Patent number: 8836521Abstract: 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.Type: GrantFiled: July 24, 2012Date of Patent: September 16, 2014Assignee: Lexion Medical LLCInventors: Duane Lloyd, Douglas E. Ott

Publication number: 20140180199Abstract: 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.Type: ApplicationFiled: December 20, 2012Publication date: June 26, 2014Inventors: Douglas E. Ott, Nathanial Tran
-
Publication number: 20140180198Abstract: 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.Type: ApplicationFiled: December 24, 2012Publication date: June 26, 2014Inventors: Douglas E.

Publication number: 20130303977Abstract: 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.Type: ApplicationFiled: July 31, 2012Publication date: November 14, 2013Inventors: Michael Spearman, John H. Burban, Douglas E. Ott, Majid Zia

Patent number: 8551050Abstract: Devices and methods for vacuum-assisted removal of surgically contaminated gas from an insufflated body cavity, the contaminants comprising smoke, aerosols, vapor, mist and the like generated during surgical procedures in order to clear the surgeon's vision of the surgical site and prevent exposure of the surgical staff to the gas. One embodiment of the present invention comprises a series of flow restriction devices to enable stepping down of the flow rate generated by an external vacuum. This reduced flow rate allows safe yet rapid removal of the toxic and vision-obstructing surgical byproducts from the patient's body cavity. The initial flow restriction device may comprise a perforated trocar sleeve in fluid communication with the vacuum source that allows retention of the surgical instrument within the trocar's inner lumen with concurrent smoke removal. The flow rate is infinitely variable, adjustable and selectable using a flow control adjuster comprising a smoothly varying orifice.Type: GrantFiled: June 10, 2011Date of Patent: October 8, 2013Assignee: Lexion Medical, LLCInventors: Douglas E. Ott, Nathaniel V. Tran

Publication number: 20130255670Abstract: In accordance with one embodiment of the present disclosure, a method for performing a surgical procedure may include atomizing at least a portion of a humidification liquid. The method may also include receiving a gas from a source. The method may further include generating a vortex flow of the received gas. The method may further include combining the vortex flow of the received gas with at least a portion of the atomized humidification liquid in order to humidify the received gas. The method may further include providing the humidified gas adjacent to or into a patient.Type: ApplicationFiled: April 1, 2013Publication date: October 3, 2013Applicant: Lexion Medical, LLCInventors: Douglas E.
