TISSUE FASTENERS AND RELATED INSERTION DEVICES, MECHANISMS, AND METHODS

摘要

A tissue fastener includes a bridge section and two cannulated leg sectio ns. The tissue fastener is a single piece of material, and the material can be a bioabsorbable material. Each of the two leg sections can include at lea st one barb for resisting dislodgement from tissue after the fastener is ins erted into tissue. The bridge can be flexible, and the leg sections can rece ive needles to allow insertion of the fastener into tissue from above a surf ace of the tissue. Various insertion devices and mechanisms are possible to deploy the fastener into a wound in a patient's skin from above the surface of and generally perpendicular to the skin.
