Surgical staple having a deformable member with a non-circular cross-sectional geometry
A surgical staple including at least one deformable member which can be bent upon contacting an anvil of a surgical stapler. In various embodiments, at least a portion of the deformable member can include a non-circular cross-section which can dictate the direction and manner in which the deformable member is bent. In at least one various embodiment, the non-circular cross-section can include a flat portion which can cause the deformable member to bend in the direction of the flat portion. In various embodiments, the non-circular portion of the cross-section can be configured to abut soft tissue of a patient and apply a compressive force or pressure thereto. In various embodiments, a crown formed on the surgical staple can dissolve as the soft tissue heals and can, depending on the cross-sectional geometry of the deformable member, reduce the force or pressure applied to the soft tissue by the deformable member.
1 . A surgical staple, comprising:
a base;
a crown, wherein said crown is comprised of a first dissolvable material; and
a first deformable member extending from said base, wherein at least a portion of said first deformable member includes a non-circular cross-section.
2 . The surgical staple of claim 1 , wherein said crown is overmolded onto said base.
3 . The surgical staple of claim 1 , further comprising a second deformable member extending from said base, wherein at least a portion of said second deformable member includes a non-circular cross-section.
4 . The surgical staple of claim 1 , wherein said first deformable member is comprised of a non-dissolvable material.
5 . The surgical staple of claim 1 , wherein said first deformable member is comprised of a second dissolvable material.
6 . The surgical staple of claim 1 , wherein said crown further includes at least one second material, wherein said second material comprises a therapeutic drug, and wherein the dissolution of said crown releases said therapeutic drug.
7 . The surgical staple of claim 1 , wherein said non-circular cross-section includes at least one flat surface.
8 . The surgical staple of claim 7 , wherein said non-circular cross-section further includes at least one arcuate surface.
9 . The surgical staple of claim 1 , wherein said non-circular cross-section includes a first flat surface and a second flat surface, and wherein said first flat surface is substantially parallel to said second flat surface.
10 . The surgical staple of claim 1 , wherein said first deformable member includes an end, and wherein said end includes said non-circular cross-section.
11 . A surgical staple, comprising:
a base;
a crown, wherein said crown is comprised of a first bioabsorbable material;
a first deformable member extending from said base, wherein at least a portion of said first deformable member includes a cross-section having at least one flat surface.
12 . The surgical staple of claim 11 , wherein said crown is overmolded onto said base.
13 . The surgical staple of claim 11 , further comprising a second deformable member extending from said base, wherein at least a portion of said second deformable member includes a cross-section having at least one flat surface.
14 . The surgical staple of claim 11 , wherein said first deformable member is comprised of a non-bioabsorbable material.
15 . The surgical staple of claim 11 , wherein said first deformable member is comprised of a second bioabsorbable material.
16 . The surgical staple of claim 11 , wherein said crown further includes at least one second material, wherein said second material comprises a therapeutic drug, and wherein the absorption of said first material releases said therapeutic drug.
17 . The surgical staple of claim 11 , wherein said cross-section further includes at least one arcuate surface.
18 . The surgical staple of claim 11 , wherein said at least one flat surface includes a first flat surface and a second flat surface, and wherein said first flat surface is substantially parallel to said second flat surface.
19 . The surgical staple of claim 11 , wherein said first deformable member includes an end, and wherein said end includes said flat surface.
20 . A surgical staple, comprising:
a base;
a first deformable member extending from said base, wherein said first deformable member is configured to capture soft tissue intermediate said first deformable member and said base, and wherein at least a portion of said first deformable member includes a non-circular cross-section; and
dissolvable means for applying a first force against the soft tissue before the dissolvable means has dissolved and for applying a second force against the soft tissue after at least a portion of the dissolvable means has dissolved.
