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: 9724220Abstract: An introducer for deploying an implantable medical device such as a stent (60), stent graft (80) or other similar device is provided with an outer sheath (132,232) which is provided with a series of internally longitudinally extending channels (136. 236) and interdigitating protrusions (134, 234) extending therein. At least on stent ring (0) of the medical device is provided with one or more barbs (104) which point radially outwardly of the device, including when this is compressed onto the introducer. The barbs (104) lie within the channels (136, 236) which the remainder of the medical device is retained in its compressed form by the elongate protrusions (134, 234). The channels (136, 236) allow for the provision of relatively stiff barbs (104). The barbs (104) can be better suited to ensuring the correct placement of the medical device than flexible barb arrangements.Type: GrantFiled: April 7, 2010Date of Patent: August 8, 2017Assignee: Cook Medical Technologies LLCInventor: Erik Edelboe Rasmussen

Patent number: 8114145Abstract: A prosthesis deployment device having a elongate catheter body and a trigger wire guide concentric about the elongate catheter body where the trigger wire guide comprises three trigger wire lumens separate and apart from a guide wire lumen, with three trigger wires being at least partially disposed in the three trigger wire lumens and configured to engage a portion of a prosthesis to retain the prosthesis adjacent to the trigger wire guide.Type: GrantFiled: March 11, 2010Date of Patent: February 14, 2012Assignee: Cook Medical Technologies LLCInventors: David Ernest Hartley, Edward Graham Mills, Erik Edelboe Rasmussen, Jens Vejby Schultz

Publication number: 20100274341Abstract: An introducer assembly (10) includes a guide wire catheter (12), a pusher element (16), an external manipulation unit (28) and an external sheath (30). The distal end (18) of the pusher element (16) is bonded, with adhesive or other bonding agent (32), to the guide wire catheter (12) so as to fix these components together at the distal end (18) of the pusher element (16). This reduces twisting of the pusher element (16) relative to the guide wire catheter (12) and thus twisting of any implantable medical device carried on the introducer assembly (10). This can reduce incorrect deployment of the implantable medical device and reduce instances of an abortive medical procedure. In addition, such bonding increases the torque resistance of the guide wire catheter (12) and pusher element (16) to reduce overall twisting at the distal end of the introducer assembly (10).Type: ApplicationFiled: April 28, 2010Publication date: October 28, 2010Applicants: William Cook Europe ApS, Cook IncorporatedInventors: Erik Edelboe Rasmussen, Bent Oehlenschlaeger, Jesper Schade Petersen

Patent number: 7803177Abstract: A trigger wire guide for a prosthesis deployment device. The prosthesis deployment device has a proximal end extending to a proximal nose cone dilator and having a trigger wire or wires and trigger wire release mechanism to retain the proximal end of a prosthesis adjacent the nose cone dilator. The trigger wire guide retains the trigger wire or wires to prevent fouling of the trigger wire with a prosthesis when the prosthesis is carried on the deployment device. The guide can be crimped or soldered to a guide wire catheter or concentric with it.Type: GrantFiled: May 29, 2003Date of Patent: September 28, 2010Assignees: Cook Incorporated, William A.

Patent number: 7611529Abstract: A stent graft deployment apparatus (10) which has a deployment catheter (11) with a proximal end (5) to be introduced into a patient and a distal end (3) to remain outside a patient and at a proximal end thereof a region to contain a stent graft (21). A sheath (25) extends over and covers the stent graft and can be moved to expose the stent graft to enable deployment of the stent graft. A nose cone dilator (17) is positioned at the proximal end of the deployment catheter and can be curved. A capsule (40) provides a distal retention arrangement for the stent graft.Type: GrantFiled: June 30, 2003Date of Patent: November 3, 2009Assignees: Cook Incorporated, William Cook Europe ApS, William A.

Patent number: 5725534Abstract: An assembly for positioning an embolization coil (4) in the vascular system. The assembly includes a guidewire having a relatively flexible distal section (6), which has a central core (7) and a threading coil (10), the distal turns (11) of which are arranged with such mutual spacing (12) that the embolization coil can be threaded in and out of the threading coil. The distal end section of the guidewire is manufactured with an elongated, rotationally symmetrical member, such as cylindrical member (13), and the peripheral surface of the member is provided with a bonding layer (25). Then the distal turns of the threading coil are positioned in the desired helical shape on the external side of the member, and the bonding layer is activated so that the distal turns are fixed to the member in this shape.Type: GrantFiled: June 7, 1995Date of Patent: March 10, 1998Assignee: William Cook Europe A/SInventor: Erik Edelboe Rasmussen
