Publication number: 20110160535Abstract: Disclosed is a disposable access port for use in endoscopic procedures, including laparoscopic procedures. The access port includes a cannula with an embedded camera in communication with an external control box. In operation, a trocar is combined with the access port to facilitate insertion of the access port into an anatomical site. Prior to insertion, the camera is pushed inside the cannula, where it remains during insertion. The trocar is removed after the access port has been inserted to allow surgical instruments to access the anatomical site. During removal of the trocar, a portion of the trocar urges the camera out of the cannula, thereby allowing visualization of the anatomical site. The camera can be fixedly or adjustably mounted on the port. A camera may also be mounted on the trocar. The trocar may include irrigation and suction channels to facilitate a clear view of the anatomical site.Type: ApplicationFiled: March 8, 2011Publication date: June 30, 2011Applicant: Avantis Medical Systems, Inc.Inventors: Lex Bayer, Jack Higgins

Publication number: 20080021274Abstract: An endoscopic system having an endoscope carrying an endoscopic medical device that can be an auxiliary rear-ward facing camera or medical tool for cutting, ablation, cutting, suturing, retracting, manipulating, suction, or irrigation. A locking assembly allows the user of the system to lock the rotational orientation of a distal portion of endoscopic medical device within a distal end of the endoscope. The locking assembly has a locking device attached to the distal portion of the endoscopic medical device and a cap that is permanently or removably attached to the distal end of the endoscope. When desired, the user of the system engages the locking device and the cap together to prevent rotation. The locking device can include one more flexible members that can contract when pushed through a working channel of the endoscope and expand to engage mating features on the cap. Magnets can also be used to prevent rotation.Type: ApplicationFiled: May 21, 2007Publication date: January 24, 2008Applicant: Avantis Medical Systems, Inc.Inventors: Lex Bayer, Diel Mark

Publication number: 20070293720Abstract: An endoscope assembly includes a first imaging device and a second imaging device, and the first and second imaging devices are positioned to provide different views of the same area at the same time. A method of viewing an area inside a cavity includes the step of using first and second imaging devices to view the same area inside a cavity at the same time.Type: ApplicationFiled: July 26, 2007Publication date: December 20, 2007Applicant: Avantis Medical Systems, Inc.Inventor: Lex Bayer

Publication number: 20070279486Abstract: A method for reducing an effect of a video artifact includes adjusting a phase of a second imaging device's video clock signal so that a phase of the second imaging device's video synchronization signal matches a phase of a first imaging device's video synchronization signal. An endoscopic system includes a first imaging device, a second imaging device, a light source, and a controller that reduces an artifact in an image produced by the first imaging device. In some embodiments, the first imaging device faces the light source.Type: ApplicationFiled: May 21, 2007Publication date: December 6, 2007Applicant: Avantis Medical Systems, Inc.Inventors: Lex Bayer, Okas Robert

Publication number: 20070270642Abstract: A method for displaying images includes adjusting at least one characteristic of an image from a first imaging device of an endoscope to match at least one corresponding characteristic of an image from a second imaging device of the endoscope. The at least one characteristic may be one or more of color, contrast and brightness. An endoscopic system includes an endoscope including a first imaging device and a second imaging device, and a display device that displays an image from the first imaging device of the endoscope and an image from the second imaging device of the endoscope, wherein the images are sized so that an object, when placed at the same distance from the imaging devices, appears to have about the same size in the images.Type: ApplicationFiled: May 21, 2007Publication date: November 22, 2007Applicant: Avantis Medical Systems, Inc.Inventors: Lex Bayer, Michael Stewart

Publication number: 20070015989Abstract: An endoscope is communicatively coupled to electronics that receive images of tissue from the endoscope and determine a correlation between the received images and images of normal and abnormal tissues in a database. Based on the determined correlation, an operator of the endoscope is notified of the correlation and the electronics can cause the endoscope to act accordingly (e.g., biopsy abnormal tissue).Type: ApplicationFiled: July 1, 2005Publication date: January 18, 2007Applicant: AVANTIS MEDICAL SYSTEMS, INC.Inventors: Rupesh Desai, Fred Seddiqui, Jack Higgins, Alex Niel
