Publication number: 20100280586Abstract: Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device includes a support frame having struts and a weakened frame portion, and a remodelable material tensionably attached to the support frame. The weakened frame portion has a first configuration in which the support frame has a first outward radial force and a second configuration in which the support frame has a second, lesser outward radial force. The remodellable material restricts expansion of the frame from a radially compressed configuration to a radially expanded configuration when the weakened frame portion is in the first configuration. The remodelable material can form one or more valve leaflets adapted to regulate fluid flow in a body vessel, such as a vein.Type: ApplicationFiled: May 11, 2010Publication date: November 4, 2010Applicant: COOK INCORPORATEDInventors: Brian C.

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

Publication number: 20100274277Abstract: An embolic protection device for capturing emboli during treatment of a lesion in a blood vessel is presented. This embolic protection device generally comprises a plurality of struts having a predetermined shape and being configured to move between an expanded state for engagement with the blood vessel and a collapsed state for filter retrieval and delivery and a filter portion circumferentially attached to the struts having a proximal end and a distal end; the filter portion extending freely from the proximal end to a closed distal end. The filter portion forms at least one annulus chamber in the expanded state with the closed distal end of each chamber being not coincident to the center longitudinal axis of the blood vessel in order capture emboli in the chambers and to reduce any overall restriction of blood flow through the filter portion.Type: ApplicationFiled: April 27, 2009Publication date: October 28, 2010Applicant: Cook IncorporatedInventor: Elizabeth A. Eaton

Publication number: 20100274340Abstract: A stent graft deployment device (10) has a tubular fixed handle (34, 36) to be gripped and held by a user and an elongate release handle (30) extending through the fixed handle so that the release handle can be moved through the fixed handle. The deployment device assembly has a pusher (38) and a sheath (18) to cover a stent graft (64) on the pusher. The pusher is connected to the fixed handle and the sheath is connected to the release handle so that retraction of the release handle through the fixed handle causes the sheath to be retracted from the stent graft on the pusher. The fixed handle includes a grip component (34) that grips the pusher and a rotator component (36) that grips a release clamp (48) on the pusher. The release clamp has trigger wires for the release of the stent graft attached to it.Type: ApplicationFiled: August 13, 2008Publication date: October 28, 2010Applicants: William Cook Austrialia Pty Ltd, Cook IncorporatedInventors: David Ernest Hartley, Werner Dieter Ducke
