Catheter system for introducing an expandable heart valve stent into a patient's body, insertion system equipped with a catheter system, and medical device for treating heart valve defects

摘要

The present invention relates to a catheter system for introducing an expandable heart valve stent (150) into a patient's body. The catheter system comprises a seat portion composed of a first sleeve-like element (11) and a second sleeve-like element (21) for accommodating a collapsed stent (150), and the stent (150). A stent holder (115) releasably securing the sleeve tip (10), wherein the sleeve-like elements (11, 21) are movable relative to each other and relative to the stent holder (115). A catheter tip (10); and a catheter shaft (30) connecting the catheter tip (10) to a handle (70). The catheter shaft (30) is connected to the first sleeve-like element (31) connected to the first sleeve-like element (11), and to the second sleeve-like element (21). A second force transmitting means (41) having a distal end connectable to a second actuating means (81) of the above and a guide means (51) having a path extending therethrough, The first and second force transmission means (31, 41) are at least partially received in the path so as to be movable relative to the guide means (51) and are proximal to the guide means (51). The end terminates distal to the catheter tip (10). [Selection] Figure 1
