Patent number: 11590011Abstract: What is disclosed are medical devices comprising a rounded, thin-walled, expandable metal structure (“ballstent”) and a flexible, elongated delivery device (“delivery catheter”) and systems and methods of use for treating saccular vascular aneurysms with the medical devices. Ballstents comprised of gold, platinum, or silver that can be compressed, positioned in the lumen of an aneurysm, and expanded to conform to the shape of the aneurysm are disclosed. The external surface of ballstents can be configured to promote local thrombosis and to promote the growth of tissue into and around the wall of the ballstent in order to seal the aneurysm and fix the ballstent in place in the aneurysm. The wall of the ballstent can also be configured to release drugs or pharmacologically active molecules, such as those that promote thrombosis, cell proliferation, extracellular matrix deposition, and tissue growth.Type: GrantFiled: January 21, 2020Date of Patent: February 28, 2023Assignee: Metactive Medical, Inc.Inventors: F. Nicholas Franano, Katherine J. Stephenson

Publication number: 20220031486Abstract: A medical device comprising a compressed, inflatable, detachable balloon attached to a catheter and methods of use for occluding blood vessels or treating vascular aneurysms are disclosed. The balloon may be configured such that it can be detached from the catheter by mechanical means. The surface of the balloon may be configured to promote the growth of tissue into the wall of the balloon and to release drugs or pharmacologically active molecules, so that vessel occlusion or the sealing of an aneurysm will be maintained over time.Type: ApplicationFiled: August 17, 2021Publication date: February 3, 2022Inventors: F. Nicholas Franano, Katherine J. Stephenson

Patent number: 11090176Abstract: A medical device comprising a compressed, inflatable, detachable single-lobed metal balloon attached to a catheter and methods of use for occluding blood vessels or treating vascular aneurysms are disclosed. The balloon can be made with ductile metals such as gold, platinum, or silver so that the balloon will conform to the shape of the void space during inflation and so that the balloon can be subsequently shaped by the application of an external force. The balloon can be configured such that it can be detached from the catheter by physical means or by electrolysis. The surface of the balloon can be configured to promote the growth of tissue into the wall of the balloon and to release drugs or pharmacologically active molecules, so that vessel occlusion or the sealing of an aneurysm will be maintained over time.Type: GrantFiled: January 17, 2012Date of Patent: August 17, 2021Assignee: Artio Medical, Inc.Inventors: F. Nicholas Franano, Katherine J. Stephenson

Publication number: 20200163784Abstract: What is disclosed is a medical device comprising a compressed, cylindrical or oblong, thin-walled, expandable metal structure (a “blockstent”) and a flexible, elongated device (a “delivery catheter”) to position the compressed blockstent into the lumen of a blood vessel segment to be treated, and methods of use for occlusion of treated blood vessel segments. A blockstent can be made with ductile metals such as gold, platinum, or silver such that the blockstent will conform to the shape of the lumen of the treated blood vessel segment during expansion and allow for the shape of the blockstent to be permanently changed by the application of an external force. The surface of the blockstent can be configured to promote local thrombus on the external surface of the blockstent and to promote the growth of tissue into the wall of the blockstent in order to occlude the treated blood vessel and fix the blockstent in place.Type: ApplicationFiled: January 28, 2020Publication date: May 28, 2020Inventors: F.
