摘要:
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.
摘要:
Rotary expansible chamber (REC) devices having one or more working-fluid ports that are adjustable, for example, in size or location. In some embodiments, the variable port mechanisms can be used to control any one or more of a plurality of operating parameters of a REC device independently of one or more others of the operating parameters. In some embodiments, the REC devices can have a plurality of fluid volumes that change in size during rotation of the REC device, and that transition to a zero volume condition during the rotation of the REC device. Systems are also provided that can include one or more REC devices. Methods for controlling various aspects of REC devices, including methods of controlling one or more operating parameters, are also provided.
