Abstract
Disclosed herein is a 3-D unibody woven article comprising: a) a tubular member having a lumen; b) a cushioning member wherein a portion of the cushioning member comprises a central cavity housing a portion of the lumen; and c) a woven seal positioned at a distal end of the cushioning member.
Claims23
A woven article defined by a proximal end and a distal end, wherein the woven article is a 3-D unibody article and comprises:
- (a) a tubular member having a lumen disposed between a first open end of the tubular member and a second end of the tubular member;
- wherein the tubular member has a first thickness,
- wherein the first open end defines the proximal end of the woven article;
- wherein the lumen has a diameter d1 and a length l1;
- (b) a cushioning member having a second thickness,
- wherein an outer surface of the tubular member seamlessly transitions into an outer surface of the cushioning member at a length l2 from the first open end of the tubular member, thereby forming a proximal end of the cushioning member, wherein l2 is less than l1,
- wherein a portion of the cushioning member comprises a central cavity housing a portion of the lumen having a length l3, such that the second end of the tubular member is positioned within the central cavity of the cushioning member;
- and
- (c) a woven seal positioned at a distal end of the cushioning member.
An implantable medical device comprising a self-expanding frame having an upper region, an intermediate region, and a lower region, wherein the frame is configured to radially expand and contract for deployment within a body cavity and wherein the self-expanding frame comprises one or more anchors disposed along the lower region;
- wherein each of the one or more anchors is configured to anchor the implantable medical device to a portion of a patient's natural anatomy, and wherein at least a portion of the one or more anchors is positioned within a woven article;
- wherein the woven article comprises:
- a tubular member having a lumen disposed between a first open end of the tubular member and a second end of the tubular member;
- wherein the tubular member has a first thickness,
- wherein the first open end defines a proximal end of the woven article;
- wherein the lumen has a diameter d1 and a length l1;
- a cushioning member having a second thickness,
- wherein an outer surface of the tubular member seamlessly transitions into an outer surface of the cushioning member at a length l2 from the first open end of the tubular member, thereby forming a proximal end of the cushioning member, wherein l2 is less than l1,
- wherein a portion of the cushioning member comprises a central cavity housing a portion of the lumen having a length l3, such that the second end of the tubular member is positioned within the central cavity of the cushioning member;
- and
- a woven seal positioned at a distal end of the cushioning member.
