A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

Disclosed are methods of delivering an agent to the lumen of the vas deferens under guidance of ultrasound imaging. The methods include vas-occlusive contraception in which the vas deferens is non-surgically isolated and an occlusive substance is percutaneously administered into the lumen of the vas deferens under ultrasound. Also disclosed are methods of reversal of vas-occlusive contraception and methods of delivering an agent to the lumen of the vas deferens. Also disclosed are compositions for use in the methods of the invention.
