Patent number: 11202701Abstract: A stent for placement in a blood vessel with a wall having an aneurysm including an endovascular graft having a first end, a second end, and a tubular body that is expandable and extends from the first end to the second end. The stent also includes a coagulation apparatus attached to the tubular body between the first and second ends. The coagulation apparatus has a frame and a coagulant attached to the frame. When the stent is deployed within the blood vessel, the tubular body extends across the aneurysm and expands at the first and second ends to seal against the wall of the blood vessel such that blood is channeled across the aneurysm through the tubular body such that a pocket of blood is defined external to the tubular body. The frame expands into the pocket to orient the coagulant therein and promote coagulation of blood within the pocket.Type: GrantFiled: June 30, 2017Date of Patent: December 21, 2021Assignee: Washington UniversityInventors: Eric C. Leuthardt, Greg Zipfel, Colin Derdeyn, Chandu Vemuri, Philip V. Bayly, Guy Genin, Katie McCoy, Junwoo Suh, Yuni Teh, Alan Zhao, Donald Elbert

Patent number: 10625068Abstract: A breakaway connector generally includes a first valve having a first rotating-type fluid control member, and a second valve that is attachable to the first valve and has a second rotating-type fluid control member. Each of the fluid control members has an open position in which fluid is permitted to flow through the respective valve, and a closed position in which fluid is prevented from flowing through the respective valve. Each one of the valves is configured to engage the fluid control member of the other one of the valves to move the fluid control member from the open position to the closed position upon detachment of the valves from one another.Type: GrantFiled: February 23, 2016Date of Patent: April 21, 2020Assignee: Washington UniversityInventors: Eric Leuthardt, Guy Genin, Eric Arias, James Norlin, Brittany Scheid, Chandu Vemuri, Ralph Dacey, Colin Derdeyn, Gregory Zipfel, Albert Kim, Philip Bayly, Srikanth Singamaneni, Lihong Wang

Publication number: 20190175372Abstract: An electronic intravascular device is placed in tight contact with vessel walls and is used for electrical stimulation and/or electrical recording of the vessel wall and surrounding target tissue. The electrodes may operate via connectors interfacing them to external hardware or may incorporate electronics to allow wireless power, information transfer, and control. The device includes an internal skeleton, a flexible substrate attached to the exterior of the skeleton, at least one pair of electrodes located on the substrate, and power and control circuitry connected to the electrodes. The power and control circuitry may include connectors for direct powering of the electrodes or circuit elements for wireless powering of the device by RF-based, optical-based, ultrasound-based, piezoelectric, or vibrational energy harvesting methods.Type: ApplicationFiled: July 23, 2018Publication date: June 13, 2019Applicants: Massachusetts Institute of Technology, Washington UniversityInventors: Edward Stuart Boyden, Giovanni Talei Franzesi, Christian Wentz, Nir Grossman, Elazer R. Edelman, Colin Derdeyn, Eric Leuthardt
