BRAIDING CLOSURE HAVING REPETITIVE ENLARGED SEGMENTS SEPARATED BY JUNCTION AREAS Russian patent published in 2012 - IPC A61M29/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. A method for manufacturing of a device involves braiding of shape memory metallic fibres in a tubular metal lath to make a braided configuration. A lath end is fixed to prevent untwisting. The lath is arranged in or on a moulding structure of a first preset shape containing a number of enlarged spherical or ovaloid segments chained by intermediate links. The moulding structure is heated to higher temperature for a period of time sufficient for heat shrinkage of the lath in the first preset shape for keeping the first preset shape when the medical device is found in a relaxed condition. The metal lath of the first preset shape is modelled into a second preset shape by rolling up to keep the second preset shape when said device is found in a relaxed condition. What is disclosed is a device produced by this method.

EFFECT: decreased press-through efforts and increased thrombus formation rate.
