How to use them, as well as skirts and atraumatic occlusion balloon

摘要

One aspect of the invention relates to catheters that can be placed within the body conduit or around to occlude or extend the biological lumen without causing significant trauma to the body lumen. In some embodiments, the invention is particularly directed to the use of the polymeric composition is inserted into the balloon or skirt may be a gel. In some embodiments, it swells viscous polymer composition is a liquid at room temperature, a gel at physiological temperatures in mammals. In some embodiments, swell viscous polymer composition was optionally purified, an inverse thermosensitive polymer.
