Abstract: A single layer foldable reinforced bullnose hip and ridge cap shingle is cut from a single layer web of shingle material. The hip and ridge cap shingle includes an exposed portion, a tapered portion, and a portion in between that will be folded to form a bullnose edge. Two spaced apart perforated fold lines extend transversely across the shingle and two spaced apart transversely extending strips of reinforcing scrim material flank the perforated fold lines. To form a bullnose hip or ridge cap shingle, the shingle is folded first along one of the perforated fold lines and again along the other perforated fold line. This creates an exposed edge portion that is four layers thick and this extreme edge takes on a pleasant rounded bullnose appearance covered with granules. The reinforcing scrim is located at the edge and reinforces the bullnose edge to prevent cracking at the fold.

Abstract: The invention relates to a delivery catheter assembly (100) for a self-expanding stent or other device deployed in a similar manner, comprising: an inner shaft (1) located coaxially within an outer shaft (2). Each of the shafts (1, 2) comprises an elongate spiral-cut outer hypotube (12, 14). Each of the hypotubes (12, 14) has a plurality of slots (25) cut in the side wall thereof to increase the flexibility of the hypotube, and the slots are elongate slots (25) extending about the hypotube in a spiral or circumferential path which is interrupted at intervals by solid struts (20).
