Patent number: 9498237Abstract: 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.Type: GrantFiled: June 6, 2014Date of Patent: November 22, 2016Assignee: LITHOTECH MEDICAL LTDInventors: Valery Diamant, Alexey Dutov, Vladimir Chernenko, Marat Lerner

Patent number: 9271746Abstract: A retrieval snare for entrapping and retaining a foreign object located in a body and a method for manufacturing of the snare are provided. The snare comprises a structure having a proximal portion and a distal portion and includes a plurality of filaments. The filaments extend from an end of the proximal portion towards the distal portion and return to the end of the proximal portion to form a plurality of loops. The loops are not interconnected at the distal portion, but each side of each loop are connected to a side of an adjacent loop in the proximal portion at more than one point, thereby providing structural rigidity and dilatation ability to the snare.Type: GrantFiled: October 2, 2007Date of Patent: March 1, 2016Assignees: COOK MEDICAL TECHNOLOGIES LLC, LITHOTECH MEDICAL LTD.Inventors: Valery Diamant, Nadezka Yasko, Kevin L.
