Abstract: Devices for loading intravascular treatment devices into a sheath and associated systems and methods are disclosed herein. A sheathing tool may include, for example, a first channel extending to a first opening, the first channel configured to receive a treatment device in a constrained state therethrough. The treatment device may include an elongated member and a first element and a second element at a distal region of the elongated member. The second channel may extend to a second opening, the second opening surrounded by a sidewall and configured to receive the treatment device in the constrained state therethrough, wherein the second opening is spaced apart from the first opening by a gap, and wherein a length of the gap is great enough to allow the first element to self-expand over the sidewall while the second element generally maintains its diameter in the constrained state while crossing the gap.

Abstract: A stent-graft prosthesis includes a generally tubular outer PTFE layer, a generally tubular helical stent, a generally tubular inner PTFE layer, and a suture or fabric support strip. The outer PTFE layer defines an outer layer lumen. The helical stent is disposed within the outer layer lumen and defines a stent lumen. The inner PTFE layer is disposed within the stent lumen and defines an inner layer lumen. The suture includes a suture first end coupled to a stent first end and a suture second end coupled to a stent second end, with the suture disposed between the outer PTFE layer and the inner PTFE layer. Alternatively, the fabric support strip is disposed between the outer and inner PTFE layers. The suture or fabric support strip may include a plurality of sutures or fabric support strips and may be spaced equally around a circumference of the inner PTFE layer.
