Abstract: A medical device and method for breaking a concretion in a body into smaller pieces and removing the pieces from the body are described. The device comprises a dilator sheath, a lithotripsy probe, a tubular member, and a retrieval basket. The dilator sheath adapted to penetrate into a passage of the body to reach the location where the concretion is located. The lithotripsy probe is configured for shattering the concretion into smaller pieces. The tubular member is mounted within the dilator sheath adapted to permit the lithotripsy probe to be inserted into the tubular member. The retrieval basket is coupled to the tubular member, and configured for entrapping the concretion and the smaller pieces for their extraction from the body. The retrieval basket comprises a structure constituted by a plurality of filaments extending from a basket proximal end towards a basket distal end, and then returning to the proximal end after forming a plurality of filament loops in the basket distal portion, and a plurality of filament strands at the basket proximal portion.

Abstract: Electro-impulse intracorporeal lithotripsy method comprises bringing electrodes of a probe in immediate electrical contact with the calculus and supplying to the electrodes very short high voltage impulses capable to ignite electrical spark discharge and establish a discharge channel within the bulk of the calculus. The channel goes through the calculus and creates tensile stresses, destroying the calculus.
