  • Patent number: 10239681
    Abstract: A drum unloader may include a pump assembly, a motor, a plate, a piston-cylinder assembly, and a sensor. The motor drives the pump assembly. The plate is mounted to the pump assembly and includes an inlet to the pump assembly. The piston-cylinder assembly includes a housing, a piston, and a piston rod. The housing defines a bore. The piston is received within the bore and cooperates with the housing to define a first cavity and a second cavity. The piston rod is attached to and extends from the piston such that the piston rod extends through the first cavity. The piston rod is coupled to the pump assembly, the motor and the plate such that movement of the piston within the bore causes corresponding movement of the pump assembly, the motor and the plate relative to the housing. The sensor measures a pressure within the second cavity.

    Abstract: A medical device includes a pulse generator and a filter. The pulse generator is configured to generate a stimulation signal and to provide the stimulation signal to tissue of a patient via an implantable lead assembly. The filter is configured to couple to the implantable lead assembly. A combined impedance of the implantable lead assembly and the filter with respect to a current induced by an external electro-magnetic field satisfies an impedance threshold when the external electro-magnetic field has a first frequency and when the external electro-magnetic field has a second frequency. The combined impedance has a peak impedance value when the external electro-magnetic field has a third frequency that is between the first frequency and the second frequency.

  • Patent number: 9943685
    Abstract: According to aspects of the present disclosure, an implantable electrical system may include an implantable pulse generator with a bore sized to receive an electrical lead, with an engagement mechanism that does not require the use of set screws to secure the lead within the bore. The engagement mechanism may include a deformable component that may be moved or deformed to allow entry of the lead into the bore, and then moved or deformed again to engage a surface of the lead to secure the lead within the bore. The engagement mechanism may allow rotation of the lead within the bore while maintaining electrical connections between the generator and the lead. The engagement mechanism may also allow the securing and/or release of the lead relative to the bore without the need to manipulate a set screw or breach a seal of the generator.

  • Patent number: 9537344
    Abstract: A method and system for management of thermal energy produced during transcutaneous energy transmission to provide power to energize implanted medical devices. A phase changing material (PCM) acts as a heat sink to absorb thermal energy generated during the energy transfer process. The PCM can be thermally coupled to tissue proximate to an implanted medical device, enabling heat generated within the implantable device to be absorbed. The generation of heat during the energy transfer process is primarily caused by eddy currents induced in the implantable device by the magnetic flux produced by the energy transfer system. The PCM can also be used to absorb heat generated by the device producing the magnetic flux that is used to transcutaneously transfer electrical power to recharge a rechargeable power source or energize the implanted medical device.
