Patent number: 11724095Abstract: The disclosure relates to devices and methods for the treatment of edema using a purge-free system. The invention provides devices and methods useful for treating edema by means of an indwelling catheter that is placed in a blood vessel of a patient and used to pump blood to cause a decrease in pressure at an outlet of a lymphatic duct. The catheter pumps blood by means of an impeller but is purge-free in that the catheter does not include a system for purging or flushing catheter components with a purge fluid. The purge-free catheter avoids blood-related mechanical complications such as clotting or thrombosis by means of an impermeable sleeve or shroud that protects moving parts of the impeller drive system.Type: GrantFiled: February 26, 2020Date of Patent: August 15, 2023Assignee: White Swell Medical LtdInventors: Yaacov Nitzan, Ronan Keating, Shahaf Marmur, Or Inbar, Eamon Brady, Gerry McCaffrey, Reed Williston, Sagi Raz

Patent number: 11717652Abstract: The disclosure relates to devices and methods for the treatment of edema, which devices use a restrictor for flow compensation. Devices and methods of the invention further use a flow-restrictor in the circulatory system, upstream of an intravascular pump, to balance pressure changes induced by the pump and to compensate for downstream flow. The device may be provided as an indwelling, intravascular catheter with a mechanical pump such as an impeller and a selectively deployable restrictor such as an inflatable balloon. Congestive heart failure or edema is treated by \ operating the pump in an innominate vein and using the restrictor for flow compensation, to restrict the upstream flow and thus amplify or maintain pressure reduction at the lymphatic outlet.Type: GrantFiled: February 26, 2020Date of Patent: August 8, 2023Assignee: White Swell Medical LtdInventors: Yaacov Nitzan, Ronan Keating, Shahaf Marmur, Or Inbar, Eamon Brady, Gerry McCaffrey, Reed Williston, Sagi Raz

Publication number: 20230211084Abstract: Systems, and methods relate to a medical device receiving a treatment parameter operating point within a first operating region defined by a first set of operating points for which automatic incremental adjustment of a parameter in the current operation is permitted. In an illustrative example, incremental adjustment may use artificial intelligence based on patient feedback and sensor measurement of outcomes. Some exemplary devices may receive a request to alter the current treatment parameter operating point to a second treatment parameter operating point outside the first operating region and in a second operating region in a known safe operation zone, bounded by a known unsafe zone unavailable to the user. In the second operating region, some examples may restrict the step size of incremental adjustments requested by the user. Data may be collected for cloud-based analysis, for example, to facilitate discovery of more effective treatment protocols.Type: ApplicationFiled: March 14, 2023Publication date: July 6, 2023Applicant: White Bear Medical, LLCInventors: Ryan J.

Patent number: 11660426Abstract: The disclosure relates to devices and methods for the treatment of edema that uses an impeller with a balloon that may be mounted on the impeller housing. The invention provides devices and methods for treatment of edema that use an indwelling catheter with an impeller to lower pressure at an outlet of a lymphatic duct and a balloon on the impeller to guide and to restrict blood flow. The balloon restricts return flow from the jugular and guides that flow into the impeller cage. By funneling the flow into the impeller cage, a rate of flow down the vessel may be increased, resulting in a lateral pressure decrease effecting the lymphatic outlet. Because the lymphatic outlet is subject to a pressure decrease, fluids in the lymphatic system drain to the outlet and into the circulatory system.Type: GrantFiled: February 26, 2020Date of Patent: May 30, 2023Assignee: White Swell Medical LtdInventors: Yaacov Nitzan, Ronan Keating, Shahaf Marmur, Or Inbar, Eamon Brady, Gerry McCaffrey, Reed Williston, Sagi Raz
