Publication number: 20230414388Abstract: A flow modifying apparatus may include a plurality of struts coupled together to form a radially expandable frame having a proximal end and a distal end. The proximal and distal ends may be radially expandable into expanded proximal and distal ends. A reduced diameter portion of the expandable frame may be disposed between the expanded proximal and distal ends and the reduced diameter portion may comprise a fluid flow through passage. A cover may be disposed over at least a portion of the radially expandable frame. The reduced diameter portion modifies fluid flow therethrough immediately upon implantation thereof and forms a pressure gradient between the inflow end and the reduced diameter portion.Type: ApplicationFiled: June 26, 2023Publication date: December 28, 2023Applicant: NEOVASC MEDICAL LTD.Inventors: Keith Alan JACKSON, Colin Alexander NYULI, Shmuel BANAI, Fredericus Antonius COLEN

Publication number: 20130317593Abstract: A method for deploying an expandable implant in a body passage of varying diameter includes selecting a balloon having a radial dimension that varies, when the balloon is inflated, in accordance with the varying diameter of the body passage. The balloon is inserted, in a deflated state, into the body passage, with the expandable implant fitted radially around the balloon. The balloon is inflated so as to cause the implant to open, responsively to the varying radial dimension of the balloon, into an expanded shape that approximately matches the varying diameter of the body passage, thus anchoring the implant in the body passage.Type: ApplicationFiled: November 12, 2012Publication date: November 28, 2013Applicant: NEOVASC MEDICAL LTD.Inventors: Shmuel Ben-Muvhar, Ilan Shalev, Jonathan Tsehori, Nissim Darvish

Patent number: 8556954Abstract: Methods of using flow reducing implants for treatment of abnormal growths in the body are described. In embodiments of the claimed subject matter, a source blood vessel feeding the abnormal growth is first determined, and a flow reducing implant is then inserted into the source blood vessel to reduce the blood flow through the source blood vessel. The flow reducing implant includes at least one flared section for contacting a blood vessel wall, and at least one narrowed section defining a flow passage. Anchor tabs that lie generally in a plane of the flared section may also be employed.Type: GrantFiled: October 21, 2009Date of Patent: October 15, 2013Assignee: Neovasc Medical LtdInventors: Shmuel Ben Muvhar, Ilan Shalev, Jonathan Tsehori, Nissim Darvish
