  • Patent number: 11147651
    Abstract: According to various implementations, a dental cleaning device includes a steam conduit and a cooling fluid conduit. The steam conduit has a distal tip with an opening defined therein that allows steam to be applied intraorally close to a dental implant to flush away bacteria that has colonized on or adjacent the dental implant. The cooling fluid conduit has a distal tip with an opening defined therein that allows a cooling fluid to be applied intraorally close to the dental implant following the application of the steam to cool the tissue and prevent overheating of the tissue and bone adjacent the dental implant. For example, the cooling fluid may be applied intermittently with the steam, or the cooling fluid may be applied continuously while the steam is applied intermittently, according to various implementations.

Other ablation probes include apertures defined in the probe walls through which the fluid can flow to expand a balloon surrounding the radiating portion. Yet other ablation probes include a thermal indicator to indicate the temperature of the ablation probe to a user. The ablation systems include fluid circuits and associated mechanical controls for varying the contents and/or flow rate of the fluid provided to the radiating portion of the ablation probe.

  • Patent number: 9801756
    Abstract: A system includes a heat exchange catheter line assembly configured to convey working fluid circulating to and from at least one heat exchange element on an intravascular heat exchange catheter. The system also includes a heat exchange system that itself includes a processor and is configured for fluidly communicating with the heat exchange catheter line assembly to exchange heat with the working fluid. A near field communication (NFC) member associated with the heat exchange system and an NFC element associated with the heat exchange catheter line assembly are also included. The NFC member is configured to provide the processor with a signal representative of whether the NFC member detects the NFC element.

  • Patent number: 9717625
    Abstract: A catheter has a hollow conduit through which working fluid from a heat exchange system flows. The conduit in turn is configured to extend along a longitudinal central axis in a continuously varying non-constant azimuthal orientation so that it defines a non-round enclosed passageway through which blood can flow to exchange heat through a wall of the conduit with the working fluid flowing within the conduit.

  • Patent number: 9642741
    Abstract: Surgical cooling may be implemented by various systems, processes, and techniques. In certain implementations, a surgical cooling device includes a shaft, a cooling assembly, and a mechanical control system. The shaft includes a pair of axial cooling channels extending through its interior. The cooling assembly includes a pair of arms pivotally attached to the shaft and a foldable thermal exchanger coupled to the pair of arms and fluidly coupled to the pair of axial cooling channels. The mechanical control system is adapted to unfold the cooling assembly from a closed position to an open position to allow a coolant to flow through a first of the pair of axial cooling channels, through one or more thermal exchange channels, and out a second of the pair of cooling channels.

  • Patent number: 9622908
    Abstract: A device is provided for cooling intra nasally the brain of a patient, in particular of a patient suffering from cardiovascular emergency. The device comprises a pressurized gas container for containing a gas or a mixture of gases, and at least one cannula with a lumen, a proximal opening and at least one distal opening. The cannula is for introduction into the patient's nasopharynx. Upon operation, gas expands adiabatically upon exiting from the at least one cannula, thereby cools and provides a coolant effect on the nasopharynx and inside the nasal cavity.

  • Patent number: 9579150
    Abstract: A surgical ablation system features a source of ablation energy, a handle adapted to operably couple to the source of ablation energy, and an ablation probe adapted to operably couple to the handle. The handle includes a housing having a proximal end and a distal end, a hub included within the housing having a plenum defined therein, and a proximal feedline in fluid communication at a proximal end thereof with the plenum and joined at a distal end thereof to a first coupling member. The ablation probe includes a probe hypotube shaft having a proximal end and a distal end, a second coupling member disposed at a proximal end of the probe hypotube shaft adapted to operably couple with the first coupling member, a distal tip adapted to penetrate tissue. Ablation energy is deliverable by the ablation probe when the source of ablation energy is operably coupled to the handle and the handle is operably coupled to the ablation probe.

  • Patent number: 9375273
    Abstract: A microwave ablation system includes a generator operable to output energy and an ablation probe coupled to the generator that delivers the energy to a tissue region. The ablation system also includes a controller operable to control the generator and at least one sensor coupled to the ablation probe and the controller that detects an operating parameter of the ablation probe. The controller performs a system check by ramping up an energy output of the generator from a low energy level to a high energy level and monitors an output from the sensor at predetermined intervals of time during the system check to determine an abnormal state. The controller controls the generator to cease the energy output when the controller determines an abnormal state.
