The apparatus also includes an obturator assembly, the obturator assembly configured to be inserted through a cannula so as to define an interstitial space between the cannula and the obturator assembly. The interstitial space is in fluid communication with the cannula connection so as to convey the insufflation fluid. The obturator assembly includes an obturator shaft having a hollow interior and a tip member at a distal end of the obturator shaft. The tip member is configured to penetrate and/or dissect through tissue. The tip member has an outer surface that defines a channel, the channel being in fluid communication with the interstitial space to as to convey the insufflation fluid from a proximal end of the tip member to a distal end of the tip member.Type: ApplicationFiled: May 30, 2013Publication date: December 12, 2013Inventors: Christopher Kelly Evans, Gregory Fischvogt

Publication number: 20130324803Abstract: A laparoscopic instrument for forming an incision in a body cavity, insufflating the body cavity with gas, and suturing the incision at the completion of the surgery includes a set of jaws at the distal end of the Veress needle or cannula. The jaws are pivoted to one another for motion between an open position or a closed position in which they may be used to grasp a suture in the body cavity for removal from the cavity for knotting. A push mechanism at the proximal end of the instrument moves the jaws between their open and closed position on successive actuations of a pushbutton and retains them in that state until the next push. An illumination source is provided for the distal end of the instrument to provide illumination through the walls of the body cavity so that the surgeon can determine the degree of penetration of the instrument into the body cavity and can identify any major arteries which should be avoided in the formation of other laparoscopic openings.Type: ApplicationFiled: August 13, 2013Publication date: December 5, 2013Inventor: Reza S. Mohajer

Publication number: 20130324914Abstract: A system for insufflating a body cavity comprising a swallowable capsule comprising a chamber (11) containing a fluid capable to generate biocompatible gas or vapour by phase transition or chemical reaction, the chamber (11) being formed with at least one orifice (7) for placing it in communication with the outside. The orifice (7) is blocked by a shutter (4, 6; 26) made of magnetic material and there are provided elastic means (8) able to generate an elastic force sufficient to keep said shutter sealingly engaged in the orifice. The system further comprises magnetic actuating means (12; 34) external to the body cavity for generating a magnetic force having strength sufficient to overcome the elastic force of the elastic means disengaging the shutter from the orifice.Type: ApplicationFiled: August 26, 2011Publication date: December 5, 2013Applicant: VANDERBILT UNIVERSITYInventors: Pietro Valdastri, Gastone Ciuti, Arianna Menciassi, Paolo Dario, Robert J.

Publication number: 20130303848Abstract: A surgical access system comprises a trocar, an insufflating optical obturator slidably insertable into the trocar, and a laparoscope slidably insertable into the obturator. A distal end of the obturator comprises a tip, at least a portion of which comprises a wall with a generally uniform thickness comprising a transparent material. At least one vent hole disposed at the obturator tip is fluidly connected to a gas flow channel defined by an interior surface of the obturator and the laparoscope, which is fluidly connected to an insufflation gas inlet disposed at a proximal end of the trocar. Improved optical characteristics of the trocar system permit precise and accurate visual placement thereof into a body cavity. Accordingly the access system is suitable as a first entry surgical access system. Embodiments of the trocar access are also useful for drug delivery, and/or for fluid and/or tissue aspiration.Type: ApplicationFiled: July 12, 2013Publication date: November 14, 2013Applicant: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz Strokosz, Scott V.

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

Publication number: 20130289473Abstract: A medical conduit includes a first conduit, a second conduit and a third conduit. The first conduit is bigger than the third conduit in length and built within the third conduit; one end of the first conduit penetrates a bore at one end of the third conduit, while the other end of the first conduit penetrates a through-hole on the side wall of the other end of the third conduit and, together with the other end of the third conduit, forms a Y shape; the side wall at the other end of the first conduit is provided with a number of through-holes for guiding liquid or gas; one end of the second conduit is embedded at the bore at one end of the third conduit. The medical conduit can perform guidance and location in a human body and separately conduct injection and exhaustion to provide accurate measuring data for doctors.Type: ApplicationFiled: August 3, 2012Publication date: October 31, 2013Inventor: Tak Suen Sze

Publication number: 20130274652Abstract: A warming gas flows through a jacket to heat an insufflation gas flowing in a separate tube, thereby reducing cost and disposable waste. The heated warming gas may be filtered to sterilize or maintain sterility and released to atmosphere after heating the flowing insufflation gas. Alternatively the warming gas may be reheated and recirculated through the jacket, with an additional tube being used within the jacket so that the warming gas flows in both directions lengthwise. As an alternative to separate tubes, a single, multi-lumen tube may be used. The insufflation gas may be CO2 and the warming gas may be room air. The heating element and sensors may be separate from the disposable unit of a heated insufflation set, and need not be re-sterilized prior to or after use in surgery. The heat is constantly maintained, thereby eliminating “cold spots” caused by the natural cycling of the resistance heaters.Type: ApplicationFiled: May 21, 2013Publication date: October 17, 2013Inventor: John Temple
