  • Patent number: 11506192
    Abstract: A pulsatile fluid pump apparatus includes an integral pump assembly employing a flexible diaphragm in a diaphragm assembly; a pulsatile fluid pump system including a control housing, for removably receiving the integral pump assembly, the control housing and the integral pump assembly being configured for operation, in a first mode, so that the pulsatile fluid pump system reciprocally actuates the diaphragm assembly to cause pumping automatically; and a manual driver assembly, wherein the integral pump assembly is configured, in a second mode, in the absence of actuation of the diaphragm assembly by the pulsatile fluid pump system, to removably receive the manual driver assembly to support manual actuation and operation of the diaphragm assembly.

  • Publication number: 20220265993
    Abstract: A pulsatile fluid pump system includes a pump-valving assembly including a chamber and a diaphragm assembly coupled to the chamber and including a flexible diaphragm. The diaphragm assembly and the pump-valving assembly are configured as an integral pump assembly. The system further includes a linear motor having a magnet and a coil, the magnet moving in relation to the coil, the coil having an electrical input. The system also includes a control housing rigidly coupled to the linear motor and a controller system having an electrical output coupled to the electrical input of the coil, the controller system defining an electrical waveform at the electrical output to cause desired operation of the diaphragm. The integral pump assembly is configured to be removably coupled to the control housing, and the diaphragm assembly of the integral pump assembly is configured to be removably coupled to the linear motor.

  • Publication number: 20190321093
    Abstract: Embodiments relate to illuminated electrosurgical devices and related systems and methods. An electrosurgical device can include an electrosurgical blade having a proximal end and a distal end and comprising a dielectric coating, at least one of the electrosurgical blade or the dielectric coating including at least one light-guiding element, an optic having a proximal end and a distal end, the distal end of the optic optically coupled to the proximal end of the electrosurgical blade, and a light source arranged at the proximal end of the optic and configured to provide light that is guided through the optic and the at least one light-guiding element to illuminate an area around the distal end of the electrosurgical blade.

  • Patent number: 7951107
    Abstract: A method and apparatus are provided for quickly connecting a handpiece to a pressurized fluid source. A hollow tube on the handpiece is inserted through an aperture in an annular gasket which is held in a chamber in a body. On application of pressurized fluid to the body, the gasket is pressed against the walls of the chamber, and against the tube, thereby channeling the pressurized fluid through the hollow tube. The handpiece is retained in connection with the body by a releasable connector, such as a latch. The handpiece can be removed and replaced by releasing and remaking the connection.
