摘要：
One aspect of the present invention relates to catheters that can be placed in or around bodily conduits to occlude or widen a biological lumen without imparting significant trauma to the lumen. In certain embodiments, the invention particularly relates to the use of a polymer composition which can be made to gel upon insertion into said balloon or skirt. In certain embodiments, the inflating viscous polymer composition is a liquid at room temperature and a gel at mammalian physiological temperature. In certain embodiments, the inflating viscous polymer composition comprises an optionally purified inverse thermosensitive polymer.
