The catheter system comprises an elongated catheter shaft 2 with a longitudinal lumen 4 extending therethrough and provided with a closure 6 in the vicinity of the distal end of the shaft. Inside the longitudinal lumen 4 is a removable wire 7 with a tip 14 providing a distally oriented push to closure 6. A balloon 8 is surrounding a portion of the distal area 3 of catheter shaft 2. A guidewire lumen 10 is formed in the distal area 3 of catheter shaft 2 with an entry 11 for the guidewire 12 at the distal end 5 of shaft 2 and an exit 13 for the guidewire 12 which is distal of the distal end 9 of balloon 8. The closure 6 of the longitudinal lumen 4 is distal of the exit 13 of the guidewire lumen 10 whereby the distal tip 14 of wire 7 provides the closure 6 with a push distal of the exit 13 of the guidewire lumen 10.
