T-Peel Strength of Tissue Adhesives

0 0

Tissue adhesives are used in bandages, wound closure and surgical sealants. Based on regulatory requirements, tissue adhesive strength in each of these applications must be clearly established before use. Weak tissue adhesive strength may lead to infection or poor healing. High strength tissue adhesives may damage the tissue upon removal.

ASTM F2256 is a common standard used to determine the means for comparison of the adhesive strengths of tissue adhesives intended for use as surgical adhesives or sealants, or both, on soft tissue. Tissue adhesives are becoming increasingly common in the medical industry. Applications include sutures, bandages, and surgical wound dressing. A weak adhesive could lead to infection or tearing, whereas an adhesive which is too strong could lead to tissue damage upon removal. Therefore the tissue strength must be mechanically defined before the device is used on humans.
