FABRIC MEDICAL DEVICE HAVING A TAPERED TRANSITION AND METHOD OF MAKING
First Claim
1. A device, comprising:
- a plurality of warp yarns and fill yarns woven together;
a first tubular extent having a first diameter and a formed shape;
a second tubular extent having a second, different diameter and a formed shape;
a transition tubular extent having a graduated diameter between the first and second tubular extents;
a tapered edge along the transition tubular extent formed by a weaving pattern in which a graduated number of warp yarns are disengaged along the transition tubular extent;
a seam woven along the tapered edge and configured to provide a substantially fluid-tight transition between the first tubular extent and the second tubular extent; and
the warp yarns in at least the transition tubular extent having a tenacity higher than a tenacity of the fill yarns.

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.

15. A method for making a device, comprising:
-
selecting a warp yarn and a fill yarn each having a tenacity, the tenacity of the warp yarn being higher than the tenacity of the fill yarn; weaving together a plurality of the warp yarns and fill yarns to form the device having a first tubular extent having a first diameter, a second tubular extent having a second, different diameter, and a transition tubular extent having a graduated diameter between the first and second tubular extents; disengaging a graduated number of warp yarns along the transition tubular extent to form a tapered edge; weaving a seam along the tapered edge so as to provide a substantially fluid-tight transition between the first tubular extent and the second tubular extent. - View Dependent Claims (16, 17, 18, 19, 20, 21)
