Abstract

Abstract This invention relates to a catheter comprising a tube-like basic body with a distal and a proximal end, wherein the catheter comprises an expandable filter element at the distal end and a device for reducing thrombi in size and removing them. The filter element is formed by a number of strip-shaped wall sections of the basic body defined in between longitudinal cuts evenly distributed around the circumference and furthermore comprises a means for moving the sections of the basic body positioned on either side of the wall sections towards each other in order to make the wall sections bend outwards.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 90 words
Catheter comprising a tube-like basic body with a distal and a proximal end, wherein the catheter comprises at the distal end an expandable filter element formed by a number of strip-shaped wall sections of the basic body defined in between longitudinal cuts evenly distributed around the circumference, and furthermore comprising a means for moving sections of the basic body situated on either side of the wall sections towards each other in order to make the wall sections bend outwards, and a device for reducing thrombi in size and removing them
Claim 2
Dependent Claim 47 words
Catheter as claimed in claim 1, wherein the thrombi reduction and discharge device comprises a jet nozzle connected with a pressure lumen inside the basic body pointing in the proximal direction and a discharge opening, formed opposite the jet nozzle, which is connected to a discharge lumen.
Claim 3
Dependent Claim 47 words
Catheter as claimed in claim 1, comprising an outer tube-like body and an inner tube-like body received inside it in a movable manner, which are connected to each other at their distal ends and wherein the strip-shaped wall sections have been formed in the outer tube-like body.
Claim 4
Dependent Claim 24 words
Catheter as claimed in claim 2 and 3, wherein the pressure lumen and the discharge lumen have been received inside the inner tube-like body.
Claim 5
Dependent Claim 28 words
Catheter as claimed in claim 4, wherein the jet nozzle and the discharge opening are positioned inside the longitudinal section of the catheter wherein the longitudinal cuts extend.
Claim 6
Dependent Claim 35 words
Catheter as claimed in one of the claims 2 - 5, wherein the jet nozzle has been positioned and dimensioned in relation to the discharge opening in such a way that they form an ejector.
