    摘要: A surgical staple including features which can reduce bleeding from soft tissue. In various embodiments, the surgical staple can include at least one deformable member which can puncture a hole in soft tissue as it is inserted therethrough. The deformable member can include a material thereon, or can be comprised of a material, which can expand and substantially fill the puncture hole in the soft tissue. In various embodiments, at least a portion of the deformable member can be coated with a hydrophilic material which can expand when exposed to water, or other bodily fluids, and apply a compression force to the perimeter of the puncture hole. Such a compression force can reduce bleeding from the puncture hole and thereby reduce any potential complications resulting therefrom.
