Movable connection for heart valve implant has opening in one sheet engaged by slits in edges of corner of second sheet

摘要

The movable connection for individual sheets has a cut out (12) in at least one sheet (1). The other sheet (2) has an opposing edge with a pair of slits (22) and which is sufficiently elastic that the gap between the slits can be reduced so that the edge can be placed in the cut out in the first sheet. The slits then engage the edge (13) of the cut out in the first sheet. Claims include a method for joining sheets using the connection.
