A hybrid apparatus for delivery of fluid in connection with endoscopic irrigation and lens cleaning including a connector which is adaptable to a flexible or rigid container, a connector arranged at the end thereof and connected via a tubing supply to a fluid, air and or gas source and to an endoscope during a procedure.

A device for inhibiting condensation distortion on an optical element of a medical instrument configured for insertion into a body cavity is provided. The device may include a housing; a cavity within the housing, the cavity being sized to removably retain at least a portion of the medical instrument therein, wherein the portion includes the optical element; a plasma activation zone within the cavity and arranged such that when the at least a portion of the medical instrument is retained within the cavity, the optical element is located within the plasma activation zone; a plasma generator configured to be activated to cause formation of a plasma cloud in the plasma activation zone in a vicinity of the optical element; and a controller configured to activate the plasma generator for a time period sufficient to cause the optical element to become hydrophilic prior to insertion into the body cavity.

A medical device and associated methods are disclosed. In one example, the medical device includes an endoscope lens. In one example, the medical device includes a regular periodic physical structure. Examples of regular periodic physical structure may be formed from a bulk material of a component such as a lens, or a regular periodic physical structure may be formed as a coating.

A device for inhibiting condensation distortion on an optical element is provided. The device may include a housing; a chamber within the housing; electrical circuitry in the housing; a plasma activation region configured to retain the optical element in a manner exposing an optical surface to the plasma activation region, wherein the electrical circuitry is configured to form an electrical connection with a first electrode located on the first side of the dielectric barrier; a second electrode located on a second side of the dielectric barrier, opposite the plasma activation region; and at least one processor configured to: control electricity flow through the circuitry to cause an electric field associated with a voltage drop between the first electrode and a second electrode to generate plasma within the plasma-activation region; and maintain the generated plasma for a time period sufficient to cause the optical surface to become hydrophilic.

A Laparoscopic Visualization System comprising a sterile, self-contained, disposable apparatus used in medical procedures for heating and applying an anti-fog solution to the distal end of laparoscopes or surgical devices is presented. It additionally serves as an endoscopic lens protector and cleaner. An efficient heating and narrow range temperature control mechanism is used in combination with an anti-fog solution to provide clear visualization through a distal lens of the surgical device inserted into the system. The configuration prevents the anti-fog solution from spilling out of the system and is designed to also be used as a holder for the surgical scope, protecting the distal lens from impact with a shock absorbent outer shell, prior to, during, and after a medical procedure.

A method for defogging an optical component of an endoscope includes operating an illuminator in an imaging mode in which the illuminator generates illumination light for endoscopic imaging of a target, wherein at least a portion of the illumination light is generated by a light source that generates light having a first waveband at an imaging intensity level; and changing the operating mode of the illuminator from the imaging mode to a defogging mode in which an intensity level of the light having the first waveband is increased from the imaging intensity level to a defogging intensity level to warm and defog the optical component of the endoscope.

A device and method for cleaning or defogging a surgical scope during minimally-invasive surgery, including a casing which houses a sponge and a heating element configured to be accessible to the surgical scope and the casing is configured to removably attach to a trocar during a surgical procedure.
