Abstract
A fabric medical device and method of making the device can include warp yarns and fill yarns woven together to form a first tubular extent having a first diameter, a second tubular extent having a second diameter, and a transition tubular extent having a graduated diameter between the first and second tubular extents. A tapered edge can be formed along the transition tubular extent by weaving such that a graduated number of warp yarns are disengaged along the transition tubular extent. A seam can be woven along the tapered edge that is configured to provide a substantially fluid-tight transition between the first and second tubular extents. The device can further include the warp yarns in at least the transition tubular extent having a tenacity higher than the tenacity of the fill yarns. The device can be a bone filler delivery device adapted to deliver bone filler in an internal body region.
