Patent number: 11324619Abstract: The acute and chronic devices and methods described herein include a body lumen fluid flow modulator including an upstream flow accelerator and a downstream flow decelerator. The fluid flow modulator preferably includes one or more openings that define a gap/entrainment region that provides a pathway through which additional fluid from a branch lumen(s) is entrained into the fluid stream flowing from the upstream flow accelerator to the downstream flow decelerator. Delivery devices including a sheath and inner assembly also are provided for delivering the flow modulator to the body lumen. The delivery device may maintain the flow modulator in its collapsed, delivery state upon retraction of the sheath for ease of readjustment within the body lumen prior to full deployment of the flow modulator within the body lumen.Type: GrantFiled: December 27, 2021Date of Patent: May 10, 2022Assignee: Nephronyx Ltd.Inventors: Menashe Yacoby, Oren Rotman, Sagy Karavany, Tanhum Feld, Eyal Teichman

Publication number: 20220071788Abstract: 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.

Publication number: 20220039803Abstract: Various systems and methods are provided for reducing pressure at an outflow of a duct such as the thoracic duct or the lymphatic duct. In one embodiment, an indwelling catheter can be configured to be at least partially implanted within a vein of a patient in the vicinity of an outflow port of a duct of the lymphatic system. The catheter can include first and second restrictors each configured to at least partially occlude the vein within which the catheter is implanted and thus to restrict fluid flow within the vein when the restrictors are activated. The restrictors can each be configured to move between an activated configuration, in which the restrictor occludes the vein, and a relaxed configuration, in which the restrictor does not occlude the vein. The catheter can include a pump, such as an axial motor pump, configured to pump fluid through the catheter.Type: ApplicationFiled: October 25, 2021Publication date: February 10, 2022Inventors: Yaacov Nitzan, Menashe Yacoby, Tanhum Feld

Patent number: 11179552Abstract: Systems, methods, and devices are provided for the treatment of edema. In one aspect a method for implanting an indwelling catheter within a vein of a patient is provided. The catheter can extend from a position upstream of at least one outflow port of a duct of the lymph system to a terminal position downstream of the at least one outflow port. In use, a first restriction can be created within the vein proximal to a distal region of the catheter. The first restriction can define a localized low pressure zone distal of the restriction and within a portion of the vein housing the catheter. The low pressure zone can be adjacent to the at least one outflow port to enable fluid to pass from the at least one lymph duct outflow port into the vein.Type: GrantFiled: April 9, 2020Date of Patent: November 23, 2021Assignee: White Swell Medical LtdInventors: Yaacov Nitzan, Menashe Yacoby, Tanhum Feld

Patent number: 11033276Abstract: Methods and devices are used to treat a dorsal vein to reduce blood flow in patients suffering from erectile dysfunction. For example, a clip may be advanced distally across the deep dorsal vein and an anchor on the clip deployed on a proximal side of the Tunica albuginea. The clip can then be pulled back and a distal anchor on the clip deployed to reduce a cross-sectional area of the deep dorsal vein and anchor the deep dorsal vein to the Tunica albuginea. Anchoring of the dorsal vein to the Tunica albuginea further reduces the cross-sectional area of the deep dorsal vein in response to expansion of the patient's corpora cavernosa.Type: GrantFiled: June 7, 2019Date of Patent: June 15, 2021Assignee: Sano V Pte LtdInventors: Eitan Konstantino, Michal Konstantino, Tanhum Feld, Gary Binyamin
