Electronystagmography (ENG) systems are used to evaluate people with vertigo and certain other disorders that affect hearing and vision. Electrodes are placed at locations above and below the eye to record electrical activity. By measuring the changes in the electrical field within the eye, ENG can detect nystagmus in response to various stimuli. If nystagmus does not occur upon stimulation, a problem may exist within the ear, nerves that supply the ear, or certain parts of the brain.

Cortical stimulator is a medical device, which is used to revive neural activity in the nervous system of critical patients by delivering an electrical shock to induce brain activity. It is almost always attached to the temples or foreheads of humanoids. It is an electronic instrument used in nerve and mental therapy to deliver an electric shock of prescribed strength by means of a pulsating current.

Neuromuscular stimulators are designed to electronically stimulate muscles for people managing chronic or acute pain. It has dual channels and a pulse frequency. This stimulator also includes an adjustable contraction and relaxtion variable control of 1-10 seconds.

Female intrauterine device is a small plastic device that is inserted into the uterus. Its contraceptive action begins as soon as the device is placed in the uterus and stops as soon as it is removed. It is used to prevent pregnancy.

Hollow silastic band is placed around the upper part of the stomach, limiting the amount of food a person can eat. It can be adjusted after surgery by injecting or removing saline from the band with a needle.

Egg-shaped bioceramic orbital implants insert easily into orbital socket and will not cling to surrounding tissue. Improved interconnectivity between pores enhances vascularization. Implants may be easily drilled without crumbling.

An emergency eyewash solution provides a sterile soothing, normal saline wash to wash away soluble irritants.

An eye loupe has the function of magnifying the image and of increasing the refractive power of the eye so that a given source can be imaged at closer distance than would be the case for an unaided eye.

Eyelid procedures, mucotomes are designed for mucosal repair surgery. It comprises a handle having a small, compactly designed cutting head arranged on its forward end. The cutting head includes a circular cylindrical blade-holding roller which is reciprocable parallel to the blade edge in a guide by means of a drive shaft having an eccentric crank pin engaging in cross grooves of the blade-holding roller.

Electroretinography (ERG) system is used to measure the electrical response of the eye's light-sensitive cells (rods and cones). It records the changes in electropotential across the retina upon a flash stimulus. Electrodes are placed on the cornea and the skin near the eye. During a recording, the patient is watching a standardized stimulus and the resulting signal is interpreted in terms of its amplitude and time course.

Eyed pigtail probe is mainly used for canalicular repair. It is used to position the silicone tube for canalicular intubation. The technique of upper system cerclage is accomplished using the pigtail probe. It is inserted through the upper canaliculus and then threaded through the internal common punctum out through the lower canaliculus and punctum.

Extended duration punctum plugs are designed to provide patient comfort for up to three months. These long lasting plugs are effective and economical for transient dry eye symptoms following surgery.

Electrical Bone Growth Stimulator is a medical device that uses an electric field or current to stimulate the growth of bone tissue. It may be worn on the outside of the body or can be surgically implanted around the area requiring treatment.

External non-invasive bone stimulator provides stimulation through electrical and/or magnetic fields to promote osteogenesis to facilitate the healing of nonunion fractures and lumbar spinal fusions. The stimulation may be delivered through capacitive coupling ('CC) with electrodes placed directly over the treatment site, or through pulsed electromagnetic fields (PEMF) with treatment coils placed into a brace or over a cast at the treatment site. It is intended for use for the treatment of established nonunion fractures acquired secondary to trauma and as an adjunct to the treatment of lumbar spinal fusion surgery for one or two levels.

Ergonomic hand exerciser provides resistance training for hands, fingers and forearms. It helps strengthen grip and increases finger dexterity. It makes a great stress reliever. It comes in soft and firm resistance.

Electrosurgical reusable handswitching pen is commonly used accessory in electrosurgery procedures.
