  • Publication number: 20210069479
    Abstract: A method for maintaining a balloon of a balloon catheter at a prescribed pressure of between about 0.2 psi and 1 psi comprises the step of: generating a vacuum within a reservoir defined in a burette that is part of a fluid management system that is configured to controllably inflating and deflating the balloon by circulating balloon fill media along a fluid circuit, wherein generating the vacuum results in formation of a pressure differential along the fluid circuit, thereby allowing the balloon to be maintained at the prescribed pressure between about 0.2 psi and about 1 psi.

  • Patent number: 10926067
    Abstract: Systems and methods for controlling fill media in a balloon catheter are disclosed. The system comprises a catheter having an inflatable balloon, a reservoir for fill media, and a first conduit for delivering fill media from the reservoir to the balloon. The system includes a second conduit for returning fill media from the balloon to the reservoir and a pump configured to circulate fill media through the conduits. The system also includes a valve assembly configured for placement in at least three positions. In the first position, fill media is delivered from the reservoir to the balloon to inflate the balloon. In the second position, fill media is drawn out of the balloon and returned to the reservoir. In the third position, fill media circulates through the conduits between the pump and the balloon and is prevented from flowing back to the reservoir.

  • Publication number: 20200315704
    Abstract: The present disclosure relates to ablation instruments and methods of use thereof, in particular to ablation catheters and methods for an automated sweeping ablation element. The automated sweeping ablation element is configured to provide ablative energy to an initial ablation site and move a predetermined number of degrees to one or both sides of the site in an arcuate path using a sweeping motion while still providing the ablative energy. The sweeping movement of the ablation element can be automated via input parameters entered by a user via a graphical user interface or other device (controller).

  • Publication number: 20190216540
    Abstract: An ablation instrument (e.g., an ablation balloon catheter system) includes an elongate catheter having a housing with a window formed therein. An energy emitter is coupled to the elongate catheter and is configured to deliver ablative energy. A controller is received within the window and is coupled to the energy emitter such that axial movement of the controller within the window is translated to axial movement of the energy emitter and rotation of the controller within the window is translated into rotation of the energy emitter. The instrument includes a motor that is at least partially disposed within the housing of the catheter; a first gear that is operatively connected to and driven by the motor; and a second gear that is coupled to the energy emitter and is driven by the first gear to cause rotation of the energy emitter, while allowing the energy emitter to move axially.

  • Publication number: 20180193612
    Abstract: A balloon catheter device with a fluid management system includes a source of balloon fill media and a balloon catheter in fluid communication with the source of balloon fill media. A first conduit is provided for delivering the balloon fill media from the source to the balloon catheter for inflation of a balloon of the catheter device. A second conduit is provided for returning the balloon fill media from the balloon catheter to the source for deflating the balloon. A first pump is disposed along one of the first conduit and the second conduit for pumping the balloon fill media through the respective conduits.

  • Patent number: 5935144
    Abstract: An ultrasonic surgical instrument is described for use in medical procedures to, for example, dissect or cut living organic tissue. The ultrasonic surgical instrument includes an outer sheath, a waveguide, and an improved acoustic isolation element. The acoustic isolation element is bonded to both the ultrasonic waveguide and the interior surface of the outer sheath, creating an acoustic isolation seal. The improved acoustic isolation element seals the distal end of the ultrasonic instrument, substantially improving its ability to reduce or eliminate penetration by liquids or other contaminants during, for example, soaking or steam autoclave sterilization.
