A new “smart catheter” that senses the start of an infection, and automatically releases an anti-bacterial substance, is being developed to combat the problem of catheter-related blood and urinary tract infections, scientists reported in Baltimore on August 23 at the 244th National Meeting & Exposition of the American Chemical Society.
Dipankar Koley, Ph.D., who delivered the report, said the “smart catheter” technology is being developed for both catheters inserted into blood vessels and the urinary tract.
“About 1.5 million healthcare-associated infections are reported in the United States alone each year, resulting in 99,000 deaths and up to $45 billion in extra health care costs,” said Koley.

JOINT REPLACEMENT SURGERY
Joint replacement is one of the most common and successful operations in modern orthopaedic surgery. It consists of replacing painful, arthritic, worn or diseased parts of the joint with artificial surfaces shaped in such a way as to allow joint movement.
Arthroplasty is a common but loose term for joint replacement. Other types of surgery are also arthroplasties. Other common and valid synonyms are total joint replacement, total joint arthroplasty, joint resurfacing and artificial joint surgery.
