Abstract:
A catheter device for the treatment of a vessel carrying body fluid, comprising an inner occlusion catheter, having a first tubular shaft with a proximal end and a distal end, a distal occlusion balloon disposed at the distal end of the first tubular shaft and an inflation lumen extending through the first tubular shaft between a proximal entry at the proximal end and a distal exit inside the distal occlusion balloon, and an outer treatment catheter, having a second tubular shaft with a central lumen extending therethrough for coaxial reception of the first occlusion catheter, and being longitudinally displaceable with respect to the first occlusion catheter, the first tubular shaft inflation lumen having a proximal entry seal having an outside dimension small enough to fit within the central lumen for advancing and withdrawing the treatment catheter onto and from, the inner occlusion catheter.
