Abstract: An intravascular blood pump for percutaneous insertion comprises a catheter (10) and a pumping device (1) attached to the catheter (10). The catheter (10) extends along a longitudinal axis and has a distal end (11) and a proximal end (12) opposite the distal end (11). The catheter (10) comprises an elongate stiffening structure (15) extending continuously longitudinally along the length of the catheter (10) between the proximal end (11) and the distal end (12) of the catheter (10). The stiffening structure (15) may comprise a shape-memory material, such as Nitinol. It may be in the form of a wire that extends loosely through the lumen of the catheter and helps to avoid or significantly reduce kinks in the catheter.

Abstract: Systems and related methods for supplying power to a medical device employ serially-connectable portable batteries. A method of supplying electrical power to a medical device includes discharging a first external battery to output electrical power to a second external battery. Distribution of the electrical power received by the second external battery is controlled to simultaneously charge the second external battery and output electrical power from the second external battery to supply electrical power to the medical device.

Abstract: The present invention relates to a filtering device for removing particles from a bodily fluid of a patient, the filtering device being implantable in the patient's body. The device has a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid of the patient passes when the tube is implanted in the patient, a filter connected to the tube and a filter cleaning device for cleaning the filter by moving particles collected by the filter out of the fluid passageway, wherein the filter cleaning device is adapted to replace the first filter in the fluid passageway with a second filter, thereby moving the particles collected by the first filter out of the fluid passageway.

Abstract: A system for minimizing misalignment notifications for a TETS having an implantable blood pump, an external controller having a power source and a processing circuitry, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and the implantable blood pump. The implantable controller having a power source configured to receive power from the receiving coil. The processing circuitry may be configured to: operate in a first mode where an alert is generated when a power efficiency transfer between the transmission coil and the receiving coil is below a first predetermined threshold; and operate in a second mode where the alert is only generated when the power remaining in the power source for the implantable controller is below a first predetermined power source threshold.
