title: [The construction and operation of an intravasal deflectable cavoportal puncture catheter. An animal experimental study].
abstract: Principle and construction of a cavoportal catheter for the intravasal puncture of the portal stem from the caval lumen is presented. This is a prerequisite in the performance of a nonanatomical, extrahepatic communication between these vessels. Experiences in animal trials confirm the proper functioning of this special catheter prototype.
