Publication number: 20180140305Abstract: This invention is an intrasacular aneurysm occlusion device with a proximal resilient stent which becomes wider than the aneurysm neck and a distal flexible net which is expanded by being filled with embolic members. The stent and the net work together. The stent occludes the aneurysm neck and prevents the device from slipping out. The net conforms to the walls of even an irregularly-shaped aneurysm sac and keeps the stent pressed against the inside of the aneurysm neck. This has advantages over the prior art, especially for aneurysms with irregularly-shaped sacs.Type: ApplicationFiled: January 9, 2018Publication date: May 24, 2018Applicant: Aneuclose LLCInventor: Robert A. Connor

Patent number: 9907684Abstract: This invention gives physicians in situ control to create differences in wall porosity between different areas of a stent wall. This enables a physician to customize the stent within a blood vessel to selectively block blood flow to an aneurysm with a low-porosity area of the stent wall, but allow blood flow to nearby branching vessels through one or more high-porosity areas of the stent wall. The method comprises inserting a stent into a blood vessel and, in situ, expanding the stent in a non-uniform manner, thereby causing one or more areas of the stent wall to have a lower post-expansion porosity than the rest of the stent wall. With this invention, physicians can selectively block blood flow into an aneurysm while maintaining blood flow into nearby branching vessels, even in tortuous and complex vessel configurations.Type: GrantFiled: May 8, 2013Date of Patent: March 6, 2018Assignee: Aneuclose LLCInventors: Robert A. Connor, Tariq M. Janjua

Publication number: 20160206321Abstract: This invention is an aneurysm occlusion device with a sequence of shape-changing embolic members which travel through a lumen into an aneurysm sac. The longest axes of these members are substantially parallel to the lumen as within the lumen and longest axes of these members are substantially parallel to the circumference of the neck of the aneurysm after the member exit the lumen. This device can fill a greater percentage of an aneurysm sac, better reduce blood circulation into the aneurysm sac, and better conform to an irregularly-shaped aneurysm sac than coils or single hollow mesh structures.Type: ApplicationFiled: March 27, 2016Publication date: July 21, 2016Applicant: Aneuclose LLCInventor: Robert A.

Patent number: 8974487Abstract: A device to treat an aneurysm can include a plurality of soft and compressible fill members. A flow conduit can carry the fill members in a liquid flow. A flexible, expandable, and liquid-permeable net or mesh enclosure can be inserted into and to fit within the aneurysm. The net or mesh enclosure can receive and retain the plurality of fill members while openings in the net or mesh enclosure allow enough liquid flow through the net or mesh enclosure to transport the fill members into the net or mesh enclosure. A resulting accumulation of the plurality of fill members within the net or mesh enclosure causes the net or mesh enclosure to expand and to come into contact with and generally conform with an interior wall of the aneurysm. This can substantially occlude the aneurysm and retain the net or mesh enclosure within the aneurysm.Type: GrantFiled: April 24, 2009Date of Patent: March 10, 2015Assignee: Aneuclose LLCInventors: Robert A.
