20130006271 | Fasteners, Deployment Systems, and Methods for Ophthalmic Tissue Closure and Fixation of Ophthalmic Prostheses and Other Uses - Methods and devices for ophthalmic tissue closure and fixation of ophthalmic prostheses are provided. In accordance with some embodiments, devices for both grasping and clipping a plurality of ocular tissue and ocular prostheses are provided. Various device embodiments are provided for both malleable clips and delivery of normally closed clips (i.e. shape memory). The device may accommodate a plurality of clips which include, but are not limited to: malleable metals, absorbable, shape memory, drug-eluting, and adhesive dispensing. The clips may be pigmented to match the colors of associated tissue (cornea, iris, conjunctiva, sclera, retina) to serve to camouflage fixation clips for healing duration or permanently. According to one aspect, shallow angle access to anatomy may be provided by specialized angulation of device shaft and closure jaws that are intended to access the eye through a small self-healing cornea incision and/or any ocular tissue. | 01-03-2013 |
20130168432 | Fasteners, Deployment Systems, and Methods for Ophthalmic Tissue Closure and Fixation of Ophthalmic Prostheses and Other Uses - 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. | 07-04-2013 |
20140052046 | REDUCTION OF INTRAOCULAR PRESSURE IN THE EYE USING A TUBULAR CLIP - Drainage of aqueous from the anterior chamber of the eye can be facilitated by a malleable hollow clip or staple that can be formed to attach to ophthalmic tissue and provide intra-luminal flow of aqueous through the clip. In addition, the clip can be adjusted to modulate the outflow rate of aqueous, both during the initial surgical procedure as well as on a post-procedure basis. Furthermore, an instrument is described in which the forceps of the clip delivery device reside inside the lumen of hollow clip during deployment and manipulation. Features of an instrument are designed to secure the clip to the delivery forceps and prevent tissue blockage of the clip lumens. The clips may be color-matched to the underlying tissue for the purpose of camouflage and may carry pharmaceuticals. | 02-20-2014 |
