Abstract
A tissue plication device and method of using the same is described. The tissue plication device includes a helical fastener having a distal portion with a first pitch and a proximal portion with a second pitch that is smaller than the first pitch. The method includes introducing the distal tip of the helical fastener into the tissue and advancing the helical fastener to plicate the tissue. Another tissue plication device includes a helical fastener having a first configuration with a first pitch and a second configuration with a second pitch. The helical fastener in the first configuration is advanced into a tissue and then converted to the second configuration by applying a stimulus.
