20090222077 | METHOD AND DEVICE FOR ATTACHING A STENT STRUCTURE TO AAA GRAFT MATERIAL - An aneurysmal repair system that utilizes a modified intraluminal scaffold apex and a delta stitch suture to secure graft material to the scaffold structure allows for no relative movement between the graft material and the scaffold structure. The absence of relative movement reduces the wear on the graft material. | 09-03-2009 |
20090264992 | COMBINATION BARB RESTRAINT AND STENT ATTACHMENT DEPLOYMENT MECHANISM - An aneurysmal repair system that utilizes a modified apex and delivery device is designed for accurate endoprosthesis delivery and deployment. The modified apex utilizes segments that overlap and hold one another down as well as the fixation barbs attached thereto. The delivery device holds or secures at least one section of the apex and may be easily released by retraction of a hold down member. | 10-22-2009 |
20090270967 | STENT ATTACHMENT AND DEPLOYMENT MECHANISM - A stent attachment and deployment mechanism is utilized to prevent the distal end of an endoprosthesis comprising fixation barbs or other fixation mechanism from deploying prior to the remaining sections of the fixation device. With this stent attachment and deployment mechanism accurate deployment may be achieved. | 10-29-2009 |
20100057187 | INTRAVASCULAR STENT HAVING IMRPROVED DESIGN FOR LOADING AND DEPLOYING - A stent may be inserted into a vessel in order to open and then maintain the patency of the vessel. The stent has a strut design that increases the overall fatigue resistance of the stent. Each strut is tapered to better distribute strain and thus increase fatigue resistance. In addition, some of the struts may comprise protrusions to increase the pushability of the stent during loading into a delivery device. | 03-04-2010 |
20100312330 | TWISTED ANCHORING BARB FOR STENT OF ABDOMINAL AORTIC ANEURYSM (AAA) DEVICE - A stent is provided for an endoprosthesis having a main body portion and two leg portions, particularly suitable for treatment of an abdominal aortic aneurism. The stent includes barbs that are twisted and shaped set to point radially outward. Each barb, as formed, points substantially perpendicular relative to the longitudinal axis of the stent, even when in a non-deployed configuration. The motion to move the barb into a deployed configuration for gripping tissue is a twisting motion which moves the barb from being substantially aligned with the circumference of the stent to extending radially outwards from the stent. | 12-09-2010 |

20120059452 | PERCUTANEOUS ENDOPROSTHESIS USING SUPRARENAL FIXATION AND BARBED ANCHORS - An endoprosthetic device for treating abdominal aortic aneurysms using suprarenal fixation. A stent ring is anchored in an area above the renal arties using self-flaring barbs that project during the nitinol expansion process. Sutures extend from the stent ring to an area below the renal arties to a bifurcated trunk portion comprising a nitinol fabric on a non-kinking frame. The bifurcated trunk is sealed proximal the iliac arteries and includes iliac leg holders having self-flaring retention struts for non-traumatic holding of iliac leg prosthetics. Suprarenal fixation and collapsible cells having retention projections and barbs that only flare during the nitinol expansion process assist in lowering the devices profile and sheathability for percutaneous delivery and may provide for recapturing the anchored device. | 03-08-2012 |
20120130412 | TOTAL OCCLUSION GUIDEWIRE DEVICE - A guidewire comprising a spreader or at least one centering device which may be used to open occluded vessels or other biological passages, especially chronic total occlusions. The guidewire may be used to either open the lumen or to center a boring device within the lumen, so that the chronic total occlusion can be crossed, and an interventional procedure can then be performed. | 05-24-2012 |
20130023978 | STENT GRAFT DEVICE - A stent graft device for implanting in a body lumen, comprising a stent with non-staggered or staggered apexes, said stent comprising a plurality of stent sections, bendable connecting members forming said non-staggered or staggered apexes and connecting each of said stent sections to other stent sections to form a zigzag pattern, wherein said stent is staggerdly sutured to a graft by a plurality of suture knots, and wherein said suture knots and staggered apexes are staggered when said stent sections are crimped, and methods of use thereof. | 01-24-2013 |
20130023979 | STENT GRAFT DEVICE - A stent graft device for implanting in a body lumen, comprising a stent with non-staggered or staggered apexes, said stent comprising a plurality of stent sections, bendable connecting members forming said non-staggered or staggered apexes and connecting each of said stent sections to other stent sections to form a zigzag pattern, wherein said stent is staggerdly sutured to a graft by a plurality of suture knots, and wherein said suture knots and staggered apexes are staggered when said stent sections are crimped, and methods of use thereof. | 01-24-2013 |
20130030517 | STENT GRAFT DEVICE - A stent graft device for implanting in a body lumen, comprising a stent with non-staggered or staggered apexes, said stent comprising a plurality of stent sections, bendable connecting members forming said non-staggered or staggered apexes and connecting each of said stent sections to other stent sections to form a zigzag pattern, wherein said stent is staggerdly sutured to a graft by a plurality of suture knots, and wherein said suture knots and staggered apexes are staggered when said stent sections are crimped, and methods of use thereof. | 01-31-2013 |
20130204281 | TOTAL OCCLUSION GUIDEWIRE DEVICE - A guidewire comprising a spreader or at least one centering device which may be used to open occluded vessels or other biological passages, especially chronic total occlusions. The guidewire may be used to either open the lumen or to center a boring device within the lumen, so that the chronic total occlusion can be crossed, and an interventional procedure can then be performed. | 08-08-2013 |
20130204291 | TOTAL OCCLUSION GUIDEWIRE DEVICE - A guidewire comprising a spreader or at least one centering device which may be used to open occluded vessels or other biological passages, especially chronic total occlusions.
