Patent number: 8551036Abstract: An aerosol generator is positioned adjacent to a patient as an attachment to a trocar. The trocar has an entry port for insufflation gas. Aerosol generated by a vibrating element is entrained in the insufflation gas and the mixture is delivered through the trocar. The aerosol may contain a medicament. The trocar may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolized medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolized medicament to the pneumoperitoneum regions. The surgeon can temporarily remove the camera from the trocar port to facilitate insertion and positioning of the aerosolizing unit.Type: GrantFiled: February 9, 2012Date of Patent: October 8, 2013Assignee: Aerosurgical LimitedInventors: Patrick Joseph Power, Conor Paul Duffy

Publication number: 20120253265Abstract: Non-thermal plasma is a partly ionized gas, which can be generated by a high-voltage electric field at a low pressure. Disclosed herein are apparatuses and methods for treating an enteric disease in vivo using non-thermal plasma. The disclosed apparatuses have a first conduit comprising a lumen and a tip; a first electrode disposed within the lumen of the first conduit; a second electrode comprised of a metal conduit disposed within the first conduit; an insulator disposed within the lumen of the first conduit, the insulator configured to electrically insulate the first electrode from the second electrode; and a gas channel disposed between the outer surface of the metal conduit and the inner surface of the first conduit, the gas channel being capable of feeding a gas from a gas source to the tip, wherein when the potential is applied, the gas is ionized to produce the non-thermal plasma.Type: ApplicationFiled: March 16, 2010Publication date: October 4, 2012Applicant: Drexel UniversityInventors: Gregory Fridman, Danil V.

Publication number: 20120253166Abstract: Provided is a canal type mini-apparatus insertable in an ear for diagnosing a disease. The canal type mini-apparatus includes a canal body and a protrusion body. The canal body is insertable in an ear and includes a bio-data detection unit at an end thereof The bio-data detection unit is configured to detect biological data from an inside of the ear for diagnosing a disease. The protrusion body is disposed at the other end of the canal body and including a data transceiving unit. The data transceiving unit is configured to control the bio-data detection unit and transmit/receive a signal to/from an analyzing device. When the canal type mini-apparatus is inserted in the ear, at least a portion of the protrusion body protrudes outward from the ear.Type: ApplicationFiled: January 23, 2012Publication date: October 4, 2012Applicant: Electronics and Telecommunications Research InstituteInventors: Chang-Geun AHN, Sooyeul Lee

Patent number: 8269638Abstract: 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: October 16, 2008Date of Patent: September 18, 2012Assignee: Lexion Medical LLCInventors: Duane Lloyd, Douglas E.
