Embodiment Construction

[0032] refer to Figure 1 to Figure 17 , the basic assembly of the delivery catheter arrangement 10 according to the invention will first be explained. as especially in Figure 1 to Figure 4 As can be clearly seen in FIG. 2 , the delivery catheter arrangement 10 comprises a delivery catheter 12 known per se, which has an outer cannula 16 and a fine stylet 14 which is movably arranged in the outer cannula 16 . Outer sleeve 16 is only partially in figure 1 described in , and not in Figure 2 to Figure 4 described in. especially in Figure 10 and Figure 12 A complete illustration of the delivery catheter 12 is found in .

[0033] An inner stent (not shown) is disposed at the distal end D of the delivery catheter 12 , in a compressed state between the stylet 14 and the outer cannula 16 . By retraction of the overtube 16, the inner stent can be released and expanded in the patient's hollow organ.

[0034] Adapter 22 is disposed at the end piece of stylet 14 at proximal end...

Abstract

The invention relates to a release device for actuating a delivery catheter which comprises an outer casing and a mandrin which is movably arranged in the outer casing. The release device comprises an elongated handle, a fixing seat which is arranged on the handle and which is designed to fix a proximal end piece of the mandrin on the handle in a stationary manner relative to the longitudinal axis of the handle, and a guide which is formed on the handle and which is designed to receive an actuating element that is arranged on the proximal end region of the outer casing in a movable manner with respect to the longitudinal axis of the handle and with respect to the mandrin. The handle comprises an elongated base part and an adjusting part which is connected to the base part and which can be adjusted along the longitudinal axis of the base part. The adjusting part can be switched between an adjusting state in which the adjusting part is held on the base part in an axially movable manner in order to change the length of the guide and a locking state in which the adjusting part is locked on the base part at least in an axial manner.

Description

technical field [0001] The present invention relates to a release device for driving a delivery catheter. Background technique [0002] The present invention relates to a release device for actuating a delivery catheter comprising an overtube and a thin stylet displaceably arranged in the overtube, the release device comprising an elongate handle arranged on the handle A fastening receiver at the handle and a guide configured at the handle, the fastening receiver configured to immovably determine the proximal end of the stylet relative to the longitudinal axis of the handle at the handle , the guide configured to movably receive a drive element disposed relative to the longitudinal axis of the handle and relative to a proximal region of an outer sleeve of the handle. [0003] The positional expressions "distal" and "proximal" relate to the operator of the release device and / or the delivery catheter, respectively. [0004] Devices for introducing stents, drainage tubes or t...
