A percutaneous lead assembly for an active implantable device, the lead assembly comprising a sheath with a plurality of wires extending from a proximal end to a distal end. The wires being adapted to power the active implantable device; the distal end having at least one electrode fixed thereon. The electrodes being in communication with sensor electronics and wherein at least one electrode is on the outer layer of the lead assembly in which the electrode is used to detect at least one of acceleration and electrical signals of an organ.

An external controller assembly for a medical device implanted in a patient includes an external controller and an external driveline assembly. The external controller includes an external controller display viewable by the patient. The external driveline assembly includes an external driveline cable and an external driveline distal connector. The external driveline cable is connected to the external driveline distal connector and the external controller. The external driveline cable accommodates positioning of the external driveline distal connector, by the patient, for simultaneous viewing of the external driveline distal connector and the external controller display by the patient. The external driveline distal connector is adapted to be connected to the distal driveline proximal connector by the patient. The external driveline distal connector is adapted to be disconnected from the distal driveline proximal connector by the patient.

An inflow cannula assembly intended for connecting a ventricular assist device (VAD) to a heart chamber without suturing anastomosis is provided. The inflow cannula assembly includes a deformable flow cannula with funnel-shaped bellmouth intake at a first end and a second end interfaced to the inlet of a VAD with minimal interface discontinuity; also includes is a pair of male and female fasteners that can be screw locked to fix and seal the cannula bellmouth against the endocardium for hemostasis purpose; as well as a VAD coupler and a VAD inlet adapter that enable a quick connection of the cannula with the VAD.

A para-aortic blood pump device includes a blood pump, an aortic adapter, a driveline, and a driver. The blood pump includes a blood sac, a pump housing and a pressure sensor, whereas the pressure sensor is installed in the pump housing for monitoring the blood pressure inside the blood pump. The aortic adapter is a T-manifold shaped conduit connected to the blood pump and is used for connecting the blood pump with human aorta to facilitate circulatory support. The driveline allows a pneumatic communication to the blood pump in addition to transmitting the electrical blood pressure signal to the driver. The driver receives and processes the electrical blood pressure signal, decides the timing, speed and duration of blood pump fill and eject actions so as to provide counter-pulsatile circulatory support to assist human circulation.

An implantable circulatory support system, configured to connect a ventricular chamber of a heart, including a valveless displacement blood pump, a deformable polymeric flow cannula, a pair of male and female fasteners, a coupler, a driveline assembly, and a co-pulsatile driver. Forward and backward flow communication between the blood pump and the heart chamber is accomplished using the present flow cannula invention which is anastomosed to the heart chamber in a sutureless manner. When providing circulatory support, the co-pulsatile driver ejects blood out of the blood pump during systolic ventricular contraction and fills the blood pump with blood during diastolic ventricular relaxation.

An attachment mechanism between a controller for an implantable blood pump and a battery housing. The attachment mechanism includes a latch moveably coupled to the controller. The latch includes a pawl configured to engage the battery housing. The latch is configured to only pivot when the battery housing is engaged to the pawl during attachment of the battery housing to the controller.
