Abstract: An endovascular self-expanding stent system that can include a braid with a proximal end, a distal end, and a lumen formed therebetween. The braid can be formed from one or more wires woven to comprise interstices. A first expansion ring can be connected to the proximal end of the braid. A second expansion ring can be connected to the distal end of the braid. Each expansion ring can include a frame that imparts an outwardly expanding radial force to the braid. The frame can include a plurality of elongate members interconnected by one or more intersections.

Abstract: Stents generally can include multiple longitudinal elements each extending over a majority of the length of the stent and each having alternating flexible and rigid segments. The stents can include nodes positioned between the flexible and rigid segments on the longitudinal elements and interconnecting members extending circumferentially to connect adjacent longitudinal elements at the nodes. The longitudinal elements can have a wave pattern and the interconnecting members can have a branch structure connecting peaks from one longitudinal element to troughs of an adjacent longitudinal element. The resulting stent structure can have lateral and longitudinal flexibility needed to navigate and conform to intracranial arteries with the benefits of recapturability and structural integrity of a closed cell design.

Abstract: A stretch-resistant occlusive device, and method of manufacturing such a device, having a helically wound coil defining a coil lumen extending along the entire axial length of the coil from a proximal end portion to a distal end portion. The device further includes a headpiece having a proximal end, a distal end attached to the proximal end portion of the coil, and a headpiece lumen extending between the proximal and distal ends of the headpiece. An anchor filament extends through the headpiece lumen, has at least one proximal end secured to the proximal end of the headpiece, and has a distal portion defining an eye positioned distal to the distal end of the headpiece. A stretch resistant member is positioned within the coil lumen, has a proximal portion extending through the eye, and has at least one distal end secured to the distal end of the coil.

Abstract: A system for delivering and releasing a self-expanding stent includes a catheter, a tubular self-expanding stent configured to be constrained from expanding when the tubular self-expanding stent is contained within the catheter, and a core advancement wire disposed within and extending through a lumen of the tubular self-expanding stent. One or more stop members on the core advancement wire engage one or more anchor members on the stent when the core advancement wire is translated longitudinally toward the one or more anchor members.

Abstract: An occlusive device suitable for endovascular treatment of an aneurysm in a region of a parent vessel in a patient, including a structure having a fixed porosity and having dimensions suitable for insertion into vasculature of the patient to reach the region of the aneurysm in the parent vessel. The device further includes a frangible material supported by the structure which initially provides a substantial barrier to flow through the frangible material and is capable of at least one of localized rupturing and localized eroding, in the presence of a pressure differential arising at an ostium of a perforator vessel communicating with the parent vessel, within an acute time period to minimize ischemia downstream of the perforator vessel.

Abstract: A stretch-resistant occlusive device having an elongated, substantially cylindrical porous elastomeric structure and at least one of an elongated stretch-resistant tube and at least one stretch-resistant filament. The porous structure lies within an elongated outer embolic structure such as a helically wound embolic coil.
