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filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn.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： A system for mechanically deploying intraluminal implants is disclosed. The system is used with an implant that is delivered and/or deployed via a pull wire and includes a handle having a funnel and receiving channel for receiving the pull wire, a slider having a thumb grip and a wedge, and a shuttle having a grabber for grasping the pull wire. The thumb grip is pulled proximally to retract the wedge to cause the grabber to grasp the wire and retract the shuttle but not the wire. An extension spring linked between the slider and the shuttle abruptly pulls the shuttle to retract the pull wire after the slider is fully retracted.

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： A thromboembolic removal system for treating ischemic stroke, including a guide and occlusion catheter, an aspiration catheter, an aspiration pump, and a thromboembolic separator. During aspiration of thromboembolic material through the aspiration catheter, the separator element is advanced from and retracted into the catheter lumen to break up or prevent clogs or flow restrictions formed by the thromboembolic material. Longitudinal channels in the separator allow aspiration through the aspiration catheter to continue even when the separator is disposed in the aspiration catheter lumen.

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.
