Abstract: The device comprises a retaining body that retains a medical implant in an insertion device and includes a proximal end that is distant from a distal end of the insertion device in the state of use, a distal end that faces the distal end of the insertion device in the state of use, and two segments (16, 18) that radially delimit a space (20) extending between one of insertion elements (52, 54) and each of the segments. The implant comprises a retaining element (10) at its proximal end. A region of the retaining element is inserted into the space in a direction of insertion (56). The device comprises a retaining body that retains a medical implant in an insertion device and includes a proximal end that is distant from a distal end of the insertion device in the state of use, a distal end that faces the distal end of the insertion device in the state of use, and two segments (16, 18) that radially delimit a space (20) extending between one of insertion elements (52, 54) and each of the segments. The implant comprises a retaining element (10) at its proximal end. The retaining body interacts with the retaining element. A region of the retaining element is inserted into the space in a direction of insertion (56) and is withdrawn from the space against the direction of insertion upon interaction with the retaining body. The implant is first released at a distal end of the implant by a relative motion between the first insertion element and the second insertion element in the direction of insertion in the insertion device. The space is formed at one of the proximal end of the retaining body or at the distal end of the retaining body. The retaining body is fastened to one of a distal end and a proximal end of one of the insertion elements and adhered to an inner insertion element by a UV-curable adhesive. The segments are formed on a same component or two different components and arranged in a region of a component that extends in a circumferential direction about one of the insertion elements. The insertion device is provided for inserting the medical implant. The insertion device further comprises a stopper that is operative to limit motion of the implant in one of a direction of a proximal end of the insertion device or in a direction of the distal end of the insertion device, and induces ejection of the implant. The medical implant comprises: a base body; and the retaining element configured for interaction with the retaining body of the release device. The retaining element has a change in direction that forms a total angle of more than 90[deg] relative to a region of the base body that extends parallel to an inner axis of the base body, and is oriented in the radial direction with respect to the inner axis. The base body has a basic structure. The retaining element comprises the basic structure of the base body by more than 50%. The retaining element has a length that is greater than a thickness of the segments of the retaining body. The release device is configured for connecting to the medical implant using the retaining body in the insertion device by: placing the proximal end of the implant, against the direction of insertion, at one of the insertion elements, so that the proximal end of the implant is arranged proximally with respect to the retaining body; moving the proximal end of the implant in the direction of insertion so that the region of the retaining element of the proximal end of the implant is inserted in the direction of insertion into the space; and placing the retaining body comprising the implant in one of the insertion elements. An independent claim is included for a method for connecting a release device.
