  • Publication number: 20200230308
    Abstract: A veno-arterial extracorporeal membrane oxygenation system includes a dual lumen drainage cannula configured for withdrawing blood from a patient's vasculature in a manner that provides a perfusion of oxygenated blood with reduced carbon dioxide content while unloading the left ventricle, with two points of access to the patient's vasculature. The dual lumen drainage cannula has a first drainage tube and a second drainage tube co-axially aligned with the first drainage tube. The first and second drainage tubes are fluidly coupled to a connector. A blood pump having a pump inlet is configured for fluidly connecting with the connector, while an oxygenator having an oxygenator inlet is configured for fluidly connecting with a pump outlet. An infusion cannula is configured for fluidly connecting with an oxygenator outlet for infusing oxygenated blood into a patient's bloodstream.

  • Publication number: 20170014159
    Abstract: Provided herein is a catheter assembly including an imaging device for identifying an anatomical structure. The catheter assembly includes a patient cannula configured to be drawn along a catheter or guide wire; a transseptal puncture catheter at least partially enclosed within the patient cannula; and an imaging catheter. The imaging catheter includes a transducer configured to emit an energy beam capable of reflecting from an anatomical structure and to detect energy reflected from the structure. The catheter assembly also includes a transmitter for conveying a signal representative of the detected energy from the transducer to a signal processor for obtaining information about the structure. An imagining system and a method for identifying a predetermined transseptal puncture location on an atrial septum are also provided herein.

  • Patent number: 8945051
    Abstract: A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes a powered injector, a pressure jacket support, a syringe pressure jacket, and a syringe. The pressure jacket support includes a front plate and a rear plate. The rear plate is connected to the injector and the front plate is spaced from the rear plate and defines a slot. The syringe pressure jacket has a proximal end pivotally connected to the rear plate so that a distal end of the pressure jacket pivots relative to the front plate. The syringe has a syringe body with a distally extending discharge conduit. With the syringe disposed in a barrel of the pressure jacket, pivotal movement of the pressure jacket results in the distal end thereof pivoting toward the front plate to place the discharge conduit within the slot in the front plate.

  • Patent number: 8808253
    Abstract: The fluid injector system includes a source of injection fluid, a pump device, and a fluid path set in fluid connection with the source of injection fluid and the pump device. The fluid path set includes a drip chamber including an elongated body having a raised projection from substantially a top end to substantially a bottom end, the elongated body configured to receive and contain the injection fluid. A fluid level sensing mechanism is operably associated with a fluid control device, and includes a support for the drip chamber body, wherein the support is adapted such that the raised projection is in operational contact with a fluid level sensor associated with the support. The fluid level sensing mechanism is operable to transmit ultrasonic or light energy through the raised projection to be sensed by the fluid level sensor for sensing the injection fluid level in the drip chamber.
