Abstract
A method for gripping the pericardium uses a device with an outer part and an inner part. The device is pushed through an incision towards the pericardium until an end of the device touches the pericardium or the heart or a layer arranged on the heart. Subsequently, the inner part is moved until at least one outer part end and/or an inner part end is arranged on the pericardium. The device for gripping the pericardium has an inner tube and an outer tube. The inner tube and the outer tube have end surfaces with different surface structures.
Claims14
A method for gripping the pericardium of
- a patient, comprising:
- providing a device having an outer part and an inner part,
- wherein the outer part includes an inner tube movably arranged in an outer tube,
- the inner tube having an inner tube diameter and an inner tube end with an inner tube end surface with a first surface structure;
- and
- the outer tube having an outer tube diameter, the outer tube diameter being larger than the inner tube diameter, and an outer tube end with an outer tube end surface with a second surface structure, the first surface structure and the second surface structure being formed differently;
- wherein the inner tube is movably arranged in the outer tube, wherein the inner tube is rotatably arranged in the outer tube;
- creating a body opening;
- advancing the device through the body opening in the direction of the pericardium;
- touching the pericardium, the heart or a layer arranged on the heart with at least one end of the device;
- moving the outer part until the outer tube end surface and the inner tube end surface are arranged flush with each other on the pericardium;
- moving the inner part within the inner tube;
- and
- gripping the pericardium by turning the inner tube in relation to the outer tube.

- an inner tube having an inner tube diameter and an inner tube end with an inner tube end surface with a first surface structure;
- an outer tube having an outer tube diameter, the outer tube diameter being larger than the inner tube diameter, and an outer tube end with an outer tube end surface with a second surface structure, the first surface structure and the second surface structure being formed differently;
- and
- an inner part, the inner part being movably arranged in the inner tube,
- wherein the inner tube is movably arranged in the outer tube,
- wherein the inner tube is rotatably arranged in the outer tube, and
- wherein gripping the pericardium is effected by arranging the outer tube end surface and the inner tube end surface flush with each other while touching the pericardium and turning the inner tube in relation to the outer tube.
