Patent number: 8317851Abstract: An intravascular stent especially suited for implanting in curved arterial portions. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The triangular cells are adapted to provide radial support, and also to provide longitudinal flexibility after expansion. The triangular cells provide increased coverage of a vessel wall. The stent can have different portions adapted to optimize radial support or to optimize longitudinal flexibility. The stent can be adapted to prevent flaring of portions of the stent during insertion.Type: GrantFiled: March 31, 2006Date of Patent: November 27, 2012Assignee: Medinol Ltd.Inventors: Jacob Richter, Gregory Pinchasik

Publication number: 20120283817Abstract: An expandable helical stent is provided, wherein the stent may be formed of an amorphous metal alloy or other non-amorphous metal with a securement. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristic particular to that stent. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other to maintain the tubular shape of the helically coiled stent and prevent the polymer layer from sagging at any point between cycles of the coils.Type: ApplicationFiled: May 9, 2012Publication date: November 8, 2012Applicant: MEDINOL, LTD.Inventor: Jacob RICHTER

Patent number: 8202312Abstract: An intravascular stent especially suited for implanting in curved arterial portion. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The cells are adapted to provide radial support, and also provide longitudinal flexibility after expansion. The cells also provide increase coverage of a vessel wall. The stent has a reduced crimped profile due to the differing lengths of adjacent structural members within the cells, resulting in loops which are not aligned around the circumference of the stent. Also, this stent may contain a second type of square cells, which are adapted predominately to minimize flaring of the stent ends and to provide additional stiffness.Type: GrantFiled: March 5, 2008Date of Patent: June 19, 2012Assignee: Medinol Ltd.Inventor: Jacob Richter

Patent number: 8202280Abstract: The present invention relates to a device for the non-surgical clipping of aneurysms. The invention also includes methods of use to treat aneurysms, including intracranial aneurysms. The aneurysm is clipped by positioning a wire comprising a shape memory alloy, pre-set to a mutually twisted conformation, on opposite sides of the neck of the aneurysm and causing the wires to twist around each other. Thus, the aneurysm neck is substantially closed. The resulting thrombosis in the aneurysm further excludes the aneurysm from blood flow and pressure.Type: GrantFiled: August 13, 2009Date of Patent: June 19, 2012Assignee: Zuli Holdings Ltd.Inventor: Jacob Richter

Patent number: 7998193Abstract: An intravascular stent especially suited for implanting in curved arterial portions or ostial regions. The stent can include an end region which is fabricated to have a greater radial strength than the remaining axial length of the stent. Such a stent is particularly suited for use in ostial regions, which require greater support near the end of the stent. The stent alternatively can include sections adjacent the end of the stent with greater bending flexibility than the remaining axial length of the stent. Such a stent is particularly suited for use in curved arteries. The stent can also be constructed with an end that has greater radial strength and sections adjacent the end with greater bending flexibility. Such a stent prevents flaring of the stent end during insertion.Type: GrantFiled: May 10, 2010Date of Patent: August 16, 2011Assignee: Medinol Ltd.Inventor: Jacob Richter

Publication number: 20110196396Abstract: An attachment mechanism and method for attaching or coupling a guide wire to a catheter for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The attachment mechanism generates friction forces against the guide wire to couple the guide wire to a catheter, which design permits a greater force to be used on the guide wire during a re-canalization procedure. The invention also encompasses use of the attachment mechanism in conjunction with active catheters, which have vibration-generating means to oscillate the distal end of the catheter or a component in the distal end of the catheter, to add vibration motion, preferably axial vibration motion, to the increased force that may be applied to the guide wire for purposes of penetrating an occlusion. The methods of the invention relate to methods of attaching the guide wire to the catheter and methods of treating a vessel having a partial or total occlusion.Type: ApplicationFiled: February 8, 2011Publication date: August 11, 2011Applicant: OSCILLON LTD.Inventors: Jacob RICHTER, Amir PANSKY, Gal DEMER
