EXPANDABLE BACKSPAN STAPLE
First Claim
Patent Images
1. :
- A surgical staple formed from a biocompatible material suitable for joining tissue segments, the surgical staple comprising;
a first leg having a first end and a second end;
a second leg having a first end and a second end;
a backspan having a first end portion extending from the first end of the first leg, a second end portion extending from the first end of the second leg, and a central portion extending between the first and second end portions; and
a compressible member positioned adjacent the backspan such that the tissue segments are compressed between the compressible member and the first and second legs upon formation of the surgical staple in a manner sufficient to effect hemostasis.

Abstract
A staple having an expandable backspan and a pair of spaced legs is described. The expandable backspan is configured to expand or deform to accommodate tissues of varying thicknesses. In one embodiment, the backspan is non-linear and defines a recess. In another embodiment, the backspan includes a deformable pad or spacer. The amount of deformation of the backspan is proportional to the thickness of the tissue, i.e., the greater the thickness of tissue, the greater the deformation of the backspan.

18. :
- A surgical staple formed from a biocompatible material suitable for joining tissue segments and having a formed and unformed condition, the surgical staple comprising;
first and second legs including penetrating ends; a backspan extending between the first and second legs and including a substantially non-linear configuration in the unformed condition, the backspan being reconfigurable upon the application of a force thereto by the tissue segments upon formation of the surgical staple to the formed condition to progressively linearize the backspan; and a spacer member formed from a compressible material and being positioned adjacent the backspan such that the tissue segments are compressed between the spacer member and the first and second legs upon formation of the surgical staple to in a manner sufficient to effect hemostasis, whereupon tissue segments having a first thickness will apply a first compressive force to the surgical staple resulting in deformation of the spacer member, and tissue segments having a second, greater thickness will apply a second, greater compressive force to the surgical staple resulting in deformation of the spacer member and reconfiguration of the backspan. - View Dependent Claims (19, 20)
