摘要:
Described herein is a process for fabricating microfluidic systems with embedded components in which micron-scale features are molded into the polymeric material polydimethylsiloxane (PDMS). Micromachining is used to create a mold master and the liquid precursors for PDMS are poured over the mold and allowed to cure. The PDMS is then removed form the mold and bonded to another material such as PDMS, glass, or silicon after a simple surface preparation step to form sealed microchannels.

An image is captured or otherwise converted into a signal in an artificial vision system. The signal is transmitted to the retina utilizing an implant. The implant consists of a polymer substrate made of a compliant material such as poly(dimethylsiloxane) or PDMS. The polymer substrate is conformable to the shape of the retina. Electrodes and conductive leads are embedded in the polymer substrate. The conductive leads and the electrodes transmit the signal representing the image to the cells in the retina. The signal representing the image stimulates cells in the retina.

A flexible cable comprises a cable body of a silicone material and circuits in the flexible cable body. In one embodiment the flexible cable body comprises a multiple number of individual layers of poly(dimethylsiloxane). In one embodiment silicone material encapsulates the individual layers. The flexible cable is made by providing a multiplicity of substrates of a flexible silicone material, producing circuits in the substrates, and stacking the multiplicity of substrates to produce the high density flexible cable.

A device for delivering a therapeutic agent into tissue includes: an elongated body; and a first balloon in the body expandable from a collapsed position to an expanded position; and a second balloon in the body expandable from a collapsed position to an expanded position. The second balloon has a plurality of apertures therein. A therapeutic agent is located in the second balloon. A plurality of microprojections are located on a surface of the second balloon for penetrating tissue. Upon expansion of the first balloon from the collapsed position to the expanded position, the second balloon is expanded from the collapsed position to the expanded position for deploying the plurality of microprojections into tissue and for dispensing the therapeutic agent from the second balloon into the tissue through the plurality of apertures.
摘要:
A peel and stick electronic system comprises a silicone body, and at least one electronic unit operatively connected to the silicone body. The electronic system is produce by providing a silicone layer on a substrate, providing a metal layer on the silicone layer, and providing at least one electronic unit connected to the metal layer.
摘要:
Various embodiments of a “smart” drug delivery system are provided which includes an add-on module and a reusable or disposable drug pen. Upon attachment to the pen, the add-on module may: determine dosage selected, injection of selected dosage, duration of injection, time of injection, whether the pen has been primed or shaken to thoroughly mix up insulin mixtures, transmit information relating to insulin dosage and injection to a data management unit, provide reminders, error warning or messages on improper usage or reusage of needles, track amount of drug remaining on board the pen or duration of usage of pen with respect to expiry of the drug on board, or provide an audible alarm for locating misplaced pen and module.
