Epiretinal Prosthesis Surgically Implanted in the Eye

A miniature video camera housed in a pair of glasses captures a scene and relays the information to a receiver in the implant.In a healthy eye, the photoreceptors (rods and cones) on the retina convert light into tiny electrochemical impulses that are sent through the optic nerve and into the brain, where they are decoded into images. If the photoreceptors no longer function correctly — due to conditions such as retinitis pigmentosa — the first step in this process is disrupted, and the visual system cannot transform light into images.

Biosensing Technology Offers Advanced Diagnostic Capabilities

An electronic biosensing platform, combining nanoelectronics and three-dimensional electronic system integration, could replace the conventional microplate.Electronic biosensing technology could someday displace the multi-welled microplate, long a standard tool in biomedical research and diagnostic laboratories. Essentially arrays of tiny test tubes, microplates have been used for decades to simultaneously test multiple samples for their responses to chemicals, living organisms, or antibodies. Fluorescence or color changes in labels associated with compounds on the plates can signal the presence of particular proteins or gene sequences.

Die Extrusion Technology for Medical Tubing Applications

Patent-pending process would allow 1000-plus layers from a single extruder.Although the concept of nanotechnology (controlling matter on an atomic scale) dates back to 1959, it is only now becoming more commercially realized. It has the potential to challenge the way all products are extruded in almost every type of medical tubular or related industrial product applications.

Blood Pressure Monitoring Tool

A computer control mouse device includes a sphygmomanometer and software package to take recordings and store them as digital data.The MDMouse system incorporates a pre-existing medical device into a conventional computer control mouse. The tool is designed to measure blood pressure outside of the medical environment, and to provide that information for use by individuals, clinical evaluation companies (CROs), healthcare providers, and healthcare payers.

Laser Sintering for Customized Medical Applications

Additive, layer-by-layer manufacturing process allows for the manufacture of complex geometries in plastic and metal implants and orthoses.Engineers have long been aware of the potential of laser sintering to create innovative and beneficial medical products. Because it is an additive (layer-by-layer) manufacturing process, laser sintering can build parts free of the traditional constraints imposed by machining or molding.Recent medical applications of laser sintering are now demonstrating the technology’s unique capabilities for mass customization and the manufacture of designs with complex geometries in both plastics and metals.

Cubic-Millimeter Energy-Autonomous Wireless Intraocular Pressure Monitor

Once implanted in the eye, this complete millimeter-scale computing system tracks the progress of glaucoma.A prototype implantable eye pressure monitor for glaucoma patients is believed to contain the first complete millimeter-scale computing system. The pressure monitor is designed to be implanted in the eye to conveniently and continuously track the progress of glaucoma, a potentially blinding disease. It is expected to be commercially available in several years.
