A method of forming a braided tubular base body having an opening at an end thereof for an implantable medical device, said method including:

• providing a plurality of form elements at one end region of a braiding head, said braiding head having a central axis (CA), and said form elements being disposed in a first arrangement around said central axis (CA),
• providing a plurality of pairs of first-stage wires;
• providing a plurality of second-stage wires;
• forming a plurality of groups of first-stage apices by
• hooking a pair of said plurality of pairs of said first-stage wires over a first form element and another pair of said plurality of pairs of said first-stage wires over a second form element adjacent to said first form element;
• forming a plurality of second-stage apices by
• hooking each of said second-stage wires over a different pair of said adjacent first and second form elements;
• and subsequently braiding said first and second-stage wires to said tubular base body.
