Filed:

Oct 7, 2004

Appl. No.:

10/960188

Inventors:

Douglas E. Ott - Macon GA, US
Patrick R. Spearman - The Woodlands TX, US
Robert I. Gray - Macon GA, US
Duane E. Lloyd - Big Lake MN, US

Assignee:

Lexion Medical, LLC - St. Paul MN

International Classification:

A61M 37/00

US Classification:

604 23

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.

Appl. No.:

11/485864

Inventors:

Douglas E. Ott - Macon GA, US
Robert I. Gray - Macon GA, US
Duane Lloyd - Glasgow MT, US

Assignee:

Lexion Medical LLC - St. Paul MN

International Classification:

A61M 37/00

US Classification:

604 24, 604 26, 604113, 12820417

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.

Appl. No.:

12/288133

Inventors:

Duane Lloyd - Glasgow MT, US
Douglas E. Ott - Macon GA, US

Assignee:

Lexion Medical LLC - St. Paul MN

International Classification:

G08B 17/10

A61M 31/00

US Classification:

340603, 340635, 604 23, 604 26, 604 65

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:

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.
