Abstract: A medical gas condition system for supplying a liquid hydration fluid to a hydrator before or during an ongoing medical procedure by coupling the flow of liquid hydration fluid into the hydrator to either the absence of flow of medical insufflation gas into the hydrator or to a condition where the liquid hydration fluid can be absorbed by a hydrator without being forced through the hydrator in liquid form.

Abstract: According to one embodiment, a method includes positioning a trocar having a pressure sensor in or on the trocar into a patient cavity such that distension of the patient cavity causes an altitude of the pressure sensor to increase. The method also includes distending the patient cavity by supplying an insufflation gas to the patient cavity, thereby increasing an altitude of the pressure sensor from a first altitude to a second altitude. The method also includes determining a change in pressure at the pressure sensor resulting from increasing the altitude of the pressure sensor from the first altitude to the second altitude and controlling the supply of insufflation gas to the patient cavity in response to the determined change in pressure resulting from increasing the altitude of the pressure sensor from the first altitude to the second altitude.

Abstract: In accordance with one embodiment of the present disclosure, a surgical method may include making an incision in a patient. The method may also include opening the incision in order to create an open surgical site in the patient. The method may further include receiving a gas from a source. The method may further include humidifying and warming the gas received from the source. The method may further include successively reflecting the humidified and warmed gas off a plurality of non-porous surfaces within a non-porous gas delivery mechanism to create a flow. The method may further include delivering the flow of the humidified and warmed gas adjacent to or into the open surgical site.

Abstract: A trocar sleeve that isolates the surgical device or movement thereof to inhibit or prevent an established non-jet streaming condition from becoming a jet streaming condition and a method of inhibiting or preventing a jet streaming condition from occurring due to instrument obstruction.

Abstract: A fail-safe insufflation device having a thermal cutoff for interrupting power to an electrical heater to prevent overheating of insufflation gas wherein the thermal cutoff operates independent of a temperature control system to provide electrical shutdown of an electrical heater in response to a hostile temperature condition of the insufflation gas or a hostile temperature condition proximate the electrical heater.

Abstract: A cannula adapter for converting a trocar insufflator into a two-phase or two-mode insufflation system. In the needle insufflation mode the insufflation gas flows through a trocar cannula, a cannula adapter and an insufflation needle before entering a body cavity and in the trocar insufflation mode gas flows directly into the body cavity from the trocar cannula. The cannula adapter although sealingly attachable to the trocar cannula during the needle insufflation mode is removable therefrom for a seamless transfer between the needle insufflation mode and the trocar insufflation mode.

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.

Abstract: An insufflation apparatus and/or insufflation kit for use during a medical procedure including a fluid stabilizer wherein the insufflation apparatus can be used in different modes with a mode change between needle insufflation or cannula insufflation accomplished without having to use a different fluid stabilizer or a different trocar wherein the trocar may be a gas conditioning trocar having a chamber for on-the-go heating and hydrating an unconditioned insufflation gas prior to injecting a conditioned insufflation gas into a body cavity.

Abstract: An apparatus and method for clearing of a surgical site during the performance of a medical procedure where a single phase wash fluid, which has been conditioned, is directed at the surgical site to inhibit or prevent harm to the body tissue as unwanted debris is blown away from the surgical site thereby permitting a surgeon to safely perform a medical procedure without the presence of unwanted liquids or unwanted debris at the surgical site.

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.

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.

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.
