Abstract
The invention relates to a device for closing a vein juncture in the treatment of varicose veins including a catheter which can be inserted into a venous system and at the distal end of which an expandable balloon is arranged, a covering which is arranged circumferentially on the balloon and can be expanded by means of said balloon, wherein the proximal covering end is designed to be open, and at least one adhesion agent for acting on the expanded covering such that it adheres to a vein wall in order to close the vein juncture.
Claims19
A device for closing a vein juncture in the treatment of varicose veins, the device comprising:
- a catheter to be inserted into a venous system;
- an expandable balloon which is disposed at a distal end of the catheter, the expandable balloon being permanently attached to the catheter;
- a covering which is disposed circumferentially on the expandable balloon and configured to be expanded by said expandable balloon, the covering extending from a proximal covering end to a distal covering end, the proximal covering end being configured to be open, the covering being closed at the distal covering end, the covering on the expandable balloon having a maximum width of 0.5-1.5 cm in an expanded state, and an average thickness of at most 0.7 mm in a non-expanded state;
- and
- at least one adhesion agent configured to act on the covering when expanded such that the covering adheres to a vein wall in order to close the vein juncture,
- wherein the catheter includes:
- a first channel which fluidically connects a connection at a proximal end of the catheter to the expandable balloon, and
- a second channel which extends from an inlet opening at the proximal end of the catheter to an outlet opening at the distal end of the catheter and is configured to accommodate a guide wire.

A device for closing a vein juncture in treatment of varicose veins, the device comprising:
- a catheter configured to be inserted into a venous system;
- a balloon which is expandable and which is disposed at a distal end of the catheter;
- a covering which is disposed circumferentially on the balloon and configured to be expanded by said balloon, the covering extending from a proximal covering end to a distal covering end, the proximal covering end being configured to be open, and the distal covering end being designed to be closed;
- at least one adhesion agent configured to act on the covering when expanded such that the covering adheres to a vein wall in order to close the vein juncture;
- a first channel which fluidically connects a connection at the proximal end of the catheter to the balloon;
- and
- a second channel which extends from an inlet opening at the proximal end of the catheter to an outlet opening at the distal end of the catheter and is configured to accommodate a guide wire,
- wherein the outlet opening is arranged radially offset with respect to the balloon, so that the balloon with the covering is configured to be disposed laterally with respect to the guide wire when accommodated in the second channel, and
- the first channel and the second channel are attached to the catheter.
6 more elements
A device for closing a vein juncture in the treatment of varicose veins and for treating a vein leading to the vein juncture, the device comprising:
- a catheter configured to be inserted into a venous system;
- a first balloon which is expandable and which is disposed at a distal end of the catheter;
- a covering which is disposed circumferentially on the first balloon and is configured to be expanded by said first balloon, the covering extending from a proximal covering end to a distal covering end, and the proximal covering end being configured to be open;
- at least one adhesion agent configured to act on the covering when expanded such that the covering adheres to a vein wall in order to close the vein juncture;
- a feed channel with side openings through which a sclerosant is configured to be introduced into the vein;
- and
- a cutter configured to cut intima and media of the vein, the cutter extending along the longitudinal axis of the device, the cutter including a second balloon which is expandable and configured to cut, the side openings of the feed channel being disposed closer to a proximal end of the catheter than the second balloon.
