METHOD FOR DRAINING INTRACEREBRAL ISOLATED LIQUOR CYSTS Russian patent published in 2006 - IPC A61M27/00 

FIELD: medicine, neurosurgery.

SUBSTANCE: one should form a cutting foramen, make a drainage into cystic cavity, fix it and withdraw its distal end beyond cystic limits. Moreover, on installing proximal end of drainage in cystic cavity its distal end should be curved, closed to perform longitudinal incision of a wall and direct it into subarachnoidal space. Drainage should be fixed with a coupling installed at a drainage at the level of a cutting foramen, and a clamp made out of shape-memory metal. A clamp should be installed so, that one of its pedicle be between coupling wall and drainage, and the second - between the bone and external surface of dura mater. The innovation enables to decrease traumatism of surgical access due to excluding liquor flow and reliable drainage fixation.

EFFECT: higher efficiency of draining.
