Abstract

A surgical fastener system can comprise a plurality of fasteners which can be connected to each other by a flexible retention matrix which is assembled to the fasteners in order to capture tissue therebetween. The flexible retention matrix can comprise, one, a plurality of retention matrix elements configured to engage the fasteners and, two, a lattice of connectors which connect one or more retention matrix elements.

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 base; and

a second leg extending from said second base; and

a retention matrix, comprising;

a first matrix element, comprising;

a first aperture configured to receive said first leg; and

a first retention member configured to engage said first leg;

a second matrix element, comprising;

a second aperture configured to receive said second leg; and

a second retention member configured to engage said second leg; and

a connecting link connecting said first matrix element and said second matrix element, wherein said first matrix element and said second matrix element are comprised of a metal material, wherein said connecting link is comprised of a plastic material, and wherein said plastic material of said connecting link at least partially surrounds said first matrix element and said second matrix element.

2. 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 base; and

a second leg extending from said second base; and

a retention matrix, comprising;

a first matrix element, comprising;
