick, N.J. The AISS is also designed to reduce or stop bleeding.

The system could potentially be used for a wide variety of ground-based surgery. In the U.S. alone, the number of patients undergoing major surgical procedures is estimated at 32.7 million annually.

Prototypes of the astro-surgical system will be tested on four separate flights of NASA's zero-gravity C-9 aircraft from Oct. 2-5 at Johnso
