摘要： Compositions and methods are provided for forming tissue-adherent hydrogels using substantially dry precursors. The dehydrated precursors are premixed prior to in situ therapy and utilize naturally-occurring body fluids as an aqueous environment that initiates transformation, which causes dissolution and nearly simultaneous crosslinking of the precursors, thus forming an insoluble hydrogel implant. The dehydrated precursor-based hydrogels may be used as sealants for fluid leaks from tissue, as adherent drug delivery depots, as means for augmenting and/or supporting tissue, and as means for serving a variety of other useful medical and surgical purposes.

摘要： A planar, solid-state electrochemical oxygen sensor having a substrate, conductive strips deposited on the substrate, and a dielectric layer insulating portions of the conductive strips except those portions which define a working electrode and at least one second electrode. The working electrode may be defined by an open printed region of the dielectric, or by a needle-punched or laser-burned hole or opening in the dielectric which exposes a small region of one of the conductive strips. A solid electrolyte contacting the electrodes is covered by a semipermeable membrane which may comprise an acrylonitrile butadiene copolymer or an acrylate-based copolymer. A sample chamber is defined by the membrane, a cover member, and a gasket therebetween, and has a volume of from about 1 to about 2 .mu.l. The gasket is formulated from the highly cross-linked polymerization product of epichlorohydrin. All sensor components are selected such that a sensor operable for at least 2 days under normal conditions is produced.
