摘要：
This disclosure relates to swellable needles that include a proximal end portion and a swellable distal end portion. Upon exposure to a liquid, the needles are configured to undergo a shape change from a first configuration in which the width of the needle is tapered from the proximal end portion to the distal end portion to a second configuration in which the distal end portion is more swollen than the proximal end portion. The swellable needles can be double layer swellable needles or single material swellable needles.
