Patent number: 10188516Abstract: A loading tool for withdrawing, crimping, and loading a stent-mounted valve into a delivery catheter, and for pushing the stent-mounted valve from the delivery catheter into a native heart valve orifice. The loading tool comprises at least one connector adapted for being removably connected to the stent of the stent-mounted valve. A crimping tool having a generally converging shape is adapted for use with the loading tool. Following connection of the loading tool to the stent-mounted valve, the loading tool operates to allow the stent-mounted valve to be drawn through the crimping tool, and loaded, in, a crimped state, into a delivery catheter. Also disclosed is a kit of the of the various components for effecting the delivery of the stent-mounted valve and a method for withdrawing, crimping, and loading a stent-mounted valve from a storage container into a delivery catheter for the performance of a transcatheter valve implantation procedure.Type: GrantFiled: June 15, 2016Date of Patent: January 29, 2019Assignee: Medtronic Ventor Technologies Ltd.Inventors: Yosi Tuval, Yuri Sudin, Ido Kilemnik, Igor Kovalsky, Raphael Benary, Guy Ezekiel

Patent number: 10004601Abstract: A prosthetic apparatus includes a main body having a lumen and configured for placement within a native annulus of a native valve complex. The main body is radially compressible to a radially compressed state for delivery into the heart and self-expandable from the compressed state to a radially expanded state. The apparatus also includes at least one arm coupled to and disposed outside of the main body. The arm being coupled to the main body such that when the main body is compressed to the compressed state, a leaflet-receiving space between the arm and an outer surface of the main body increases to receive a native valve leaflet therebetween, and when the main body expands to the expanded state in the absence of any radial inward forces on the main body or the arm, the space decreases to capture the leaflet between the outer surface of the main body and the arm.Type: GrantFiled: October 31, 2011Date of Patent: June 26, 2018Assignee: Medtronic Ventor Technologies Ltd.Inventors: Yosi Tuval, Ido Kilemnik, Raphael Benary

Patent number: 9918825Abstract: An endovascular stent-graft is provided that includes a structural member, which includes structural stent elements, at least a portion of which define a stent body when the stent-graft assumes a radially-expanded state; and a fluid flow guide. When the stent-graft assumes the radially-expanded state, (a) a first subset of the structural stent elements are configured to cause the stent body and the fluid flow guide to define a bulge that extends radially outward and has a greatest cross-sectional area that is equal to at least 120% of a cross-sectional area of a narrowest portion of the stent-graft rostral to the bulge, and (b) a second subset of the structural stent elements are not configured to cause the fluid flow guide to define the bulge. The structural stent elements of the first subset at least partially overlap the structural stent elements of the second subset lengthwise along the stent body.Type: GrantFiled: October 20, 2014Date of Patent: March 20, 2018Assignee: ENDOSPAN LTD.Inventors: Alon Shalev, Raphael Benary
