Patent number: 11166730Abstract: 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: GrantFiled: April 2, 2019Date of Patent: November 9, 2021Assignee: White Swell Medical LtdInventors: Yaacov Nitzan, Menashe Yacoby, Tanhum Feld

Patent number: 11123482Abstract: A method of embolizing a tumor includes advancing a distal end of a device having a catheter body and an occlusion structure to a target tumor site within a blood vessel of a body. The occlusion structure is activated within the blood vessel, and a real time pressure measurement in the vascular space distal to the activated occlusion structure is monitored. The method further includes waiting for a pressure drop in the vascular space distal to the activated occlusion structure and for the pressure drop to cause a blood flow reversal in branch vessels antegrade to the occlusion. An embolic substance is injected from the distal end of the delivery device to permit the reversed blood flow to carry the embolic substance into the vasculature of the target tumor and the device is withdrawn from the body. Other catheter assemblies and methods of use are also disclosed.Type: GrantFiled: November 20, 2018Date of Patent: September 21, 2021Assignee: Embolx, Inc.Inventor: Michael P. Allen
