Publication number: 20230404589Abstract: Described are systems for delivering embolic coil devices, and components useful in such systems. The systems include a flexible elongate delivery shaft having a distal region and an embolic coil device detachably connected to the distal region of the elongate delivery shaft. In some forms, as detachably connected, at least some of the coil windings of the embolic coil device, such as those in a proximal segment of the coil windings, are in a resiliently longitudinally compressed condition. When the embolic coil device is detached from the delivery shaft, the coil windings resiliently move to a longitudinally extended condition, where the coil windings in the longitudinally extended condition are more open than they are in the resiliently longitudinally compressed condition. In some forms, the systems have a coil detachment interface at a distal region of a flexible elongate delivery shaft.Type: ApplicationFiled: June 21, 2023Publication date: December 21, 2023Applicant: Cook Medical Technologies LLCInventors: Jan Kristoffersen, Jens Kold, Louise Thrysøe Ekstrom, Kim Møgelvang Jensen, Betina Hansen, Benjamin Christian Waedeled, Anders Daniel Hviid Jakobsen

Patent number: 11376114Abstract: A stent graft for deployment in a curved lumen such as the aortic or thoracic arch comprises a constraining mechanism at its proximal end. A stent provided at the proximal end of the stent graft includes loops of material that co-operate with restraining wires that extend between a central guide wire carrier and a restraining wire cannula. The constraining mechanism acts to maintain the proximal stent constrained at both the proximal and distal ends of the proximal stent. The proximal stent is thus allowed to expand after expansion of the remainder of the stent graft during deployment. In an embodiment, the constraining mechanism acts to constrain two adjacent struts of the proximal stent at three points radially therearound, at the proximal end of the stent and at the distal end of the stent. The proximal stent may then overlap with the interior of an adjacent stent at an inner part of a curved vessel.Type: GrantFiled: June 8, 2020Date of Patent: July 5, 2022Assignee: Cook Medical Technologies LLCInventors: Tilo Kölbel, Erik E. Rasmussen, Bent Oehlenschlaeger, Kim Moegelvang Jensen

Patent number: 10195015Abstract: A stent graft includes a tubular graft element to which there are attached a plurality of stent rings. The stent rings are formed of a plurality of stent struts arranged in a zig-zag arrangement with alternating peaks and valleys. The end-most stent is located at the proximal end of the graft tube. Between adjacent peaks of the end most stent, there is provided a series of bridging elements. These are preferably formed of Nitinol wire and to be substantially more flexible than the stent struts. The bridging elements extend in the region of graft material between adjacent stent peaks and are attached to the graft material, for example by suturing. The bridging elements are substantially more flexible than the stent ring and therefore impart little opening force on the graft material in comparison to the force produced by the stent ring. However, the bridging elements impart enough force on the flaps of graft material between the peaks of the stent ring keep these flaps open, that is against the vessel wall.Type: GrantFiled: May 10, 2016Date of Patent: February 5, 2019Assignee: Cook Medical Technologies LLCInventors: Erik Rasmussen, Bent Oehlenschlaeger, Kim Moegelvang Jensen, Jesper Schade Petersen

Patent number: 10092295Abstract: A vascular occluder includes a tubular support element and a sleeve of occluding material disposed within the support element. The sleeve is twisted in the support creating a constriction which closes the lumen of the sleeve. The lumen of the sleeve can nevertheless be opened by a guide wire or cannula for over the wire delivery. Once the guide wire or cannula are withdrawn from the sleeve, the sleeve will close again by the action of blood pressure thereon. Blood pressure will act to maintain closing pressure on the sleeve, thereby avoiding or reducing the risk of recanalization.Type: GrantFiled: April 30, 2015Date of Patent: October 9, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Tue Thuren Bödewadt, Christina Rauff Hansen, Kim Møgelvang Jensen, Raimo Urban Jensen, Erik E.

Patent number: 9925032Abstract: A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.Type: GrantFiled: December 30, 2015Date of Patent: March 27, 2018Assignee: Cook Medical Technologies LLCInventors: Kim Moegelvang Jensen, Erik Edelboe Rasmussen, Bent Oehlenschlaeger

Patent number: 9855128Abstract: A stent graft (18) for deployment in a curved lumen such as the aortic or thoracic arch (130) comprises a constraining mechanism at its proximal end. A stent (4?) provided at the proximal end of the stent graft (18) includes loops of material (11) that co-operate with restraining wires (42) that extend between a central guide wire carrier (24) and a restraining wire cannula (8). The constraining mechanism acts to maintain the proximal stent (4?) constrained at three points around its circumference at both the proximal and distal ends of the proximal stent (4?). The proximal stent (4?) is thus allowed to expand after expansion of the remainder of the stent graft (18) during deployment. In an embodiment, the constraining mechanism acts to constrain two adjacent struts of the proximal stent (4?) at three points radially therearound, at the proximal end of the stent (4?) and at the distal end of the stent (4?).Type: GrantFiled: October 30, 2009Date of Patent: January 2, 2018Assignee: Cook Medical Technologies LLCInventors: Tilo Kölbel, Erik E.

Patent number: 9237960Abstract: An introducer assembly (100) including at its distal end a dilator tip (20) and an inner catheter for supporting an implantable medical device (1) for deployment, is provided with a plurality of strut elements (102, 202) extending from the dilator tip (20) to the proximal end of the medical device (1). The strut elements (102, 202) act to apply both a pulling and a pushing force against the proximal end of the medical device (1), having the effect of assisting in the correct positioning of the proximal end of the medical device in a patient's lumen, particularly where this is curved such as with the aortic arch. The strut elements (102, 202) form part of the introducer assembly and are removed from the patient following the deployment procedure. The device avoids the need for bare stents at the end of a stent graft.Type: GrantFiled: October 9, 2009Date of Patent: January 19, 2016Assignee: Cook Medical Technologies LLCInventors: Erik E.

Patent number: 9168160Abstract: A fenestrated implantable medical device, such as a stent graft (10) is provided with a plurality of zigzag stents (12) of which two or more form fenestrations (34, 36) using part of the stents (12) as a support frame (30, 32) for the fenestrations (34, 36). The frames (30, 32) are preferably covered by radiopaque wire (44) coiled around the stent structures. The radiopaque coil (44) provides easy reference to the fenestrations (30, 32) for imaging purposes.Type: GrantFiled: January 30, 2013Date of Patent: October 27, 2015Assignee: Cook Medical Technologies LLCInventors: Kim Moegelvang Jensen, Erik E.
