The OTE was designed by Dr. David TSE (US patent #6582465). The device consists of a flexible "balloon/expander"
held in place by a titanium fixation plate that is anchored to the lateral orbital wall by screws. A slotted arm attached to the fixation
plate, extends through a slot that is formed within the OTE. The OTE will be self-centered in the expanding socket as the orbit grows.
A 30 gauge disposable hypodermic needle connected to a 1cc disposable syringe filled with sterile saline is inserted into the OTE through
an injection port. The injection track seals upon the removal of the needle. Inflation of the OTE will effect pressure on the orbit of the
The OTE was tested at Dr. Jean-Marie Parel's laboratory, the Ophthalmic Biophysics Center which is part of the Bascom Palmer Eye
Institute at the University of Miami, Miller school of medicine.
The device was developed and is currently manufactured by Innovia LLC.
