Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically controllable redistribution component attachable to the patient to provide redistribution of the cardiac output to increase supply to the brain and heart. The redistribution component, following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patent; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage. Also disclosed is a method for providing resuscitation or suspended state.

A method, device, or system for treating eye disorders or conditions, comprising restoring or increasing blood flow or blood flow rate in an artery that supplies blood to or in the eye, thereby increasing the amount of nutrient(s) that reaches the eye or a portion thereof. The invention also includes methods, devices, or systems for treating eye disorders or conditions which use reverse flow or retrograde flow structures and systems during the treatment of the eye disease.

An example of recovery catheter assembly comprises an actuator element and a mechanically radially expandable and contractible recovery device operably connected to the actuator element. The recovery device has proximal and distal blocking portions and a central portion therebetween. The recovery device is at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the actuator element. When in the second, radially expanded configuration, the proximal and distal blocking portions have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion.

A control system controlling the blood flow rate in a blood supply system (1) in which a pump (18) transports blood from a reservoir (10) toward multiple outlets (30, 26, 26a) of which one or more outlets are openable to permit flow and closable to block flow, wherein the control system comprises a monitoring arrangement (22, 32, 32a) to determine the flow rate through a first outlet (30), and a controller responsive to the monitoring arrangement and controlling the pump (18) to maintain the flow rate through the first outlet (30) at a pre-determined level. This allows a flow rate through the first outlet to be maintained independently of any active blood diversions.

A veno-arterial extracorporeal membrane oxygenation system includes a dual lumen drainage cannula configured for withdrawing blood from a patient's vasculature in a manner that provides a perfusion of oxygenated blood with reduced carbon dioxide content while unloading the left ventricle, with two points of access to the patient's vasculature. The dual lumen drainage cannula has a first drainage tube and a second drainage tube co-axially aligned with the first drainage tube. The first and second drainage tubes are fluidly coupled to a connector. A blood pump having a pump inlet is configured for fluidly connecting with the connector, while an oxygenator having an oxygenator inlet is configured for fluidly connecting with a pump outlet. An infusion cannula is configured for fluidly connecting with an oxygenator outlet for infusing oxygenated blood into a patient's bloodstream.

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.
