Abstract: The invention relates to an aspiration catheter for the extraction of thrombotic material from blood vessels, with a first and a second lumen, wherein the first lumen is distally provided with an aspiration opening and the second lumen of smaller cross section than the first lumen and extending coaxially in the distal region of the first lumen being provided with a lateral as well as distally located opening, said lateral opening reaching through the wall of the catheter. Within the first lumen a stabilization wire is movably arranged which terminates distally of the lateral opening of the second lumen but proximally of the aspiration opening of the first lumen.

Abstract: The invention relates to an aspiration catheter (1) for the extraction of thrombotic material from blood vessels, with a first (3) and a second lumen (6), wherein the first lumen (3) is distally provided with an aspiration opening (5) and the second lumen (6) of smaller cross section than the first lumen (3) and extending coaxially in the distal region (2) of the first lumen (3) being provided with a lateral (7) as well as distally located opening (8), said lateral opening (7) reaching through the wall of the catheter. Within the first lumen (3) a stabilization wire (11) is movably arranged which terminates distally of the lateral opening (7) of the second lumen (6) but proximally of the aspiration opening (5) of the first lumen (3).

Abstract: The invention relates to an aspiration catheter for the extraction of thrombotic maternal from blood vessels. The catheter has a first and a second lumen, the first lumen being distally provided with an aspiration opening and the second lumen having a smaller cross section than the first lumen and extending coaxially in the distal region of the first lumen. The second lumen is provided with a lateral as well as a distally located opening, the lateral opening reaching through the wall of the catheter. Within the first lumen a stabilization wire is movably arranged which terminates distally of the lateral opening of the second lumen but proximally of the aspiration opening of the first lumen.

Abstract: The invention relates to a balloon catheter with a catheter body (1) and with a balloon (2), wherein the balloon (2) is arranged along part of the length of the balloon catheter and can be expanded by delivery of a pressure medium through a delivery line (3). The balloon catheter is characterized in that the outside of the balloon (2) has a multiplicity of punctiform or groove-shaped depressions (4). These improve the application of forces to a vascular wall or stent surrounding the balloon (2). Moreover, in the case of balloons (2) coated with a medicament, the adherence of the medicament is strengthened.
