APPARATUS OF VERTEBRA BALLOON KYPHOPLASTY (VERSIONS) Russian patent published in 2011 - IPC A61B17/70 A61F2/44 A61M25/10 A61M29/02 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. According to the first and second versions apparatus contains device for pumping bone-substituting material into vertebra body and bearing catheter tube with canal and connected with it supercharger of liquid under pressure into hermetically fixed in distal end of bearing catheter tube dilatation balloon from elastic stretchable material. According to the first version apparatus includes electric magnet with output to source of alternating current and made with possibility to be installed on patient's body along spine. Into distal part of dilatation balloon introduced are ferromagnetic elements. Electric magnet is made with possibility to create alternating magnetic field and influence with it on ferromagnetic elements in order to provide jerk-oscillatory movements in distal part of dilatation balloon. According to the second version apparatus has implementation of dilatation balloon with introduced into proximal part frame-like stopper of unfolding balloon from non-stretchable material. Liquid supercharger has hydropulse modulator, which has output to generator of electric pulses. Hydropulse modulator is made with possibility to create hydropulses for performing by them influence on dilatation balloon and creation of translational jerk-oscillatory movements in distal part of the latter.

EFFECT: inventions ensure treatment of compression fractures of vertebra bodies due to delicate impact on bone spongy tissue by soft, translational, jerk, oscillatory movements of distal part of dilatation balloon, which make it possible to overcome compression, impeding with complete restoration of vertebra body height, contributes to its smoothing, as well as denser "packing" of vertebra fragments around formed cavity.
