SINGLE LUMEN BALLOON CATHETER HAVING CHEMICAL-RESISTANT OR ADHERENCE-RESISTANT BALLOON SECTION.

摘要

This invention is a surgical device. In particular, it is low profile, single lumen catheter preferably having a movable seal or seat that allows the balloon to be inflated by sealing against the movable guidewire or against itself. An additional variation of the invention includes a non-removable guidewire situated in the catheter body in such a way to provide or add stiffness to the otherwise flexible distal section of the catheter during a procedure. An enhanced strain relief transition joint between significantly stiffer proximal section and the more flexible distal section is provided. Finally, methods of using the inventive balloon catheter are also shown. The balloon is preferably produced of one or more materials that are resistant to components of chemical vaso-occclusive compositions or are resistant to adherence to those compositions.
