Background:
Mesh suture used in high-tension wound closures produces large knots susceptible to increased palpability, infection, and foreign body response; yet has superior tensile strength and increased resistance to cutting through tissue compared to standard suture. This study investigates mesh suture fixation in abdominal tissue with a knotless novel, low-profile anchor-clip.
Methods:
Single and double end fixation of mesh suture in swine rectus abdominus fascia with an anchor-clip, a knot, and predicate device fixation underwent cyclic testing followed by pull-to-failure testing.
Results:
Failure load of standard knot, single corkscrew and double anchor-clip were not statistically different, but were significantly greater than single anchor-clip and double corkscrew fixation (p > 0.05).
Conclusions:
The anchor-clip is ∼60% smaller than a standard knot while maintaining fixation strength when exposed to physiologic forces using double anchor-clip fixation in abdominal wall closure.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
