Polyesters were developed in the 1950s, and later the process of radiation sterilization was established for catgut and polyester. Polyglycolic acid was discovered in the 1960s and implemented in the 1970s. Today, most sutures are made of synthetic polymer fibers. Silk and, rarely, gut sutures are the only materials still in use from ancient times.

The Greeks also acknowledged the importance of wound closure, and were the first to differentiate between acute and chronic wounds, calling them "fresh" and "non-healing", respectively. Galen of Pergamum, a Greek surgeon who served Roman gladiators circa 120–201 A.D., made many contributions to the field of wound care. [9]
Wound closure strips applied to a cut on the top of the foot. Wound closure strips are porous surgical tape strips which can be used to close small wounds. They are applied across the laceration in a manner which pulls the skin on either side of the wound together.
Catgut suture is a type of surgical suture made of twisted strands of purified collagen taken from the small intestine of domesticated ruminants or beef tendon. It is naturally degraded by the body's own proteolytic enzymes. Full tensile strength remains for at least 7 days, and absorption is complete by 90 days. This eventual disintegration ...

The first commercial staplers were made of stainless steel with titanium staples loaded into reloadable staple cartridges. Modern surgical staplers are either disposable and made of plastic, or reusable and made of stainless steel. Both types are generally loaded using disposable cartridges. The staple line may be straight, curved or circular.
In October 2019, Taylor invented medical sutures that change color to indicate a wound infection as part of a science fair. [3] [4] During the development of the project, she discovered that many sutures are coated with a material that conducts electrical resistance in wounds, which is then sent to a patient or doctor's device to warn them of an infection.
