When I was at MIT, I was involved in some mechanical engineering research modifying biopsy needles. Hence, I am naturally intrigued when new biopsy needles are engineered.
A company in California called Rubicor has developed a new type of biopsy needled called FLASH. This single-insertion, multi-sample biopsy needle can take up to 15 core samples with one incision. Certainly beats those spring-loaded biopsy needles that make a horrible clicking sound when they 'fire' to cut a core of tissue.
