Surgical staples having compressible or crushable members for securing tissue therein and stapling instruments for deploying the same

A surgical staple insertable into tissue, said surgical staple comprising:

• a wire comprising a base, wherein said wire is comprised of a first material;
• a crown attached to and at least partially surrounding said base, wherein said crown is comprised of a second material which is different than said first material;
• a first deformable member extending from said base, wherein said wire further comprises said first deformable member;
• a second deformable member extending from said base, wherein said wire further comprises said second deformable member;
• and
• compressing means for compressing said tissue against at least one of said first deformable member and said second deformable member;
• wherein said compressing means comprises:
• first and second ends attached to said crown;
• and
• a curved portion intermediate said first and second ends and configured to contact tissue.

A method of fastening tissue

• inserting a surgical staple into tissue, said staple comprising:
• a wire comprising a base, wherein said wire is comprised of a first material;
• a crown attached to and at least partially surrounding said base, wherein said crown is comprised of a second material which is different than said first material;
• a first deformable member extending from said base, wherein said wire further comprises said first deformable member;
• a second deformable member extending from said base, wherein said wire further comprises said second deformable member;
• and
• a spring extending from said crown, said spring configured to bias said tissue against at least one of said first deformable member and said second deformable member, said spring extending intermediate said first deformable member and said second deformable member;
• wherein said spring comprises:
• first and second ends attached to said crown;
• and
• a curved portion intermediate said first and second ends and configured to contact tissue;
• deforming the first and second deformable members;
• and
• biasing said tissue, by said spring, against at least one of said first deformable member and said second deformable member.
