Patent ID: 8813625

Claim:
A method of manufacturing a device for treating a vascular cavity, the method comprising: arranging a plurality of spools on a yarn wheel, each of the spools comprising wire; braiding the wire from each of the plurality of spools to form a textile structure, wherein braiding the wire comprises: braiding the wire for a first duration to form a first segment of the textile structure, wherein the first duration comprises: a third duration, and a fourth duration after the third duration, wherein braiding the wire during the first duration comprises: rotating the yarn wheel 180° at a first speed during the third duration, rotating the yarn wheel 180° at a second speed different than the first speed during the fourth duration, and pulling a puller at a third speed, at least one of the first speed and the second speed being greater than the third speed, and braiding the wire for a second duration to form a second segment of the textile structure, wherein the second duration comprises: a fifth duration, and a sixth duration after the fifth duration, wherein braiding the wire during the second duration comprises: rotating the yarn wheel 180° at a fourth speed during the fifth duration, rotating the yarn wheel 180° at a fifth speed different than the fourth speed during the sixth duration, and pulling the puller at a sixth speed, at least one of the fourth speed and the fifth speed less than the sixth speed; and heat treating the textile structure, wherein after the heat treatment the textile structure is expandable from a compressed state to an expanded state, the textile structure comprising a bulb in the expanded state.
