A controller for an implantable blood pump includes processing circuitry configured to initiate a suction response algorithm if a combination of a number of detected suction events multiplied by a suction event variable and a number of non-suction events multiplied by a non-suction event variable exceed a predetermined threshold.

The present invention generally relates to heart treatment systems. In some aspects, methods and systems are provided for facilitating communication between implanted devices. For example, an implantable cardiac rhythm management device may be configured to communicate with an implantable blood pump. The implantable cardiac rhythm management device may deliver heart stimulation rate information in addition to information associated with any detected abnormalities in heart function. In response, the pump may be configured to adjust pumping by the pump to better accommodate a patient's particular needs.

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.

Systems and methods for controlling fluid delivery via a manually administrable medication container to a patient through a fluid delivery pathway are provided. The systems and methods described herein incorporate rules-based clinical decision support logic to drive a flow control valve within a flow pathway based on a determination of whether or not an IV fluid connected to an input port on the pathway is appropriate for patient administration by considering such factors as patient-specific clinical circumstances, current medical orders, and accepted delivery protocols. Related apparatus, systems, methods and articles are also described.

A catheter pump assembly is provided. The catheter pump assembly includes a proximal portion, a distal portion, a catheter body having a lumen extending along a longitudinal axis between the proximal and distal portions, an impeller disposed at the distal portion, and a stator disposed at a downstream location of the impeller to straighten flow downstream from the impeller. The stator is collapsible from a deployed configuration to a collapsed configuration.

A connector assembly for use in a medical device system is provided. The connector assembly includes a female connector including a jack and at least one female electrical contact disposed in the jack, where the at least one female electrical contact includes an outer ring and leaf springs extending both radially inward from the outer ring and longitudinally along the jack. The connector assembly also includes a male connector including a plug adapted to be inserted into the jack of the female connector, and at least one male electrical contact disposed on the plug, where the at least one male electrical contact is configured to electrically couple to a corresponding female electrical contact of the at least one female electrical contact by contacting the plurality of leaf springs of the corresponding female electrical contact when the plug of the male connector is inserted into the jack of the female connector.

A controller implantable within the body of a patient as part of a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, the controller includes processing circuitry configured to receive inputs from at least one of: at least one internal component of the LVAD system, at least one external component of the LVAD system, and at least one clinician's device, and determine a charging rate for charging a battery of the LVAD system internal to the patient based on at least one of the received inputs.
