Problems solved by technology

Catheters with blood pumps have likewise been developed; however, they have proven to be complex and expensive, while the volume of blood delivered is always still small and there is also the risk of blood damage

Embodiment Construction

[0036] figure 1 A first embodiment of the invention is shown, in which case the (conventional) catheter is not shown in the figure.

[0037] The guide wire 1 with its distal end 6 and the supply hose 2 are shown, which are used to pressurize the balloon 3 by means of a hydraulic pump through a catheter, not shown. The supply hose 2 is closed at its distal end 7 .

[0038]The inflation balloon 3 is designed in the shape of a tube and provides an inner channel or cavity 5 which, in particular when the balloon is inflated, remains empty and is permeable for body fluids. The wall of the hose airbag 3 is made up of a number of hose parts 4 (4a, 4b...4g) which are in contact with each other. Each hose part 4 starts from the supply hose 2 and is connected thereto via connections 8 (8a, 8b...8g) in such a way that pressure can be applied thereto The loop extends back to the supply hose 2, but is not connected to the supply hose 2 at its corresponding other end, but is placed dead-e...

Abstract

The invention relates to a balloon dilatation catheter, in particular for percutaneous transluminal coronary angioplasty (PTCA), with a guide wire (1), with a supply tube (2) which extends parallel to the guide wire (1) and is used for inflating a dilatation balloon (3), and with the dilatation balloon (3) arranged in the distal area of the supply tube (2), said dilatation balloon (3) being of tubular design with a wall made up of a multiplicity of mutually contiguous tube segments (4), of which at least one is attached to the supply tube (2).

Description

technical field [0001] The present invention relates to a balloon dilatation catheter, especially for percutaneous transluminal coronary angioplasty (PTCA), comprising a guide wire, a supply hose extending parallel to the guide wire to inflate a dilation balloon and supplying An inflatable balloon is provided in the region of the distal end of the hose. Background technique [0002] The balloon dilatation catheter of the invention is primarily used for percutaneous transluminal coronary angioplasty (PCTA), but can also be used for other, in particular peripheral, vessel dilation. It is also possible to use it in other body cavities. [0003] Balloon dilatation catheters are often used to treat contractures, stenosis, or narrowing of various parts of the body. Such balloon catheters are used, for example, in percutaneous transluminal angioplasty (PTA) and in particular in the coronary area (PTCA), where they are used to eliminate narrowing of blood vessels. For this purpos...
