## Abstract

The present application relates to an insertion sleeve (2), in which a guide wire (3) extends in order to guide the insertion sleeve (2). A cavity (23) is formed in the sleeve wall (22), which cavity extends in parallel with a longitudinal direction of the insertion sleeve (2) over the whole length of the sleeve, wherein said cavity (23) accommodates the guide wire (3). In addition to the cavity (23) at least one control wire (4) is integrated into the sleeve wall (22), which at least one control wire is designed to cause a curvature of the insertion sleeve (2).

## Claims

### Claim 1

An endovascular insertion sleeve configured to receive a guide wire for guiding the insertion sleeve, the insertion sleeve comprising:
a central cavity formed in the insertion sleeve, the central cavity having a center that is coaxial with a center of the insertion sleeve, the central cavity having a circular cross-sectional profile; and
a second cavity formed in a wall of the insertion sleeve, wherein the second cavity extends parallel to a longitudinal direction of the insertion sleeve over an entire length of the insertion sleeve, wherein the second cavity is configured to receive the guide wire extending in the second cavity, wherein at least one control wire is integrated within the insertion sleeve, wherein the at least one control wire is configured to control a curvature of the insertion sleeve, and wherein the second cavity is positioned radially outward from the circular cross-sectional profile of the central cavity of the insertion sleeve throughout the entire length of the insertion sleeve.

### Claim 2 (depends on 1)

The insertion sleeve according to claim 1, wherein the second cavity is positioned entirely within the sleeve wall.

### Claim 3 (depends on 1)

The insertion sleeve according to claim 1, wherein the guide wire has a soft, flexible and proximally curved tip.

### Claim 4 (depends on 1)

The insertion sleeve according to claim 1, wherein the at least one control wire is configured to be shortened and/or lengthened to control the curvature of the insertion sleeve.

### Claim 5 (depends on 1)

The insertion sleeve according to claim 1, wherein an effective length of the at least one control wire is continuously adjustable or adjustable in predefined steps.

### Claim 6

A device for inserting an endovascular system into a blood vessel, comprising:
an insertion sleeve comprising:
a central cavity formed in the insertion sleeve, the central cavity having a center that is coaxial with a center of the insertion sleeve, the central cavity having a circular cross-sectional profile; and
a second cavity formed in a wall of the insertion sleeve, wherein the second cavity extends parallel to a longitudinal direction of the insertion sleeve over an entire length of the insertion sleeve, and wherein the second cavity is positioned radially outward from the circular cross-sectional profile of the central cavity of the insertion sleeve throughout the entire length of the insertion sleeve; and
a guide wire configured to extend within the second cavity of the insertion sleeve,
wherein at least one control wire is disposed in the insertion sleeve, and wherein the at least one control wire is configured to control a curvature of the insertion sleeve.

### Claim 7 (depends on 6)

The device according to claim 6, wherein the at least one control wire is connected to the insertion sleeve in a non-displaceable manner in a region of a distal end of the insertion sleeve.

### Claim 8 (depends on 6)

The device according to claim 6, wherein the at least one control wire extends along the insertion sleeve and ends proximally in a control device.

### Claim 9 (depends on 8)

The device according to claim 8, wherein the control device is configured to shorten and/or lengthen a section of the at least one control wire located in the insertion sleeve.

### Claim 10 (depends on 6)

The device according to claim 6, wherein the at least one control wire comprises a plurality of control wires comprising lengths configured to be adjustable relative to one another in a coordinated manner.

### Claim 11 (depends on 6)

The device according to claim 6, wherein an end section of the guide wire protrudes freely beyond a distal end of the insertion sleeve.
