The balloon catheter has a catheter pipe (10) and a hydraulically expandable balloon (14) on a balloon support (13). Between the catheter pipe (10) and the balloon support (13) there is a small-diameter pump (16) which takes blood in through lateral inlets (21) and pumps it through the tubular balloon support (13). The pump (16) is driven via a flexible shaft (23) running through the catheter pipe (10) or by a directly integrated micromotor.

Ce cathéter à ballonnet présente un tuyau flexible (10) et un ballonnet (14) expansible de façon hydraulique et reposant sur un support de ballonnet (13). Une pompe (16) de faible diamètre, placée entre le tuyau flexible (10) et le support de ballonnet (13) aspire le sang par des ouvertures d'admission latérales (21) pour le pomper ensuite à travers le support de ballonnet (13) tubulaire. La pompe (16) est entraînée par un arbre flexible (23) qui s'étend à travers le tuyau flexible (10), ou par un micromoteur directement intégré.
