  • 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).

  • Publication number: 20200069445
    Abstract: A stent-graft (20) comprises strut members (30) and a graft member (32), which is fixed to the strut members (30). The strut members (30) and the graft member (32) are arranged so as to define, when the stent-graft (20) is in a radially-expanded state: a main tube (40), which is shaped so as to define a main lumen (42); and a lateral tube (50), which (a) has (i) a distal end (52) and (ii) a proximal end (54) that is joined to a lateral wall (56) of the main tube (40) at a junction (60), (b) is shaped so as to define a lateral lumen (62) that is in fluid communication with the main lumen (42), and (c) defines a central longitudinal axis (64). The strut members (30) that define the lateral tube (50) are shaped so as to define two to four non-contiguous arcuate members (70), which (a) are centered around the central longitudinal axis (64); and (b) collectively subtend at least 150 degrees around the central longitudinal axis (64).

  • Patent number: 10540194
    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.

    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.

  • Patent number: 9918825
    Abstract: 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.

  • Patent number: 9770350
    Abstract: An endovascular stent-graft is provided that includes a flexible stent member, which includes a plurality of struts, which are shaped so as to define a generally circumferential section; a tubular fluid flow guide, which includes a graft material, and which is attached to the stent member; and at least one fixation member shaped so as to define a base at a first end thereof and a sharp tip at a second end thereof. The base is coupled to one of the struts that are shaped so as to define the generally circumferential section.
