Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

A catheter system utilizing one or more sensors is described. The catheter can be used as part of an embolic coil system, guidewire system, or combined embolic coil/guidewire system where the devices interact with the catheter system. A variable detachment embolic coil system and guidewire system are also described.

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filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn.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.

A device for endovascular treatment to ameliorate aneurysm recurrences by deploying a treatment mesh having a plurality of vertically oriented elongated support reinforcement elements that are substantially parallel and oriented upon a plane in communication with the mesh. Upon deployment, the array of distal ends of the support extensions and reinforcements are substantially oriented upon a plane, which plane is in substantially the same orientation as the opening of the aneurysm into which the device was deployed. The treatment mesh may incorporate a coating of hydrogel, optionally impregnated with pharmaceutical compounds.

Embolic coils with detachable segments that are separated by detachment capsules that are thermolytically degradable such that varying lengths of coil may be implanted into a vascular malformation to occlude same. The capsules are radiotransparent when compared to the adjoining coil segments to the location of the segments is easily seen. The capsules further include protruding electrical contacts that make positive contact with terminals on a delivery catheter. The terminals on the delivery catheter serve as markers so the relationship between the detachment capsules and the terminals is easily visible under x-ray.

A vasculature occlusion device detachment system including a wound coil heating element of a predetermined resistivity. A coil securing suture terminates in a proximal bead retained within the wound coil heating element while the distal end of the coil securing suture extends beyond the distal end of the wound coil heating element and is attached to the proximal end of the vasculature occlusion device. The coil securing suture is independently rotatable of the wound coil heating element 360 degrees about a longitudinal axis extending therethrough the wound coil heating element. A power source applies electrical current to the wound coil heating element via an electrically conductive corewire and separate insulated electrically conductive wire to increase its resistance and, as a result of the heat produced, sever the coil securing suture.

A vaso-occlusive device delivery assembly includes a pusher assembly having proximal and distal ends, a conductive sacrificial link disposed at the distal end of the pusher assembly, and a vaso-occlusive device secured to the pusher assembly by the sacrificial link. The pusher assembly includes first and second conductors extending between the proximal and distal ends thereof. The sacrificial link is electrically coupled between the first and second conductors, such that the first conductor, sacrificial link and second conductor form an electrical circuit, and, when a disintegration current is applied through the sacrificial link through the first and second conductors, the sacrificial link thermally disintegrates, thereby releasing the attachment member and vaso-occlusive device from the pusher assembly.

This invention is a bowl-of-spaghetti type intrasacular aneurysm occlusion device including: a catheter; embolic coils; a bowl or cup shaped neck bridge; an opening in the neck bridge through which the coils are inserted into the aneurysm sac; and a closure mechanism which closes the opening after the coils have been inserted into the aneurysm sac. It is a called a bowl-of-spaghetti type device because the neck bridge can look like a bowl and the embolic coils can look like spaghetti noodles in the bowl.
