When expanding coat the non adjusted type balloon which accompanies the adjusted type higher stratum of society in order to protect sutento which is done

摘要

Organism compatibility and/or in order to minimize the possibility of the damage of sutentokoteingu which contains the remedy substance, the adjusted type elastic wrapping is offered above layer between non adjusted type sutento extended balloon and non extended sutento, this is locked on the balloon by the reduction which is locked. This sutento detention assembly is installed in the catheter, this is operated to the desirable detention region via the body of the patient, in order after that to expand sutento to desirable diameter, is expanded. When expanding, the adjusted type elastic material between sutento and the non adjusted type balloon is due to the perforation which for example sutento pulls up in addition to obstructing the fact that the damage by the non adjusted type balloon to sutentokoteingu is induced, disassembly of the non adjusted type balloon is prevented. The non adjusted type sutento extended balloon and the adjusted type elastic wrapping which do not expand are pulled out from the body of the patient next, sutento which is arranged, as for the coating in while the substantially it is intact, remains desirable transplantation region.
