Patent number: 11865023Abstract: Apparatus and methods are described including implanting an aortic pressure-loss-reduction device in a subject's ascending aorta. While the device is inside a catheter, a distal end of the catheter is placed within the ascending aorta. A proximal covering sheath of the catheter is retracted such as to uncover at least a portion of a downstream anchor, such that the uncovered portion of the downstream anchor includes a portion of the frame that does not have material coupled thereto. Subsequently, a distal covering sheath of the catheter is advanced, such as to cause an upstream anchor to anchor an upstream end device to the subject's ascending aorta, by the upstream anchor radially expanding against an inner wall of the ascending aorta. Other applications are also described.Type: GrantFiled: November 15, 2021Date of Patent: January 9, 2024Assignee: HEMODYNAMX-TECHNOLOGIES LTD.Inventors: Sagy Karavany, Menashe Yacoby, Tanhum Feld

Patent number: 11357610Abstract: Apparatus and methods are described for regulating blood flow in an ascending aorta of a subject including inserting a device into the ascending aorta. When in a deployed state, the device defines an inner surface that defines a conduit through the device, at least a portion of the inner surface diverging, such that a cross-sectional area of the conduit at the downstream end of the diverging portion is greater than a cross-sectional area of the conduit at the upstream end of the diverging portion. The device is deployed within a longitudinal portion of the ascending aorta, such that the device defines the conduit throughout deployment of the device within the longitudinal portion of the ascending aorta. Other applications are also described.Type: GrantFiled: January 15, 2020Date of Patent: June 14, 2022Assignee: HEMODYNAMX-TECHNOLOGIES LTD.Inventors: Sagy Karavany, Tanhum Feld, Boaz Nishri

Patent number: 11207200Abstract: Apparatus and methods are described including implanting an aortic pressure-loss-reduction device (20) in a subject's ascending aorta. While the device is inside a catheter (42), a distal end of the catheter is placed within the ascending aorta. A proximal covering sheath (44) of the catheter is retracted such as to uncover at least a portion of a downstream anchor (31), such that the uncovered portion of the downstream anchor includes a portion of the frame that does not have material coupled thereto. Subsequently, a distal covering sheath (45) of the catheter is advanced, such as to cause an upstream anchor (33) to anchor an upstream end device (20) to the subject's ascending aorta, by the upstream anchor radially expending against an inner wall of the ascending aorta. Other applications are also described.Type: GrantFiled: November 14, 2018Date of Patent: December 28, 2021Assignee: HEMODYNAMX-TECHNOLOGIES LTD.Inventors: Sagy Karavany, Menashe Yacoby, Tanhum Feld

Patent number: 10568731Abstract: Apparatus and methods are described for regulating blood flow in an ascending aorta of a subject including inserting a device (20) into the ascending aorta. When in a deployed state, the device defines an inner surface (24) that defines a conduit (26) through the device, at least a portion (25) of the inner surface diverging, such that a cross-sectional area of the conduit at the downstream end (34) of the diverging portion is greater than a cross-sectional area of the conduit at the upstream end (30) of the diverging portion. The device is deployed within a longitudinal portion of the ascending aorta, such that blood flow through the portion of the ascending aorta, via any flow path other than through the conduit, is less than 20 percent of total blood flow through the portion of the ascending aorta. Other applications are also described.Type: GrantFiled: February 11, 2016Date of Patent: February 25, 2020Assignee: HEMODYNAMX-TECHNOLOGIES LTD.Inventors: Sagy Karavany, Tanhum Feld, Boaz Nishri

Patent number: 10195406Abstract: The devices and methods described herein include an implantable body lumen fluid flow modulator including an upstream flow accelerator separated by a gap from a downstream flow decelerator. The gap is a pathway to entrain additional fluid from a branch lumen(s) into the fluid stream flowing from the upstream flow accelerator to the downstream flow decelerator.Type: GrantFiled: May 31, 2018Date of Patent: February 5, 2019Assignee: HemoDynamx Technologies, Ltd.Inventors: Sagy Karavany, Eyal Teichman
