Determine the Suture Retention Strength of Porcine Pericardium
|
|
Background Suture retention tests are performed on synthetic patches and tubular prostheses to see how closely they replicate native tissue mechanical properties and to determine resistance to failure. Researchers have often utilized allografts and xenografts in tissue repair studies, as they closely mimic the mechanical properties of native tissues and eliminate the need for manufacturing prostheses. Porcine pericardium has widely been used to develop heart valves, cardiac tamponade patches, and tubular vascular grafts. These implantations involve suturing, and retention tests can be performed to determine the appropriate suture material and thickness based on the resulting behavior of the sample. |
