Embodiment approach

[0084] According to a preferred embodiment, said second pumping device 51 is adapted to deliver a pharmacological fluid 50 to said catheter shaft 20 . The second pumping means 51 is thus adapted to administer the pharmacological fluid 50 in the second part 44 of the isolated volume 40 . According to one embodiment, said second pumping device 51 is also adapted to pump a second fluid 50 from said catheter shaft 20 .

[0085] In this manner, the catheter handle 10 delivers a predetermined volume of pharmacological fluid 50 and At the same time, an equal predetermined volume of the first fluid 30 is sucked.

[0086] When in the operative state, the catheter shaft 20 is inserted into the vessel lumen 3 of the blood vessel 2, such as a varicose vein, and the at least one inflatable balloon 41 is fitted to the catheter shaft at the first shaft opening 24 20 on.

[0087] According to one embodiment, said at least two occlusion elements 42, 43 consist of two further inflatable ball...

Abstract

A vascular catheter (1) comprising a catheter shaft (20) having a distal end, a proximal end (14), a handle (10), at least two occlusion elements (42, 43) adapted to isolate an volume (40) of the blood vessel (2), an expandable balloon (41), between the two occlusion elements (42, 43); the catheter shaft (20) comprises a first hole (24) which opens into the expandable balloon (41); the catheter handle (10) comprises a first pumping device (31) associated with the first path and with a first tank (32) containing a first fluid (30); the catheter handle (10) comprises a second pumping device (51) associated with the second path and with a second tank (52) containing a second fluid (50); wherein the catheter handle (20) comprises a synchronization device (60) connectable both to the first and to the second pumping device (31, 51).

Description

technical field [0001] The invention relates to a vascular catheter. [0002] The vascular catheter of the present invention is particularly suitable for targeted local drug treatment. [0003] The present invention relates to a method. Background technique [0004] It is well known in clinical practice to introduce catheter shafts into the lumen of human blood vessels. [0005] In the case of arterial treatment (angioplasty), stents are usually implanted through vascular catheters in areas of arteries where the cross-section has been reduced by the accumulation of lipid plaques to restore the original diameter of the arteries by the mechanical action exerted by the stents, which are mounted on An inflatable balloon on the catheter shaft is inflated. It is also known to remove blockages in arteries by using devices adapted to treat plaques by pulsatile ultrasound excitation to crush vein-clogging substances in the body, especially when rich in calcium. [0006] Undesirab...
