摘要:
Devices and methods are provided for treatment of tissue in a body lumen with an electrode deployment device. Embodiments typically include a device with a plurality of electrodes having a pre-selected electrode density arranged on the surface of a support. The support may comprise a non-distensible electrode backing that is spirally furled about an axis and coupled to an expansion member such as an inflatable elastic balloon. In some embodiments, the balloon is inflated to selectively expose a portion of the electrode surface while maintaining the electrode density.

摘要:
A triarylsulfonium complex salt is described which has particular utility as a photoinitiator for the polymerization of epoxide monomers in thick films or coatings. Photopolymerizable compositions are also described.
摘要:
Aromatic sulfonium compounds are sensitized to longer wavelengths of light by means of aromatic tertiary amines, aromatic tertiary diamines and certain aromatic polycyclic compounds.
摘要:
Light sensitive diazonium compounds having an aromatic stable light sensitive nucleus with a bis-(fluorinated alkylsulfonyl) methide anion are found to be useful for many photosensitive systems. The fluorinated sulfonyl contains a highly fluorinated alkyl moiety.

A bunded tank system suitable for both transport and storage of bulk dangerous industrial liquids is provided. Preferably the tank is containerised to provide efficient use of space and improved logistics for transport and storage. The containerised bunded tank system includes a plurality of bunded sub-tanks arranged in an interlocking manner within an ISO container. In addition the container is fitted with an improved container lock.
摘要:
A system for plugging holes in vessels which comprises the combination of a storage and delivery system for a foam-forming material, and a hole-plugging assembly. The hole-plugging assembly includes a flexible nonelastic bag member which is inserted in a folded position into the hole to be plugged and properly positioned with an associated locating means. Thereafter, a unitary foamable material is injected into the bag member to expand it and seal the hole. The locating means further assists in maintaining the inflated bag member in proper orientation and sealing engagement while the foam is curing.
