摘要: Embolic coils are disclosed. The coils include an inner coil, an outer coil, and a stretch resistant member. Some embodiments include a large diameter outer coil formed from a small diameter wire. The inner coils may be either closed pitch or open pitch. Alternative coils include an inner coil that is shape set to a diameter that is larger than the diameter of the outer coil. Another alternative coil has multiple stretch resistant members.

摘要: A delivery catheter for accessing the intra-cranial vascular includes a rigid proximal section and a distal section having an outer diameter and flexibility suitable for advancement into the intra-cranial vasculature, such as the Petrous segment or the Cavernous segment of the internal carotid artery. The wall thickness and rigidity of the catheter decrease from the proximal section to the distal section, preferably in discrete segments each having reduced wall thickness and/or durometer relative to proximally adjacent sections. An intra-cranial access system includes the delivery catheter and a selection catheter insertable through the lumen of the delivery catheter. The selection catheter is shaped to facilitate selection of the target branch of the neurovasculature off the aortic arch and allows the delivery catheter to be advanced over the selection catheter into the selected branch.

摘要: Embolic coil implant systems and methods whereby coils are mechanically detachable are disclosed. The coils include a retention element that may be releasably retained within the distal end of an implant tool. The implant tool may include a fulcrum configured to engage a first filament and prevent the release of the coil when the first filament is engaged. Alternatively, an urging means and aperture may be disposed within the sidewall of the implant tool, and a first filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn. The implant tool may also include an alignment member for aligning the first filament.

摘要: An aneurysm occlusion device is positionable within a cerebral blood vessel covering a neck of an aneurysm on the blood vessel. The device includes a tubular element having a lumen surrounded by an occlusive sidewall including a plurality of gaps. The gaps are sufficiently small to cause at least partial occlusion against flow of blood from the blood vessel through the side wall into the aneurysm, but are expandable in response to a fluid pressure differential between a first area inside the lumen and a second area outside the lumen to allow flow of fluid through the side wall between the blood vessel and a side branch vessel.

摘要: A stent may comprise a plurality of serpentine bands and connectors. A first connector may overlap a second connector when the stent is unexpanded. The first connector may also overlap the second connector in an unexpanded state when the stent is subject to compressive forces in the local area of the connectors, such as when the connectors are located on the inside of a curve. The second connector may be shaped according to a rotation of the first connector about the centroid of the cell between the first connector and the second connector.

摘要: An endoprosthesis for deployment within a body passage includes a framework and a metallic film, which can circumferentially surround the framework or be surrounded by the framework. The framework and metallic film can be attached without using a third material, e.g., without sewing. The framework can define a circumferential recess along at least a portion of its length and circumference. The recess accommodates at least a portion of the metallic film therein.
