  • Patent number: 10952884
    Abstract: An endovascular stent-graft is provided that includes a flexible stent member and a tubular fluid flow guide. The tubular fluid flow guide includes first and second fabrics. The first fabric includes a first biologically-compatible substantially blood-impervious material, and is attached to and covers the stent member along a first longitudinal portion of the stent-graft. The second fabric includes a second biologically-compatible substantially blood-impervious material different from the first material, and is attached to and covers the stent member along a second longitudinal portion of the stent-graft. The second longitudinal portion is at least partially non-longitudinally-overlapping with the first longitudinal portion. Other embodiments are also described.

  • Publication number: 20210077247
    Abstract: A multi-component stent-graft system (10) comprises first, second, and third generally tubular stent-grafts (20, 22, 24), which are configured to assume radially-expanded states. The first stent-graft (20) is shaped so as to define a first lateral opening (34) when in its radially-expanded state. The second stent-graft (22) is shaped so as to define a second lateral opening (44) when in its radially-expanded state. The first and second stent-grafts (20, 22) are configured such that the second stent-graft (22) forms a blood-impervious seal with the first stent-graft (20) around the first lateral opening (34) when the second stent-graft (22) is disposed therethrough, and the first and the second stent-grafts (20, 22) are in their radially-expanded states.

  • Patent number: 10929161
    Abstract: A method, computer program product, and system includes a processor(s) obtaining, during runtime, from a compiler, two versions of a data parallel loop for an operation. The host computing system comprises includes a CPU and a GPU is accessible to the host. The processor(s) online profiles the two versions by asynchronously executing the first version, in a profile mode, with the GPU and executing the second version, in the profile mode, with the CPU. The processor(s) generates execution times for the first version and the second version. The processor(s) stores the executions times and performance data in a storage, where the performance data comprises a size of the data parallel loop for the operation. The processor(s) update a regression model(s) to predict performance numbers for a process of an unknown loop size. The processor(s) execute the operation with the CPU or the GPU based on the performance data.

  • Publication number: 20210041336
    Abstract: Methods and systems for evaluating fertility potential of a living sperm cell are presented and involve providing a predetermined classification function correlating between one or more physio spatial parameters of sperm cells and DNA fragmentation distribution in sperm cells, providing data indicative of the one or more physio spatial parameters of the living sperm cell, and applying the classification function to the one or more physio spatial parameters of the living sperm cell to thereby determine a DNA fragmentation level, inside the DNA fragmentation distribution, in the living sperm cell, the DNA fragmentation level being indicative of the fertility potential of the living sperm cell.

  • Patent number: 10905540
    Abstract: An endovascular prosthesis includes a stent-graft and an external coagulation inducer. The stent-graft includes a first portion of structural strut members and a first portion of a graft member, which, when the endovascular prosthesis is unconstrained in a radially-expanded state, together are shaped so as to define a blood-carrying tubular structure defining a lumen. The external coagulation inducer includes an extra-luminal skirt, which includes a second portion of the structural strut members and a second portion of the graft member, and is configured to assume: (i) when the endovascular prosthesis is removably disposed in a delivery sheath, a radially-compressed delivery state, in which the structural strut members of the first portion do not coincide with the structural stent members of the second portion, and (ii) when the endovascular prosthesis is unconstrained, a radially-expanded state, in which the extra-luminal skirt extends radially outward from an external surface of the stent-graft.

  • Publication number: 20200107925
    Abstract: An endovascular stent-graft (10, 110, 210, 310) is provided that includes elastic struts (20) and a fluid flow guide (30) that is fixed to first and second subsets (32, 34) of the struts (20). The struts (20) of the first subset (32) are arranged as circumferential cells (80) in circumferentially-continuous rings (56), which cause the fluid flow guide (30) to define substantially cylindrical tubular portions (40). The struts (20) of the second subset (34) cause the fluid flow guide (30) to define a bulge (42) having a greatest bulge radius from a central longitudinal axis (38) that is at least 5% greater than an average radius of the substantially cylindrical tubular portions (40) proximally and distally adjacent the bulge (42). The struts (20) of the second subset (34) define tip portions (50).
