Devices, systems, and methods for providing retroperfusion to at least one ischemic tissue in a minimally invasive manner are disclosed. At least some of the embodiments disclosed herein enable an anastomosis to be formed between a vein and an artery without the use of sutures and through a non-invasive procedure. In addition, various disclosed embodiments provide a cannula device comprising a Y-configuration for bifurcating arterial flow between an anastomosis and the underlying artery. The devices, systems and methods herein can further provide simultaneous autoretroperfusion therapy to more than one area of an ischemic tissue.

A by-pass shunt for use with a bodily fluid pump. The by-pass shunt includes an inflow conduit, an outflow conduit, and an intermediate conduit fluidically coupling the inflow and outflow conduits. A flow restrictor is operably coupled to a portion of the intermediate conduit and is configured to reduce a fluid flow from the outflow conduit, through the intermediate conduit, and into the inflow conduit.

A method of managing a speed of implantable blood pump. The implantable blood pump is in communication with an internal battery and a transcutaneous energy transfer system (TETS). The method includes starting the pump at a programmed set speed. The speed of the pump is decreased from the programmed set speed to a minimum set speed if either a capacity of the internal battery is less than a predetermined reserve level and TETS power is unavailable, or there is insufficient TETS power to maintain the programmed set speed. The speed of the pump is progressively decreased from the programmed set speed if there is insufficient power to maintain the programmed set speed.

The invention relates to a system (100) and a method (500) for controlling a cardiac support system (10), comprising a first extracorporeal control device (110), wherein the first control device (110) is or can be connected to the cardiac support system (10) with a wire or a first coil (150) for communication and/or energy transfer, and comprising a second extracorporeal control device (120) which is wirelessly connected to the first control device (110). The invention also relates to a cardiac support system (10) having a control system according to the invention (100).

Systems and methods for generating blood flow with a pump incorporating linear bearing technology are provided. The pump may include an actuator assembly, a moving assembly, and a linear hydrodynamic or thin-film bearing positioned within a housing. The moving assembly may include at least one magnet and the actuator assembly may include a magnetic assembly for selectively generating a magnetic field to cause linear reciprocating movement of the moving assembly with respect to the actuator assembly. The linear hydrodynamic or thin-film bearing may include a bearing portion on the moving assembly that is in fluid communication with a bearing portion on the actuator assembly or pump housing. The system may involve an implantable pump, an extracorporeal battery and a controller coupled to the implantable pump. The implantable pump may be suitable for use as a left ventricular assist device (LVAD).

The present disclosure relates to an improved transcutaneous energy transfer (TET) system that generates and wirelessly transmits a sufficient amount of energy to power one or more implanted devices, including a heart pump, while maintaining the system's efficiency, safety, and overall convenience of use. The disclosure further relates one or more methods of operation for the improved system.

A method of determining adverse events from log file data from operation of an implantable blood pump. The method includes measuring a flow pulsatility from flow rate data recorded in a log file. A moving mean of the measured flow pulsatility is calculated. A moving standard deviation of the measured flow pulsatility is calculated. A difference between the moving mean of the measured pulsatility and the moving standard deviation of the measured flow pulsatility is calculated. If the difference is less than a first predetermined threshold, an alert is generated as the presence of an adverse event.

Disclosed is a physiologic monitoring system comprising a central hub in communication with a management portal for communicating physiologic measurements taken from a plurality of peripheral devices on a patient. At least one non-invasive peripheral device may measure physiologic data from a patient and be in communication with said central hub. A system including an invasive peripheral device may be associated with said patient and be in communication with said central hub. The central hub may be scalable to collect and communicate measurements from the non-invasive peripheral device and the invasive peripheral device. The at least one non-invasive peripheral device may include a blood pressure cuff, an oxygen sensor, a weight scale, and an ECG monitor. The invasive peripheral device may include a wireless sensor reader that may be adapted to measure physiologic data from a sensor implant placed within the cardiovascular system of said patient.
