Percutaneous catheter for infusing drugs into a human body

摘要

The catheter (1) comprises two separate ducts in its interior and for its entire length, said ducts being a first duct (3) for the passage of the drug to be infused and a second duct (4) for the passage of a hardening fluid introduced from outside the catheter; a hole (5) through which the drug is to be released may be situated in any convenient longitudinal position in the first duct (3), while the second duct (4) is provided with an aperture (6) from which a mass of the hardening fluid may pass into the artery (15) to set the catheter in a desired position and permanently maintain it there. <IMAGE>
