Abstract
Abstract A hemostatic clip for application to body tissue is disclosed which includes opposed leg portions connected by a bail portion with each leg portion having a tissue contacting surface defined thereon. A pair of projections and a pair of recessed areas are defined on each tissue contacting surface and are disposed in an alternating arrangement such that the movement inhibiting structures on one leg portion are in juxtaposed alignment with those on the opposed leg portion.
