摘要:
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.
摘要:
A method and a system for destruction of an undesirable formation in a mammalian body are described. The invention is based on inserting a probe into mammalian body; said probe is electrically connectable to a control unit and upon bringing the probe in physical contact with the formation supplying pulses of energy from the control unit to the probe in order to destroy the formation. The invention further comprises counting amount of pulses being supplied to the probe and establishing a remaining service life of the probe by subtracting the amount of pulses being supplied to the probe from an amount of pulses corresponding to initial service life of the probe. The treatment session is automatically terminates as soon as amount of pulses being supplied to the probe approaches at least a fraction of the established remaining service life of the probe. The established remaining service life of the probe is stored for new treatment session. Delivery of pulses automatically terminates when the remaining service life is exhausted and use of such probe becomes impossible.
