Patent number: 9743980Abstract: A method and a system for assisting a wire guide to cross obstructed ducts in mammalian body are described. The method and system is based on applying pulsed energy to occlusion obstructing the duct. The pulsed energy is applied by means of an auxiliary probe. The auxiliary probe is relatively displaceable with respect to the wire guide along a lumen provided within the probe. The distal region of the probe is provided with enhanced flexibility comparing with the reminder portion of the probe.Type: GrantFiled: February 24, 2010Date of Patent: August 29, 2017Assignee: Safepass Vascular LtdInventors: Valery Diamant, Vladimir Chernenko, Marat Lerner, Ludmila Ivanova, Alexey Dutov, Nadezda Yasko

Patent number: 9526646Abstract: A system for delivering and placement of a medical prosthesis into an ostium of a tract system of an organism is described. The system comprises a stent delivery device that includes a delivery catheter having one or more lumens extending between proximal and distal ends. The stent delivery device also includes an inflatable balloon mounted on the distal end of the delivery catheter for expanding and deploying the medical prosthesis placed on the balloon, and a stent deployment site locator configured for locating an exact place for positioning the medical prosthesis. The deployment site locator comprises an expandable flexible structure including a plurality of filament elements interconnected between a locator proximal end and a locator distal end; thereby forming a unitary structure. The filaments can extend from a locator proximal end towards a locator distal end and then return after winding to the proximal end to form a plurality of filament loops.Type: GrantFiled: December 3, 2008Date of Patent: December 27, 2016Assignee: MEDKARDIA LTD.Inventors: Valery Diamant, Nadezda Yasko, Boris Varshitsky, Nachum Borivker, Chaim Lotan

Patent number: 8992553Abstract: A cutting balloon assembly and a method for fabrication of the assembly is described. The cutting balloon assembly comprises a delivery catheter, an expandable balloon mounted on the catheter distal end, and a scoring mesh disposed around the expandable balloon. The scoring mesh comprises interlacing filaments that extend from a mesh proximal end towards a mesh distal end, form distal filament loops at said mesh distal end, and then return to the mesh proximal end. At least a part of the interlacing filaments forms one or more permanent links with neighboring filaments between the mesh proximal end and the mesh distal end.Type: GrantFiled: October 1, 2009Date of Patent: March 31, 2015Assignee: CardionitiInventors: Valery Diamant, Haim Danenberg, Chaim Lotan, Nadezda Yasko

Patent number: 8926630Abstract: 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.Type: GrantFiled: November 20, 2012Date of Patent: January 6, 2015Assignee: Lithotech Medical Ltd.Inventors: Valery Diamant, Nadezda Yasko, Aleksei Dutov, Vladimir Chernenko, Marat Lerner

Patent number: 8771299Abstract: A method for fabrication of a cutting balloon assembly is described. The method includes providing a predetermined number of filaments having predetermined properties, diameter and length and fabricating a scoring mesh on a weaving jig having a plurality of pins disposed circumferentially about the jig's surface. The fabrication of the scoring mesh includes placing the filaments between the pins and interlacing the filaments to form a scoring mesh by interweaving and intertwining at least a part of filament to form one or more permanent links with neighboring filaments. The fabrication of the scoring mesh also includes forming distal and proximal filament loops that protrude from the mesh distal and proximal ends, respectfully. The scoring mesh is mounted on an expandable balloon mounted on a distal end of a delivery catheter.Type: GrantFiled: May 23, 2012Date of Patent: July 8, 2014Assignee: CardioNiTiInventors: Valery Diamant, Haim Danenberg, Chaim Lotan, Nadezda Yasko

Patent number: 7731722Abstract: A retrieval device for use in renal, biliary, vascular or other systems of a body includes a collapsible basket in a narrow sheath. A surgeon advances the device beyond an object to be removed from a body, such as a kidneystone, a gallstone, or a thrombus. The surgeon then retracts the sheath or advances the basket from the sheath. The basket deploys only to one side of the sheath. In some embodiments, the periphery of the basket has a flex point to enable the basket to easily collapse into the sheath. If the sheath is adjacent a body vessel, such as a blood vessel or a ureter, the sheath remains adjacent the wall, while the device deploys in such a manner as to seal against the walls of the vessel and block the flow of fragments, emboli, thrombi, or other undesirable objects.Type: GrantFiled: July 28, 2004Date of Patent: June 8, 2010Assignees: Vance Products Incorporated, Lithotech Medical, LimitedInventors: Shay Lavelle, Marvin O.
