A surgical access port or trocar is provided. The trocar has a trocar seal housing and a trocar cannula with an optical obturator insertable through the trocar seal housing and the trocar cannula. The trocar is configured to access a body cavity, to maintain positive pressure and to prevent loss of surgical insufflation gas used in laparoscopic procedures. The trocar seal housing can be releasably attached to the trocar cannula. The trocar seal housing may also have a shield and/or alignment channel that provide protection or assist in operation of instrument and zero seals housed in the trocar seal housing.

An access device for a minimally invasive procedure can include a port body defining an instrument channel for a medical instrument, a radial extension extending at least partially outward from the body in a radial direction. The radial extension can extend from a distal end of the port body. The radial extension can define an imaging device cavity defined therein spaced from the port body and opening distally from the radial extension. The imaging device cavity can be configured to receive an imaging device therein for providing images within a field of view that is at least partially distal of the port body.

Disclosed is an endoscope for measuring intra-organ pressure (e.g., intragastric pressure), and more particularly an endoscope for measuring intra-organ pressure (e.g., intragastric pressure) and visualizing the response of an adjacent sphincter (e.g., lower esophageal sphincter) to changes in the intra-organ pressure.

An electrosurgical device is adapted for use through a port and within a body cavity. The device includes a gas supply supplying gas to a distal tip and a valve to regular such supply, and an electric supply for supplying electricity to the distal tip. A pressure relief system is provided to regulate an outflow of gas from within the body cavity to prevent exceeding a predetermined pressure. The inflow of the gas through the valve and outflow of gas through the pressure relief system may occur simultaneously.

The present disclosure relates to a bandage wherein the bandage comprise of a first layer of protective covering, wherein the first layer is removable; a second layer of covering, wherein the second layer of covering is made of a cloth material; a third layer of covering, wherein the third layer is the top most layer of the bandage and together with the second layer forms a support pad; an injection, wherein the injection is present on the second layer of covering; a cylinder, wherein the cylinder is present in the support pad, wherein the bandage is used for delivering a medication to a localized area on a patient's body. The bandage is further used for delivering localized, painless ozone gas treatment to a patient suffering from infectious disease. The bandage is easy to carry and comes in various shapes and sizes.

The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.

Detection of moisture conditions in a conduit, particularly a gases supply system conduit for supplying respiratory or surgical gases, using an electrical property of the conduit.

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.

Systems, methods and kits for treating hemorrhages within cavities are provided. The methods utilize the application of a rapid spike of pressure to the closed cavity, followed by a steady state pressure or pressures.

An improved system and method of controlling the operation of a respiratory or surgical humidifier system that can provide humidified gases of substantially constant humidity in dependence upon only one monitored variable, being signals received from a temperature sensor. A power controller can be configured to control a level of power supplied to a heater plate in dependence upon heater plate temperature and a humidity profile so as to drive an operating point of the humidifier towards the humidity profile. The rate of change of a heater plate temperature setpoint can be variably controlled in dependence upon a heater plate temperature setpoint and heater plate temperature.
