INTRACORPORAL LITOTRIPSY PROCEDURE Russian patent published in 2009 - IPC A61B18/12 A61B17/225 

FIELD: medicine.

SUBSTANCE: within intracorporal lithotripsy, fragmented concrement is approached with a probe supplied with electrodes connected through high-voltage pulse generators. When the specified pulses are supplied to electrodes, spark discharge is formed in-between with energy release thus causing concrement fragmentation. Besides method involves that at least one electrode is brought in direct electric contact with specified concrement so that the digit channel is formed sufficient enough to generate shock waves and voltages exceeding concrement material strength. The lateral peripheral surface of distal end if each electrode is covered with nonrigid insulating coating made of nonconductive material along the full length of lateral peripheral surface, except for fore limb.

EFFECT: easy and fast destruction with simultaneous capturing and holding fragmented calculus during the procedure and probability to reduce injury rate of adjacent organism tissues during treatment.
