Abstract

A surgical fastener system can comprise a plurality of fasteners which can be connected to one another by a retention matrix which is assembled to the fasteners in order to capture tissue therebetween. In various embodiments, each fastener can comprise a base and the distance in which the retention matrix is seated relative to the fastener bases can be selectively determined by a surgeon in order to apply a desired pressure to the tissue. In certain embodiments, each fastener can further comprise a fastener leg and the retention matrix can comprise a first layer configured to engage the fastener legs. The retention matrix can further comprise a second layer mounted to the first layer which can comprise one or more encapsulations containing a medicine therein. The encapsulations can be aligned with retention apertures in the retention matrix such that they can be punctured by the fastener legs.

Claims

1. A surgical stapling system, comprising:

a first staple comprised of a wire, wherein said first staple comprises;

a first base; and

a first leg extending from said first base;

a second staple comprised of a wire, wherein said second staple comprises;

a second retention aperture configured to receive said second leg; and

a second retention member configured to engage said second leg.

2. The surgical stapling system of claim 1, wherein said first retention member extends into said first retention aperture and is configured to deflect away from said first base when said first leg is inserted into said first retention aperture, and wherein said second retention member extends into said second retention aperture and is configured to deflect away from said second base when said second leg is inserted into said second retention aperture.

3. The surgical stapling system of claim 1, wherein said first retention aperture is defined by a first perimeter and wherein said first retention member defines at least a portion of said first perimeter, and wherein said second retention aperture is defined by a second perimeter and wherein said second retention member defines at least a portion of said second perimeter.

4. The surgical stapling system of claim 1, wherein said retention matrix comprises a sheet of material including a first side facing toward said first base and said second base and a second side facing away from said first base and said second base, wherein said first retention member comprises a first cantilever extending away from said second side, and wherein said second retention member comprises a second cantilever extending away from said second side.

5. The surgical stapling system of claim 1, wherein said retention matrix comprises:

a first sheet of material including a first side facing toward said first base and said second base and a second side facing away from said first base and said second base; and
