Insertion tool for a medical closure device for the sealing of an opening in a wall of a bodily organ, comprising a tamping force source adapted to deliver a first member to a position at the opening on one side of the wall subsequently to a second member being positioned at the opening on the opposite side of the wall. The tamping force source, which is energized prior to the tamping procedure, can be for example a spring, an elastic band or a pressurized gas container. A tamping spring can be compressed or extended upon loading. The tamping force source can be released in response to a manual operation or be triggered by retraction of the insertion tool.

The insertion tool according to claim 1, wherein energizing of the tamping force source is performed during manufacture of the insertion tool. 11. The insertion tool according to claim 1, wherein the tamping mechanism is adapted to bring together the first and second members on opposite sides of the wall by applying a tamping force to one of the first and second members while the other of the first and second members is retained in position. 12. The insertion tool according to claim 1, wherein the tamping force source is attached to an inside of the housing. 13. The insertion tool according to claim 1, wherein the tamping force source is a spring that is extended when energized and compressed upon actuation. 14. A medical device for closure of an opening in a wall of a bodily organ, comprising: a first member;a second member;a filament; andan insertion tool comprising a tamping mechanism adapted to bring together the first and second members on opposite sides of the wall, and a filament coupling device having a restraining member,wherein the tamping mechanism comprises a housing, a tamping member protruding from the housing, a fastener, and a tamping force source attached to the housing,wherein the tamping force source is adapted to be energized prior to initiation of a tamping procedure such that the energized tamping force source is configured to apply an application force to the tamping member while the tamping member is held in place by the fastener,wherein the tamping force source is adapted to advance the tamping member away from the housing after actuation during the tamping procedure by releasing the fastener from the tamping member, andwherein the restraining member is configured to hold on to the filament at an interior space of the housing during the tamping procedure and configured to release the filament upon actuation of a filament releasing mechanism. 15. The medical device according to claim 14, wherein the tamping force source, when energized, is adapted to deliver a set amount of tamping force when the fastener is released. 16. The medical device according to claim 14, wherein the tamping force source is a spring, which is extended or compressed upon energizing. 17. The medical device according to claim 14, wherein the bodily organ is a blood vessel or a septal defect. 18. The medical device according to claim 14, wherein energizing of the tamping force source is performable prior to insertion of one of the first and second members into the opening. 19. The medical device according to claim 14, wherein the tamping mechanism is adapted to bring together the first and second members on opposite sides of the wall by applying a tamping force to one of the first and second members while the other of the first and second members is retained in position. 20. The medical device according to claim 14, wherein the tamping force source is attached to an inside of the housing. 21. The medical device according to claim 14, wherein the tamping force source is a spring that is extended when energized and compressed upon actuation. 22. The medical device according to claim 14, wherein, prior to initiation of the tamping procedure, the tamping member is at a spaced distance from the first and second members.
