Abstract:
A biopsy needle includes tissue capture elements within the needle lumen to help hold a tissue sample within the needle and maintain its integrity. According to one aspect, several flexible members form a structure that allows tissue to enter the lumen during advancement of the needle into tissue, and prevents the tissue sample from exiting the needle during retraction of the needle. The flexible members may, in some embodiments, include cutting edges configured to cut the tissue sample from the target tissue mass at the start of needle extraction.
