Publication number: 20120310147Abstract: Methods and systems for accessing an operating cavity when performing endoscopic surgery comprising. The systems and methods include at least one obturator-free cannula unit and a trocar assembly. The trocar assembly includes a single dedicated functional obturator independent of the cannula unit and an endoscopic cannula. The invention also provides a system and methods for providing continuous flow of carbon dioxide during a laparoscopic procedure.Type: ApplicationFiled: December 5, 2011Publication date: December 6, 2012Applicant: MINIMALLY INVASIVE DEVICES, LLCInventors: WAYNE L. POLL, GREGORY DRACH

Publication number: 20120197084Abstract: A view optimizing assembly, method and kit for use in combination with a laparoscope having a lens located on the shaft tip of the laparoscope, and a source of insufflation CO2. The invention includes a multi-lumen sheath assembly, a deflector assembly in fluid communication with the lumens of the sheath assembly, wherein the flow of CO2 through the lumens forms a vortex when coming into contact with the deflector assembly, thereby preventing fogging of the laparoscope lens.Type: ApplicationFiled: August 4, 2011Publication date: August 2, 2012Applicant: MINIMALLY INVASIVE DEVICES, LLCInventors: Gregory P. Drach, Wayne L. Poll

Publication number: 20120184897Abstract: Air management control systems and methods maintain and manage an intra-abdominal gas environment during laparoscopic surgery. The systems and methods locate a plurality of in vivo sensors to monitor different environmental conditions within the operative space insufflated with pressurized CO2, e.g., CO2 insufflation airflow velocity, CO2 pressure, aspiration airflow velocity, and at least one of humidity level, temperature, density of smoke/particulates, odors, and sound within the operative space. The systems and methods couple the plurality of in vivo sensors to a master controller. The master controller implements pre-programmed rules to generate control commands that govern the delivery of pressurized CO2 and aspiration pressure into and out of the operative space in response, at least in part, to the different environmental conditions monitored by the in vivo sensors.Type: ApplicationFiled: July 19, 2011Publication date: July 19, 2012Applicant: MINIMALLY INVASIVE DEVICES, LLCInventor: Wayne L. Poll

Publication number: 20120165610Abstract: Systems and methods condition air for passage across a laparoscopic lens to prevent fogging, deflect debris, and maintain visualization of an operating cavity. The systems and methods provide an access device sized and configured to provide communication with an insufflated CO2 environment maintained by operation of an insufflations circuit. The access device is coupled to an air conditioning set, which interacts with an air conditioning driver to condition air from the insufflated environment for continuous passage across the laparoscopic lens, to thereby maintain visualization by the laparoscopic lens of the operating cavity, independent of operation of the insufflator circuit.Type: ApplicationFiled: June 22, 2011Publication date: June 28, 2012Applicant: MINIMALLY INVASIVE DEVICES, LLCInventors: Wayne L. Poll, Caroline M. Crisafulli, Gregory P. Drach

Publication number: 20120022331Abstract: Systems and methods couple a self contained air processing or conveying component to a sheath that is sized and configured to receive a laparoscope including a laparoscopic lens providing visualization of an operating cavity. The air processing or conveying component comprises an air flow path having an inlet sized and configured for communication with a source of CO2 and an outlet. The air processing or conveying component includes a driven air moving component in communication with the air flow path sized and configured to continuously convey CO2 from the source through the air flow path to the outlet. The sheath coupled to the air processing or conveying component can include a lumen communicating with the outlet of the air processing or conveying mechanism for passing CO2 continuously conveyed by the driven air moving component across the laparoscopic lens to maintain visualization of the operating cavity.Type: ApplicationFiled: January 11, 2011Publication date: January 26, 2012Applicant: MINIMALLY INVASIVE DEVICES, LLCInventors: Wayne L. Poll, Caroline M. Crisafulli, Gregory P. Drach

Patent number: 7771435Abstract: A surgical instrument for fragmenting and extracting stones includes an outer sheath having a proximal end and a distal end and an inner core longitudinally extending through the core and longitudinally movable relative to the core. The outer sheath has a basket sized for entrapping the stones and located near the distal end of the outer sheath. The distal end of the inner core is longitudinally moveable from a retracted position within the basket to an extended position past the distal end of the outer sheath. The distal end of the inner core is also adapted to engage and fragment the stones. Longitudinal movement of the inner core relative to the outer sheath transforms the basket from an expanded condition to a collapsed condition to entrap stones within the basket and provide a small profile for insertion and withdrawal.Type: GrantFiled: April 24, 2008Date of Patent: August 10, 2010Assignee: Minimally Invasive Devices, LLCInventor: Wayne L. Poll

Publication number: 20100168520Abstract: The present application discloses several devices for maintaining visualization with a surgical scope. The embodiments of the device are adapted to shield, defog or clean the lens of the surgical scope while the surgical scope is being used to perform a surgical procedure within a patient's body. In some embodiments, the view optimizer is provided in multiple parts enabling separation of one or more operator control features from engagement with the surgical scope. In some embodiments, the view optimizer features stabilization means for securement and positioning with the surgical scope.Type: ApplicationFiled: December 10, 2009Publication date: July 1, 2010Applicant: MINIMALLY INVASIVE DEVICES, LLCInventors: Wayne L. Poll, Matthew J. Huddleston, Caroline M. Crisafulli, Adam Landis, Gregory Drach

Publication number: 20080319266Abstract: The present application discloses several embodiments of a devices for maintaining visualization with a surgical scope. The embodiments of the device are adapted to shield, defog or clean the lens of the surgical scope while the surgical scope is being used to perform a surgical procedure within a patient's body. In one embodiment, a view optimizer is provided that is adapted to deliver at least one fluid to the objective lens of the laparoscope to clean and/or defog the objective lens of the laparoscope without the need to remove the laparoscope from the surgical field. In additional embodiments, a view optimizer is provided that is adapted to create leakage or venting of gas from the body cavity so as to ensure continuous gas flow from an insufflator.Type: ApplicationFiled: June 19, 2007Publication date: December 25, 2008Applicant: MINIMALLY INVASIVE DEVICES, LLCInventors: Wayne Lyle Poll, Matthew J. Huddleston, William J. Post, Thomas J. Ward, Caroline M. Crisafulli, Adam Landis
