Patent number: 11096811Abstract: A handle for an implant deployment device converts rotational movement into longitudinal movement in order to provide controlled release of one or more trigger wires. The handle also allows the trigger wire to be withdrawn into the device so that it does not need to be separately removed. A preferred handle includes a rotatable portion and a slidable portion. Releasable locks ensure that the handle is used to carry out implant deployment steps in a specific order.Type: GrantFiled: March 7, 2019Date of Patent: August 24, 2021Assignee: Cook Medical Technologies LLCInventor: Lars S. Nimgaard

Patent number: 9044266Abstract: An implant deployment device (10) includes a pusher member (30), inner catheter (24), dilator tip (20) upon which an implant (18) is supported during deployment into a lumen of a patient. A sheath (32) substantially surrounds the pusher member (30), the inner catheter (24), the dilator tip (20), covering the implant (18) and containing the implant (18) therewithin. The pusher member (30), inner catheter (24), dilator tip (20) has at least one longitudinal groove formed in its outer surface. This engages with at least one tooth (112) formed in an inner surface of the sheath (32) or an inner surface of a component of the device that is attached to the sheath (32), such as a clamping collar (90) or a locking unit (100). The tooth (112) engages with a longitudinal groove (80) and is able to move along the groove (80) in a longitudinal direction.Type: GrantFiled: September 19, 2008Date of Patent: June 2, 2015Assignee: Cook Medical Technologies LLCInventor: Lars S.

Patent number: 8603071Abstract: There is disclosed a locking unit (100) for locking a pusher (128) to a sheath assembly (164). The locking unit (100) includes a longitudinal locking portion (102) and a radial locking portion (104). The longitudinal locking portion (102) includes a plurality of cantilevered fingers (110) provided with longitudinally extending teeth (112) on internal surfaces thereof. A nut (108) can be tightened in order to bias the cantilevered arms (110) towards a pusher (128) such that the teeth (112) indent the outer surface of the pusher (128) to produce a strong and stable locking connection thereto. The radial locking section (104) latches onto the assembly integral with the sheath (164) so as to provide a radial locking action as well as a longitudinal locking action. The locking unit (100) provides a strong and reliable locking action between the pusher (128) and the sheath assembly (164) and can be easily removed by a clinician or surgeon during the deployment process.Type: GrantFiled: April 11, 2008Date of Patent: December 10, 2013Assignee: Cook Medical Technologies LLCInventors: Lars S. Nimgaard, Bent Ohlenschlaeger, Erik E. Rasmussen

Patent number: 8066756Abstract: A deployment device for deploying stents, stent-grafts and other implants into a patient includes a catheter (112) with a containment sheath (116). Held onto the catheter (112) is a stent-graft structure (120). The containment sheath (116) extends over the entirety of the stent graft section (122) so as to constrain it in its entirety on the catheter (112), until the sheath (116) is removed. The containment sheath (116) extends from the distal position (126) of the stent graft section (122) to the tip (114) and then into the central lumen (128) of the catheter (112). It may extend throughout the lumen (128) to the proximal end of the deployment device (10), in other words to the external manipulation section of the delivery device (10). The sheath (116) is withdrawn by pulling towards the external manipulation section of the delivery device. As this is effected, the containment sheath (116) is pulled over the end (114) of the catheter and into the central lumen (128) of the catheter (112).Type: GrantFiled: November 30, 2007Date of Patent: November 29, 2011Assignee: Cook Medical Technologies LLCInventors: Erik E.

Publication number: 20090105713Abstract: A deployment handle for an implant deployment device (100) facilitates withdrawal of a sheath (32). The sheath (32) is gripped between a first cam cleat (122) and a first ledge (124) and a second cam cleat (126) and a second ledge (128). The first cam cleat (122) and the first ledge (124) are attached to a carriage (120), which moves in a withdrawal direction upon actuation of a lever (130). During movement of the carriage (120) in the withdrawal direction, the first cam cleat (122) grips the sheath (32) or a sheath pulling member (118) thus causing movement of the sheath (32) in the withdrawal direction. During this movement, the second cam cleat (126) releases its grip upon the sheath (32) or a sheath pulling member (118). Upon release of the lever (130), the carriage (120) moves in a direction opposite to the withdrawal direction by means of a helical spring (140).Type: ApplicationFiled: October 9, 2008Publication date: April 23, 2009Applicants: William Cook, Europe ApS, Cook IncorporatedInventors: Lars S.
