An assembly and a method are provided for manufacturing a joined assembly. A method for manufacturing includes fitting together and datuming a beam and a node, wherein at least one of the beam and the node is formed with an aperture, and wherein a cylindrical interface is formed between the beam and node. Further, the method includes advancing a mechanical fastener through the aperture to temporarily hold the beam and the node in an engagement. Also, the method includes injecting a structural adhesive into the cylindrical interface between the beam and the node. The method includes final joining the beam and the node by curing the structural adhesive.

A neurovascular catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a side wall defining a central lumen. The side wall includes a tubular inner liner, a tie layer separated from the central lumen by the inner liner, a helical coil at least partially overlapping the tie layer, and a tubular braid. A first section of adjacent windings of the helical coil can be spaced farther apart from each other than a second section of adjacent windings of the helical coil.

A preform charge is formed by forming an assemblage of preforms, wherein preforms in the assemblage are bonded to a neighboring preform such that the preform charge effectively becomes a single unit. The preform charge can then be added to a mold to fabricate a part via compression molding.

A neurovascular catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a side wall defining a central lumen. A distal zone of the tubular body includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, an outer jacket surrounding the helical coil, and an opening at the distal end. Adjacent windings of the helical coil are spaced progressively further apart in the distal direction. The opening at the distal end of the tubular body is enlargeable from a first inside diameter for transluminal navigation to a second, larger inside diameter to facilitate aspiration of thrombus into the lumen.
