Abstract
An orbital implant device for implantation into the orbit, particularly for children. The orbital implant device comprises a substantially rigid sphere having a self-sealing infusion site, and an integral expandable balloon overlying the posterior position of the sphere which is in communication with the self-sealing infusion site to permit increasing the effective size of the orbital implant device as the child's bone structure increases in size.
Claims18
An orbital implant device for an eye prosthesis adapted for fitting into an orbit comprising:
- a substantially rigid sphere with a substantially smooth exterior surface along at least an anterior portion thereof adapted to receive a cosmetic eye appliance;
- an expandable balloon integrally attached to and overlying a posterior portion of said substantially rigid sphere to define an expandable space adapted to receive a quantity of fluid;
- and
- a self-sealing infusion site on said anterior portion of said substantially rigid sphere which communicates with said expandable space and which is adapted to receive a hollow needle to adjust said quantity of said fluid in said expandable space to thereby adjust a dimension of said expandable balloon.
An orbital implant device for an eye prosthesis adapted for fitting into an orbit comprising;
- a substantially rigid sphere with a substantially smooth exterior surface along at least an anterior portion thereof adapted to receive a cosmetic eye appliance;
- an expandable balloon integrally attached to and overlying a posterior portion of said substantially rigid sphere to define an expandable space adapted to receive a quantity of fluid;
- a circumferential ridge extending outwardly from said substantially rigid sphere for securing said orbital implant device in said orbit;
- and
- a self-sealing infusion site on said anterior portion of said substantially rigid sphere which communicates with said expandable space and which is adapted to receive a hollow needle to adjust said quantity of said fluid in said expandable space to thereby adjust a dimension of said expandable balloon.
An orbital implant device for an eye prosthesis adapted for fitting into an orbit comprising;
- a substantially rigid sphere inert to animal tissue, with a substantially smooth exterior surface along at least an anterior portion thereof adapted to receive a cosmetic eye appliance;
- a reinforcing ridge circumferentially located around said anterior portion of said substantially rigid sphere with at least two attachment sites thereon adapted to receive sutures for securing said orbital implant device in said orbit;
- an expandable balloon integrally attached to and overlying a posterior portion of said substantially rigid sphere to define an expandable space adapted to receive a quantity of fluid;
- a reinforcement member inside said sphere;
- a self-sealing infusion site on said substantially rigid sphere to accept a hollow needle for injecting said quantity of fluid;
- and
- a cavity inside said substantially rigid sphere which receives said quantity of fluid from said hollow needle, said cavity communicating with said expandable space through said reinforcement member to adjust said quantity of said fluid in said expandable space to thereby adjust a dimension of said expandable balloon.
