The present disclosure provides for methods and systems for determining heart rate of a patient. Based on motor current signals of a ventricular assist device (VAD), each of first, second and third events in the measured current signal may be detected, the first event being indicative of a rise or fall in the current signal, the second event being indicative of a rise or fall in the current signal in the opposite direction as the first event, and the third event being indicative of a rise or fall in the current signal in the same direction as the first event. A timer counter may be initiated upon detection of the first event, and an elapsed time may be measured upon detection of the third event. Heart rate may be determined based on the elapsed time of the timer counter.

An implantable controller for an implantable medical device includes a metallic housing defining an enclosure. Processing circuitry is disposed within the enclosure and configured to control operation of the implantable medical device. A first aluminum encasement is disposed within the enclosure. A first piece of graphite is disposed within the aluminum encasement. A pressure sensitive adhesive is disposed between an internal surface of the metallic housing and the aluminum encasement.

An operable implant adapted to be implanted in the body of a patient. The operable implant comprising an operation device and a body engaging portion, the operation device comprises an electrical motor comprising a static part comprising a plurality of coils and a movable part comprising a plurality of magnets, such that sequential energizing of said coils magnetically propels the magnets and thus propels the movable part. The operation device further comprises an enclosure adapted to hermetically enclose the coils of the static part, such that a seal is created between the static part and the propelled moving part with the included magnets, such that the coils of the static part are sealed from the bodily fluids, when implanted.

A blood pumping device is described having at least a first pump and a first pump actuator for inducing a blood flow in a body's circulatory system. The pump has one upper chamber having an inlet channel and one lower chamber having an outlet channel. The upper and lower chambers are separated by a movable valve plane provided with a one-way valve. The pump actuator induces movement of the valve plane in an upward and downward direction between the upper and lower chambers in response to control signals from a control unit. When the valve plane moves in an upward direction, the valve opens allowing a flow of blood from the upper to the lower chamber. The lower chamber is provided with a bag-like portion forcing said flow of blood to make a turn of between 110° to 150° before leaving through the outlet channel.

The present invention relates to a transcatheter method for providing fluid communication between two anatomical compartments. The present invention also relates to a transcatheter system comprising an intracorporeal connector for fluid communication between two anatomical compartments through at least one anatomical wall, wherein said connector is adapted to receive a flow regulating device, a connector, a flow regulating device and an insertion device.

The present invention concerns a device for the ventricular emergency support, comprising: a first flexible catheter (2), with a variable transversal section, provided with an extremal balloon (7) for the controlled occlusion of the ascending aorta (AA) of the treated patient; a first pump (12), associated to said first catheter (2) for the aspiration and contemporary input of equivalent blood quantifies into the blood circle of the treated patient; a second flexible catheter (32), with a fixed transversal section, provided with a couple of extremal balloons (34), spaced apart, for the controlled occlusion of the inferior vena cava (CA) and of the superior vena cava (CD) of the treated patient; a second pump (35), associated to said first and second catheter (2, 32) for inflating and deflating said extremal balloons (7, 34) of said first and second catheter (2, 32); an electronic control unit (36) for adjusting and controlling the operational parameters of said first and second pump (12, 35), and for the detection of the cardiac parameters of the treated patient; rechargeable or network means (37, 38) for the power supply of above mentioned components.

Mechanical circulatory supports configured to operate in series with the native heart are disclosed. In an embodiment, an intravascular propeller is installed into the descending aorta and anchored within via an expandable anchoring mechanism. The propeller and anchoring mechanism may be foldable so as to be percutaneously deliverable to the aorta. The propeller may have foldable blades. The blades may be magnetic and may be driven by a concentric electromagnetic stator circumferentially outside the magnetic blades. The stator may be intravascular or may be configured to be installed around the outer circumference of the blood vessel. The support may create a pressure rise between about 20-50 mmHg, and maintain a flow rate of about 5 L/min. The support may have one or more pairs of contra-rotating propellers to modulate the tangential velocity of the blood flow. The support may have static pre-swirlers and or de-swirlers. The support may be optimized to replicate naturally occurring vortex formation within the descending aorta.
