Abstract
Abstract A corneal rivet for passing internally through the cornea and for providing closure of an incision in the cornea with a mechanically and optically configured rivet body including a first rivet head secured at one end thereto and a second member for securing to the other end of the rivet. The securing can either be through frictional engagement of the second member to the rivet body, through a knotting, a crimping, staking, threading, pinning, heat forming a ball or mushroom member, or a ratcheting engagement. The corneal rivet body can be utilized to suture other tissues besides the cornea, such as sclera, iris, other ocular tissues, skin, flesh, or the like.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
185 words
Rivet for suturing an closing a bodily incision comprising: a. a configured arched body having a bodily surface penetrating end and a bodily surface engaging end; b. a first rivet head member secured to said bodily surface engaging end of said configured arched body, said head member having a flat bodily surface engaging portion and a thickness small relative to its diameter; c. a securing means for securing said configured arched body bodily surface penetrating end once said penetrating end has exited said body, said securing means comprising a second rivet head member having a flat bodily surface engaging portion and having frictional engaging means for engaging said configured arched body bodily surface penetrating rod; and d. said frictional engaging means further comprising a large diameter aperture through said second rivet head member and having a diameter larger than the diameter of said configured arched body bodily surface penetrating end for slidable insertion of said configured arched body bodily surface penetrating end and a communicating small diameter aperture through said second rivet head member for frictionally engaging said configured arched body bodily surface penetrating end.
