  • Patent number: 8226713
    Abstract: A coating for an orbital implant where the coating has an anterior portion having a different, longer term bioabsorbability than a posterior portion. This allows the implant to have a smooth surface for insertion and to provide reduced irritation to neighboring tissues, to help prevent exposure of the porous core of the implant, and to provide a stable anchorment for extraocular muscles, but which also encourages rapid fibrovascular ingrowth. The coating is marked with a visual indicator to facilitate proper orientation. Shell materials are further selected to allow for sterile packaging, the securing of therapeutic agents thereon, and to provide adequately strong securing of the coating to the core. Apertures are formed through the coating to enhance fluid flow to and from the core, and to provide exposure of the surface of the core to extraocular muscles, and for sutures. The apertures are sized and shaped to reduce irritating surface contact with orbital tissues.

  • Patent number: 7972284
    Abstract: A method of preventing nerve damage positional injury during surgery includes providing a nerve damage positional injury pressure monitoring system including a site sensor with a transducer in the form of a transducer element and a ring extending outward from the transducer element, and a monitor connected to the site sensor; adhering the ring of the site sensor to the patient so that the transducer element forms a protective barrier in front of the area of the patient prone to nerve damage positional injury during surgery; using the system to continuously monitor pressure on the protective barrier formed by the transducer element in front of the area of the patient prone to nerve damage positional injury during surgery with the site sensor and monitor; and causing an alarm to be actuated to alert medical personnel of a pressure condition when monitored pressure is greater than a predetermined threshold.

  • Publication number: 20100121439
    Abstract: A coating for an orbital implant has an anterior portion having a different bioabsorbability than a posterior portion. This allows the implant to have an insertion surface, to reduce irritation, to prevent implant exposure, and to anchor muscles. The coating has a visual indicator to facilitate orientation. Shell materials are further selected to allow for sterile packaging, to secure therapeutic agents thereon, and to secure the coating to the core. Passageways enhance fluid flow to and from the core, and expose the core surface to muscles. The passageways are sized and shaped to reduce irritation. In an alternate embodiment, the anterior coating portion has a vaulted zone creating a gap between the undersurface of the coating and the outer surface of the core through which a suture can easily pass. Perforations through the coating provide targets for passage of the suture through the coating.

  • Patent number: 4976731
    Abstract: Highly satisfactory orbital implants comprising granular hydroxyapatite and spheres of porous, low density hydroxyapatite are described. The implants are useful in enucleation and evisceration procedures. In enucleation procedures, the implants can be sutured to the eye muscles by either insertion in a scleral sac or other suitable container or, in the cast of spherical hydroxyapatite, sutured to the eye muscles by means of holes in the spheres. After healing, the implant is drilled to receive a peg for fixing an artificial eye to the implant to complete the prosthesis.
