  • Patent number: 9028437
    Abstract: A method and apparatus for treating gas for delivery into a body cavity, body space or body surface of an animal. The apparatus comprises a housing defining a chamber having an entry port and an exit port. One or more agents are released into the gas stream that flows through the chamber so that the gas stream carries the agent to the animal. Also shown, for use with, or without, the chamber, is an agent chamber adapted to be coupled to at least one structure defining at least one fluid flow path extending at least a portion of the distance between an insufflation device and the body cavity, body space or body surface.

  • Patent number: 9017280
    Abstract: An apparatus for conditioning gas for use in a medical procedure, the gas being received into the apparatus from a gas source. The apparatus comprises a housing defining a chamber having an entry port and an exit port. The housing contains at least a humidification means comprising a container for liquid, such as at least one liquid retaining layer that is disposed within the chamber in the path of travel of the gas for humidifying the gas as it passes through the chamber. A humidity sensor may be disposed within the chamber that senses the humidity of the gas exiting the chamber. A monitoring circuit is connected to the humidity sensor that detects when the chamber requires a recharge of liquid based on the humidity of the gas in the chamber, and generates a recharge signal indicative thereof a charging port on the housing provides access into the chamber to recharge the chamber with water. Alternatively, a backup container of liquid is provided to continuously supply liquid to the humidification means.

  • Patent number: 8945040
    Abstract: An apparatus and method for on-the-go humidifying an insufflation gas through water vapor transfer from a liquid to the insufflation gas through a barrier separating the gas from the liquid to enable the gas in a normally trauma inducing state to be brought to a conditioned state. If the gas is at an improper insufflation temperature the temperature of the gas can be brought to the proper insufflation temperature at the same time the gas is humidified through heat transfer through the barrier.

  • Patent number: 8932248
    Abstract: A gas conditioning trocar having a chamber for heating and hydrating an unconditioned insufflation gas prior to injecting a conditioned insufflation gas into a body cavity during a medical procedure and a port through which surgical instruments can pass into a body cavity without inhibiting the flow of insufflation gas during the medical procedure.

  • Patent number: 8836521
    Abstract: One aspect of the invention is an apparatus including an alarm for alerting an operator to recharge a humidifier, wherein such alarm is generated other than through the use of a humidity sensor. In one embodiment the total work performed during heating and hydrating an insufflation gas is measured and an alarm generated when the total work performed exceeds a particular threshold. In another embodiment, a flow meter is used to measure the total flow of insufflation gas so that when the total flow of insufflation gas reaches a predetermined level an alarm is activated.

  • Patent number: 8715264
    Abstract: A charged hydration device and a method of filling the hydration device so the charged hydration that can be mounted to a medical apparatus that provides insufflation fluid to a body cavity either immediately prior to the medical procedure or during a medical procedure with the charged hydration device including an inlet and outlet for an inline connection with the medical apparatus so that an insufflation gas delivered through the charged hydration device is hydrated to prevent tissue damage to a person receiving the insufflation gas.

  • Patent number: 8696563
    Abstract: The present invention comprises devices and methods that, in certain embodiments, provide a lighted cup, ring or cap that comprises a customizable size and fit, for use in hysterectomy procedures, whereby the ring or cup engages the vaginal fornix and is covered by the vaginal cervical tissue. The lighting allows the surgeon to visualize the location of the lighted cup, ring or cap, thereby quickly and accurately identifying the incision site while providing protection of the associated vasculature and the ureters.

  • Patent number: 8608715
    Abstract: One aspect of the invention is a method to vent gas from a body cavity during an endoscopic procedure. A body cavity is in fluid communication with an exhaust gas inlet of a vacuum break device. The vacuum break device has a chamber in fluid communication with both the inlet and an outlet. The chamber may comprise one or more openings in fluid communication with the atmosphere. A conduit in fluid communication with the exhaust gas outlet may be connected directly or indirectly to a suction source. The suction source may be activated.

  • Patent number: 8551049
    Abstract: Devices and methods for vacuum-assisted removal of surgically contaminated gas from an insufflated body cavity, the contaminants comprising smoke, aerosols, vapor, mist and the like generated during surgical procedures in order to clear the surgeon's vision of the surgical site and prevent exposure of the surgical staff to the gas. One embodiment of the present invention comprises a series of flow restriction devices to enable stepping down of the flow rate generated by an external vacuum. This reduced flow rate allows safe yet rapid removal of the toxic and vision-obstructing surgical byproducts from the patient's body cavity. The initial flow restriction device may comprise a perforated trocar sleeve in fluid communication with the vacuum source that allows retention of the surgical instrument within the trocar sleeve's inner lumen with concurrent smoke removal.
