Embodiment Construction

[0030] The description contained herein is an example of the invention and is not intended to limit the scope of the invention in any way. In general, the example devices described herein describe a therapeutic device that can be placed and adhered over the neck of an aneurysm to form a barrier between the blood vessel and the aneurysm. Then, at least one fast curing agent can be delivered into the aneurysm sac. Fast curing agents freeze blood in an aneurysm immediately.

[0031]An example device may include a mesh portion expandable from a collapsed configuration to an occluded configuration, wherein the mesh portion in the occluded configuration is shaped to occlude the neck of the aneurysm. Mesh portions may be adhered in place to occlude the neck of the aneurysm. In the blocking configuration, the mesh portion may generally have channel holes that work in conjunction with the reagent channels to deliver the fast curing agent through the channel holes and into the aneurys...

Abstract

The invention relates to an adhesive cover occluding device for aneurysm treatment. The invention provides a device which includes a net portion for occluding an aneurysm neck and an adhesive to secure the net portion. The device can further include a channel orifice opening in the net portion, and an agent channel for delivering a rapid-curing agent through the orifice into the aneurysm. Devicescan be delivered through a catheter to the aneurysm, and the net can expand to occlude the aneurysm neck, and the net can be adhered to the aneurysm neck. In devices including a channel orifice and agent channel, the rapid-curing agent can be injected into the aneurysm. During injection of the rapid-curing agent, the net portion can create a barrier to inhibit the rapid-curing agent from exiting the aneurysm. After injection of the coagulation agent, portions of the treatment device, excluding the net portion, can be extracted from the patient.

Description

technical field [0001] The present invention relates generally to medical devices, and more particularly to therapeutic devices for aneurysm treatment. Background technique [0002] Aneurysms can be complex and difficult to treat. For example, when an aneurysm is located near critical tissue, therapeutic access may be limited or unavailable. Such factors are of particular concern for intracranial aneurysms due to the brain tissue surrounding the intracranial vessel and the corresponding limited therapeutic access. [0003] Existing solutions include endovascular therapeutic access in which the internal volume of the aneurysm sac is removed or excluded from arterial blood pressure and flow. In this regard, aneurysm rupture is still possible because the inner walls of the aneurysm can continue to experience blood flow and associated pressure. [0004] Alternatives to endovascular or other surgical approaches may include occlusion devices. Such devices typically have incorp...
