MEDICAL CATHETER FOR HYPOTHERMIC TREATMENT, TREATMENT SYSTEM WITH SUCH A CATHETER, AND PRODUCTION METHOD

摘要

The application relates to a medical catheter for hypothermic treatment, with a catheter tube (10), which has at least one through-channel (11) and at least two temperature control channels (12, 13), and with at least one heat exchange element (14), in particular an expandable balloon, which is arranged in a distal catheter portion (15) of the catheter tube (10) and is fluidically connected to the temperature control channels (12, 13) in such a way that a temperature control circuit is formed. The application is characterized in that the catheter tube (10) has a smaller external diameter in the distal catheter portion (16) than in a proximal catheter portion (15).

主权项

1. A medical catheter for hypothermic treatment; the medical catheter comprising:
a catheter tube comprising
a proximal catheter portion and a distal catheter portion,a first outside diameter in the distal catheter portion and a second outside diameter in the proximal catheter portion, the first outside diameter being smaller than the second outside diameter,a through-lumen, andat least two temperature-regulating lumens; a heat-exchanger element disposed in the distal catheter portion and being in fluid communication with the at least two temperature-regulating lumens; and a temperature-regulating circuit comprising a heat-exchanger element and the at least two temperature-regulating lumens.
