Abstract

A staple and stapler and introducer are disclosed for closing a wound and for wound site management. The staple is deformable, and includes a plurality of tissue-piercing prongs which are expanded outwardly, inserted into tissue and collapsed inwardly to close the wound. The stapler includes a plurality of mechanisms to deform the staple into various positions. An introducer is provided that includes a plurality of spaced-apart wire guides for securing and centering the wound opening during a medical procedure, and during closure of the wound.

Claims

1. A tissue staple, comprising:

a plurality of prongs connected to a plurality of tabs and arranged about a centerline axis;

each said prong having a shoulder portion extending substantially orthogonal from said prong toward said centerline axis, each said prong having a tapered tissue-piercing portion on the distal end thereof;

each said tab and prong connected together about said centerline axis in an alternating fashion and axially from said centerline axis, each said prong arranged substantially parallel to said centerline axis, and each said tab extending distally and inwardly toward said centerline axis so that at least an inner portion of each said tab is closer to said centerline axis than said prongs.

2. A staple as claimed in claim 1, said tissue-piercing portion extending from said prong inward toward said centerline axis.

3. A staple as claimed in claim 1, said tab having a U-shape and connected to a prong at each upper portion of said U-shape, said inner portion arranged to translate a force thereon to each said prong, respectively, to move the distal ends of said prongs outward from said centerline axis, pivoting approximately from an outer perimeter of said shoulder portions.

4. A staple as claimed in claim 3, wherein said force causing said U-shape to spread apart as the distal ends of said prongs move outward from said centerline axis.

5. A staple as claimed in claim 1, wherein said prongs, tabs and shoulders being formed in a unitary fashion of a deformable biocompatible and/or bioabsorbable material.

6. A staple as claimed in claim 1, wherein the prongs, tabs and shoulders are symmetrically located about said centerline axis, and said prongs and tabs are arranged in an alternating fashion.

7. A staple as claimed in claim 1, wherein each said prong further comprising a tissue stop portion positioned at a selected point along the length of said prong to limit the penetration of said tissue-piercing portion into tissue.

8. A staple as claimed in claim 1, wherein said prongs, tabs and shoulders being formed in a unitary fashion of an elastic biocompatible and/or bioabsorbable material.

9. A tissue staple, comprising:

a plurality of prongs arranged about a centerline axis, each said prong having a shoulder portion extending substantially orthogonal from said prong toward said centerline axis, and a plurality of web portions connecting each said prong to one another, each said prong having a tapered tissue-piercing portion on the distal end thereof.

10. A tissue staple as claimed in claim 9, wherein said tissue-piercing portion extending from said prong inward toward said centerline axis.

14. A staple as claimed in claim 9, wherein said prongs, web portions and shoulders being formed in a unitary fashion of a deformable biocompatible and/or bioabsorbable material.

15. A staple as claimed in claim 9, wherein the prongs, web portions and shoulders are symmetrically located about said centerline axis, and said prongs and web portions are arranged in an alternating fashion.

16. A staple as claimed in claim 9, wherein each said prong further comprising a tissue stop portion positioned at a selected point along the length of said prong to limit the penetration of said tissue-piercing portion into tissue.

17. A staple as claimed in claim 9, wherein said prongs, web portions and shoulders being formed in a unitary fashion of an elastic biocompatible and/or bioabsorbable material.

11. A tissue staple as claimed in claim 19, wherein each said web portions and said prongs connected together about said centerline axis in an alternating fashion, each said prong arranged substantially parallel to said centerline axis, and each said web portion extending inwardly toward said centerline axis so that at least an inner portion of each said web portion is closer to said centerline axis than said prongs.

12. A tissue staple as claimed in claim 11, said inner portion arranged to deform and translate a force thereon to each said prong, respectively, to move the distal ends of said prongs outward from said centerline axis.

13. A tissue staple as claimed in claim 11, wherein said force causing web portion to deform outwardly from said centerline axis.

18. A tissue staple, comprising:

a plurality of prongs connected to a plurality of tabs and arranged about a centerline axis;

each said prong having a shoulder portion extending substantially orthogonal from said prong toward said centerline axis, each said prong having a tapered tissue-piercing portion on the distal end thereof, wherein each said prong further comprising a tissue stop portion positioned at a selected point along the length of said prong to limit the penetration of said tissue-piercing portion into tissue.
