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.

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 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.

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.

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: In accordance with one embodiment of the present disclosure, a surgical method may include making a first incision in a patient. The surgical method may also include receiving a gas from a source and humidifying and warming the gas received from the source. The surgical method may further include delivering the humidified and warmed gas into the first incision. The surgical method may further include separating one or more blood vessel branches from a blood vessel using at least one surgical instrument inserted through a second incision in the patient. The surgical method may further include removing a blood vessel segment from the patient through a third incision in the patient, wherein the blood vessel segment was in contact with the humidified and warmed gas delivered into the first incision prior to the removal.

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: High resolution full disclosure ECG data is transferred from a body sensor device to a handheld device via a wireless protocol. The handheld device transfers the full disclosure ECG data via a cellular network to a data center for analysis. A monitoring center communicating with the data center facilitates technician and physician review and interactions.

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.
