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: 9039715Abstract: A retrieval apparatus for entrapping and retaining an object located in a body for its extraction therefrom is described. The retrieval apparatus includes a snare and a snare control assembly. The snare has a proximal section and a distal section, and comprises a plurality of filaments extending from a proximal end of the proximal section towards the distal section, and then returning to the proximal end to form a plurality of loops. In the deployed state, the loops are interlaced to each other within the proximal section and are free and not interleaved within the distal section. Segments of the filaments of the distal section are bent with respect to segments of the filaments of the proximal section such that the retrieval snare in the contracted, state forms a hollow cavity extending from die distal section towards the proximal section.Type: GrantFiled: May 21, 2013Date of Patent: May 26, 2015Assignee: Great Aspirations Ltd.Inventors: Valery Diamant, Chaim Lotan, Haim Danenberg

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

Publication number: 20070043434Abstract: A biodegradable stent is comprised of a stereocomplex of polylactide enantiomers. The unique characteristics of stereocomplex polymers allows for the stent to have variable material characteristics along its length, while retaining uniform geometry. Thus, the stent is designed to be flexible upon insertion through the blood vessels while still retaining its rigidity and support upon expansion within the vessel. Furthermore, the material characteristics can be manipulated such that high strengths are possible even with small thicknesses of struts within the stent.Type: ApplicationFiled: August 18, 2005Publication date: February 22, 2007Inventors: David Meerkin, Abraham Domb, Chaim Lotan
