摘要： A self-expanding braided stent includes at least a distal radial expansion ring added to a distal end of the stent body to increase a radial expansion force of the self-expanding braided stent in deployment of the stent, and to facilitate advancement of the stent through a delivery sheath by a core advancement wire. A proximal radial expansion ring is optionally added to a proximal end of the stent body to allow the stent to be recaptured following partial deployment by retraction of the core advancement wire, prior to full deployment of a proximal portion of the stent body.

摘要： A method for implanting a stent by providing an implantation system including a catheter, an expandable element, and a delivery wire, moving a first portion of the expandable element to exit the catheter, and maintaining a second portion of the expandable element within the catheter to establish a partially implanted configuration. Then moving the delivery wire independent of the expandable element in the partially implanted configuration, and enlarging a circumference of the expandable element in response to the moving the delivery wire.

摘要： A method of treating an aneurysm with an occlusion device having an inner embolic device with a proximal section and a distal section. The distal section has a first stiffness and the proximal section has a second stiffness. Further, the device has an expandable mesh capable of a collapsed position and an expanded position. The mesh can be disposed over, and attached to, a portion of the proximal section of the inner embolic device. The first stiffness is greater than the second stiffness and the inner embolic device comprises a preselected shape which assists in transforming the expandable mesh from the collapsed position to the expanded position.

摘要： A braid implant delivery and retraction device having a catheter, an expandable element and a delivery wire with distal, pusher, and recapture bumps. The expandable element having compressed, partially delivered, and implanted configurations. Delivering the braid can include engaging the distal bump till the braid is in the partially delivered configuration. If the user needs to recapture the braid, the recapture bump engages the braid proximally. To fully implant the braid, the distal bump is used until the braid is partially delivered and the distal bump disengages, now the pusher bump completes implanting by proximally pushing the braid completely out of the catheter.

摘要： A balloon assist device is disclosed which includes an inner body and a balloon bonded to the inner body. The inner body extends along an axis from a proximal end to a distal end and the cross-section of the inner body partially encloses the axis. The balloon assist device also includes an inflation tube in sealed communication with the volume enclosed by the inner body and the sheath. The balloon assist device may also include a pusher for sliding the balloon assist device along the catheter. The pusher may extend parallel to the axis from the proximal end of the balloon assist device in a proximal direction. The inflation tube may also be used as a pusher. The inner body of the balloon assist device may be a split cylinder extending along the axis from the proximal end to the distal end.

摘要： A braided stent system includes a stent body having a lumen formed by a plurality of braided members with interstices formed therebetween and a first expansion ring connected to the lumen of the stent body. The first expansion ring may include a frame defined by a plurality of interconnected support assemblies that are selectively positioned to impart an outwardly expanding radial force to the stent body, each support assembly can include a plurality of legs joined at a first intersection and connected to one of the other interconnected support assemblies at a second intersection opposite the first intersection. Each support assembly can include a claw portion mechanically connected to one or more of the interstices of the stent body so that the frame imparts an outward radial expansion force of the stent to facilitate use and delivery of the stent.

摘要： A vascular flow diverter includes a tubular mesh framework which includes a mesh cover and an opening. The tubular mesh framework is collapsible and configured to expand from a collapsed shape to a tubular shape when the vascular flow diverter is deployed. The mesh cover conforms to the shape of the tubular mesh, is surrounded by the tubular mesh framework, and is less porous than the tubular mesh framework. The opening is located within the mesh cover. A delivery wire passes through the opening in order to guide the flow diverter into place over an aneurysm.
