Patent number: 8740969Abstract: A fitting device (104) for fitting a stent-graft (100) into a lumen of a patient includes a catheter (110), a cannula (112) reciprocably carried in the catheter (110) and a pair of gripper claws (106) in the cannula (112). The gripper claws (106) grip onto a stent (102) at the proximal end (128) of the stent-graft (100) which a suture loop (108) is tied to a stent (102) at an intermediate position along the stent graft (100). The stent-graft (100) can be curved by pulling the end-most stent (102) backwards, that is by retracting the cannula (112) into the catheter (110) while the gripper claws (106) grip onto the stent (102). The proximal end of the stent-graft (100) can also be adjusted position-wise by moving the cannula (112) into and out of the catheter (110). Thus, precise positioning and curving of the stent-graft (100) can be achieved.Type: GrantFiled: February 13, 2009Date of Patent: June 3, 2014Assignee: Cook Medical Technologies LLCInventors: Kim Moegelvang Jensen, Bent Øhlenschlaeger

Publication number: 20110276119Abstract: 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: ApplicationFiled: October 9, 2009Publication date: November 10, 2011Applicants: Cook Incorporated, William Cook Europe APSInventors: Erik E.

Patent number: 8043356Abstract: A stent-graft (100) is provided with a tightenable loop element (104) having a first end terminated in a slip knot or self-tightening knot (112) and a second end which is received in and can slide in the knot (112). The knot (112) is tied by a suture to the stent-graft (100) so as to be fixed thereto. The loop (104) is fitted to the stent-graft (100) in a manner as to pass between the inside to the outside of the graft material and in such a manner that controlled curvature of the stent-graft (100) is possible, in particular control of the overlapping of adjacent stents held within the zone of the loop (104). An introducer assembly is also disclosed which includes a control cannula (120) able to the fixed to the stent-graft (100) during the deployment procedure, as well as a mechanism of suture loops (150, 152) at the proximal end of the stent-graft (100) for retaining this in a constricted form during the process of curving the latter during the deployment process.Type: GrantFiled: April 3, 2009Date of Patent: October 25, 2011Assignee: Cook Medical Technologies LLCInventors: Tilo Kölbel, Martin Malina, Kim Moegelvang Jensen, Bent Øhlenschlaeger, Erik E.

Publication number: 20110125249Abstract: 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: ApplicationFiled: November 15, 2010Publication date: May 26, 2011Applicants: MED Institute, Inc., William Cook Europe ApS, Cook IncorporatedInventors: Kim Moegelvang Jensen, Bent Oehlenschlaeger, Erik Rasmussen

Publication number: 20110040369Abstract: A stent graft (10) includes a tubular graft element (12) to which there are attached a plurality of stent rings (14). The stent rings (14) are formed of a plurality of stent struts (16) arranged in a zig-zag arrangement with alternating peaks (18) and valleys (20). The end-most stent (22) is located at the proximal end (24) of the graft tube (12). Between adjacent peaks (18) of the end-most stent (22), there is provided a series of bridging elements (28). These are preferably formed of Nitinol wire and to be substantially more flexible than the stent struts (14). The bridging elements (28) extend in the region of graft material between adjacent stent peaks (18) and are attached to the graft material, for example by suturing. The bridging elements (28) are substantially more flexible than the stent ring (22) and therefore impart little opening force on the graft material in comparison to the force produced by the stent ring (22).Type: ApplicationFiled: August 3, 2010Publication date: February 17, 2011Applicants: William Cook Europe ApS, Cook IncorporatedInventors: Erik Rasmussen, Bent Ohlenschlager, Kim Moegelvang Jensen, Jesper Schade Petersen

Publication number: 20100114291Abstract: 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: ApplicationFiled: October 30, 2009Publication date: May 6, 2010Applicants: William Cook Europe ApS, Cook IncorporatedInventors: Tilo Kölbel, Erik E.
