Fasteners, Deployment Systems, and Methods for Ophthalmic Tissue Closure and Fixation of Ophthalmic Prostheses and Other Uses

摘要

Improved tissue fasteners are disclosed that can be inserted into (and optionally through) tissue structures underlying a tissue surface for affixing overlapping tissues and tissue planes together, and the like. In some embodiments, an elongate anvil body may protrude distally and/or laterally from a fastener support disposed along the base. The anvil body may have a sharpened end and be configured to penetrate into the tissue, with the elongate anvil body optionally having a bend from a more distal orientation adjacent the clip support to a more lateral orientation adjacent the sharpened end during at least a portion of the deployment. The first leg can be driven through a desired location on the surface of the first tissue and against a receptacle of the anvil body so as to deform the fastener and affix it to the first tissue.

主权项

1. A device for deploying a surgical fastener in a tissue, the device comprising:
an anvil; a rotatable lobe coupled with the anvil, the rotatable lobe including a tissue engaging surface configured for placement distally against a surface of the tissue; and wherein the lobe is rotatable against the surface of the tissue to control a location of the anvil relative to the tissue during deployment of the fastener into the tissue.
