Abstract: A PCB analysis utilizes manufacturing capability data shared in a multi-tenant collaborative network in a mixed cloud and on-premise environment. Access to a tenant's account of a DFM application deployed on the tenant's premises is provided. The DFM application is enabled to activate the PCB analysis on a DFM profile with manufacturing capability data. The tenant's account requests a utilization authorization of a given DFM profile stored in a cloud data layer. When the utilization is authorized, the given DFM profile is downloaded embedded in a locked DFM envelope, which locks together the given DFM profile with an injected identifier of the authorized tenant's account. Via the DFM application, when logged into the tenant's account, the PCB analysis is activated by permitting the unlocking of the DFM profile from the DFM envelope only when the identifier of the tenant's account is the same as the injected identifier.

Abstract: An endovascular system includes an elongate delivery shaft assembly, which, when a stent-graft is removably constrained in a radially-compressed delivery state along a distal end portion of the delivery shaft assembly, is shaped so as to define a self-orienting portion, which is shaped so as to define (a) at least proximal and distal curved portions, the proximal curved portion disposed more proximal than the distal curved portion, and (b) at least one point of inflection on a central longitudinal axis of the delivery shaft assembly longitudinally between the proximal and the distal curved portions. Upon positioning of a distal tip of the system near a bifurcation of a brachiocephalic artery from an aortic arch, the self-orienting portion automatically rotationally orients itself in the aortic arch to a rotational orientation in which an inferior lateral opening of the stent-graft faces upstream in the aortic arch. Other embodiments are also described.

Abstract: A method for treating a subject includes providing an endovascular system that includes a stent-graft and an elongate delivery shaft assembly. When the delivery shaft assembly is unconstrained and the stent-graft is removably constrained along a distal end portion of the delivery shaft assembly, the delivery shaft assembly is shaped so as to define a self-orienting portion, which is shaped so as to define at least proximal and distal curved portions. The delivery shaft assembly is transvascularly introduced into a descending aorta of the subject and a distal end of the delivery shaft assembly is advanced to an aortic arch, such that the self-orienting portion assumes a desired rotational orientation in the aortic arch. While the distal end of the delivery shaft assembly is positioned in the aortic arch, the stent-graft is released from the distal end portion of the delivery shaft assembly. Other embodiments are also described.

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.

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).
