Publication number: 20090270903Abstract: A vascular occlusion device deployment system for placing an occlusion device at a preselected site within the vasculature of a patient. The deployment system employing a pusher having a lumen with an opening at the distal end of the pusher. A vascular occlusion device is connected to the distal end of the pusher by a portion that is removeably disposed within the opening. The portion of the occlusion device is forced out of the opening by an expandable reaction chamber, thereby deploying the occlusion device. The expandable reaction chamber, prior to deployment, has multiple chambers separated by a heat-dissolvable membrane. When the membrane is dissolved, components from the chambers react and expand, leading to deployment.Type: ApplicationFiled: June 30, 2009Publication date: October 29, 2009Applicant: Cordis Development CorporationInventors: Marc W. Litzenberg, Donald K. Jones, Vladimir Mitelberg

Patent number: 7582101Abstract: The disclosure describes apparatuses and methods for the luminal delivery of therapeutic devices. The apparatus includes a decoupling assembly comprising a retention element, a energy-responsive element and a thermally sensitive element. The application of heat to the thermally sensitive element alters its configuration such that it no longer maintains the retention element in engagement with the therapeutic device, releasing the therapeutic device.Type: GrantFiled: February 28, 2006Date of Patent: September 1, 2009Assignee: Cordis Development CorporationInventors: Donald K.

Publication number: 20080195136Abstract: Thin film devices implantable within a human subject for occlusion of an aneurysm or body vessel are provided. The devices are movable from an elongated, collapsed configuration for delivery to a deployed configuration within the body. Open slots in selected portions of the device telescope as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while also decreasing in porosity for preventing blood flow. Closed slits in other portions of the device open as the device moves to its deployed configuration, which causes the associated portions to longitudinally foreshorten and radially expand, while remaining open for fluid flow or endothelialization. The occlusion devices may be either self-supporting or supported by a strut structure. Additionally, the occlusion devices may comprise a plurality of mesh layers having unaligned pore systems which further reduce porosity in desired portions of the deployed configuration.Type: ApplicationFiled: September 16, 2005Publication date: August 14, 2008Applicant: CORDIS DEVELOPMENT CORPORATIONInventors: Frederick Feller, Donald K. Jones, Darren R. Sherman

Patent number: 7344558Abstract: A vascular occlusion device deployment system for deploying an occlusion device at a preselected site within the vasculature of a patient. The deployment system includes a pusher which has a constrictor located at the distal end portion of the pusher. The constrictor has a channel which receives a portion of the occlusion device. The constrictor has a proximal end portion and a distal end portion wherein the proximal end portion can be moved relative to the distal end portion to reduce the size of the channel. When the channel size is reduced, the constrictor grasps the portion of the occlusion device located within the channel. When it is desired to deploy the coil, the constrictor is moved in the opposite direction to increase the size of the channel and release the coil's grasp of the occlusion device.Type: GrantFiled: February 28, 2006Date of Patent: March 18, 2008Assignee: Cordis Development CorporationInventors: Juan A.
