Publication number: 20210077283Abstract: An implantable frame comprises a plurality of corner structures configured to decrease pressure to the vessel wall and define pulsatility enhancing windows of the implantable frame. The corner structures may comprise plurality of neighboring longitudinal struts that extend in a longitudinal direction of the blood vessel when placed to form the vessel wall to a substantially polygonal cross-section and distribute pressure loading of the corner structure among the plurality of neighboring longitudinal struts to improve biocompatibility. The corner structures also allow increased forming of the vessel wall and can provide stretching of the vessel wall to enhance pulsatility of the vessel wall.Type: ApplicationFiled: August 28, 2020Publication date: March 18, 2021Inventors: Chung Hao Yeh, Jennifer Gong, Brent Seybold, Christopher Ken, Suji Shetty, Edward F.

Patent number: 10653513Abstract: Systems and methods for screening a subject for a therapy are described. A mechanical stimulation device positioned near at target location of a blood vessel to provide a mechanical stimulus to the blood vessel. The mechanical stimulus increases strain in one or more regions of the blood vessel, such as by modifying the cross-sectional geometry and/or area of the blood vessel to have different regions of different curvature A baroreflex or related physiological response in response to the mechanical stimulation is detected. In response to the detected response, it is determined whether the subject is appropriate for the therapy and/or which of a plurality of implants with different geometries and/or cross-sectional areas is most optimally suited for deployment in the subject.Type: GrantFiled: February 21, 2018Date of Patent: May 19, 2020Assignee: Vascular Dynamics, Inc.Inventors: Brent Seybold, Christopher Ken, Jennifer Gong, Suji Shetty, Robert Stern, Edmund Roschak

Patent number: 9072596Abstract: An apparatus method for establishing a Transjugular Intrahepatic Portosystemic Shunt between the portal vein from a hepatic vein. The apparatus comprises an elongated hollow outer guide; an outer handle having an inner lumen and a first luer lock, the outer handle attached at a proximal end of the outer guide, the outer guide in flow communication with the inner lumen and the luer lock; an elongated hollow inner needle; and a hub having a second luer lock, the hub attached at a proximal end of the inner needle, the inner needle in flow communication with the second luer lock. The inner needle is slidingly received into the outer guide through the inner lumen. The inner needle is configured to rotate within the outer guide by manipulation of the hub; and a distal tip of the inner needle is deployed out of and beyond a distal tip of the outer guide.Type: GrantFiled: October 15, 2012Date of Patent: July 7, 2015Inventors: Sidney Lowell Kahn, Wael Saad, Brent Seybold

Publication number: 20130304102Abstract: Stimulation of a stretch receptor response to the cardiac cycle is enhanced by constraining a region of a blood vessel wall upstream and/or downstream of a baroreceptor. The constraint may be external or internal and will typically be effected using a circumferential restraint placed over or within the blood vessel.Type: ApplicationFiled: May 8, 2013Publication date: November 14, 2013Applicant: Vascular Dynamics, Inc.Inventors: Yossi Gross, Chung Hao Yeh, Christopher Ken, Brent Seybold, Jennifer Gong

Patent number: 8287481Abstract: An apparatus method for establishing a Transjugular Intrahepatic Portosystemic Shunt (“TIPS”) between the portal vein from a hepatic vein. The apparatus comprises a multi-needle TIPS device designed to facilitate safer and more rapid catheterization of the portal vein. The method utilizes the multi-needle TIPS device to access the portal vein from the hepatic vein approach. The multi-needle TIPS device and method provides numerous benefits over previous TIPS devices and procedures and results in shorter and safer procedures. Use of multiple needles increases the probability of finding the portal vein more quickly.Type: GrantFiled: December 22, 2009Date of Patent: October 16, 2012Inventors: Sidney Lowell Kahn, Wael Saad, Brent Seybold

Publication number: 20060094930Abstract: A catheter system and corresponding methods are provided for accessing a blood vessel true lumen from a sub-intimal plane of the vessel. The catheter system includes visualization elements for determining the orientation of the true lumen with respect to the sub-intimal plane at an identified entry site from a position in the sub-intimal plane. The entry site is distal to a chronic total occlusion (CTO). The catheter system also includes a system for physically securing tissue of the sub-intimal plane at the entry site to the catheter system. The attaching system reduces or eliminates catheter float within the sub-intimal space. The catheter system further includes re-entry devices to establish and maintain a path from the sub-intimal plane back into the vessel true lumen.Type: ApplicationFiled: December 13, 2005Publication date: May 4, 2006Inventors: Kurt Sparks, Jeffrey Emery, Brent Seybold, David Kupiecki, C. Pinson, Allen Madsen, Michael Keleher, Sergio Salinas, Benjamin Clark, Matthew Selmon
