Patent number: 7927272Abstract: 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: GrantFiled: August 6, 2007Date of Patent: April 19, 2011Assignee: Avantis Medical Systems, Inc.Inventors: Lex Bayer, Jack Higgins

Publication number: 20030176766Abstract: An apparatus for guiding an instrument inserted through an endoscope's instrument channel is provided. The apparatus can attach to an endoscope to guide the position of the end of the instrument, such as by constraining the instrument to bend in a predetermined manner, or otherwise guide the distal end of the instrument extending from the distal end of the instrument channel. The apparatus can be used to assist in positioning the instrument to peform useful work on tissue adjacent the perimeter of the endoscope. The apparatus can also be used to provide cooperation between instruments inserted either through or alongside the endoscope.Type: ApplicationFiled: March 15, 2002Publication date: September 18, 2003Inventors: Gary L.

Publication number: 20030145865Abstract: The invention provides devices and methods for performing less-invasive surgical procedures within an organ or vessel. In an exemplary embodiment, the invention provides a method of closed-chest surgical intervention within an internal cavity of a patient's heart or great vessel. According to the method, the patient's heart is arrested and cardiopulmonary bypass is established. A scope extending through a percutaneous intercostal penetration in the patient's chest is used to view an internal portion of the patient's chest. An internal penetration is formed in a wall of the heart or great vessel using cutting means introduced through a percutaneous penetration in an intercostal space in the patient's chest. An interventional tool is then introduced, usually through a cannula positioned in a percutaneous intercostal penetration.Type: ApplicationFiled: July 10, 2001Publication date: August 7, 2003Inventors: Wesley D. Sterman, Michi E. Garrison, Hanson S. Gifford, John H. Stevens, William S. Peters

Publication number: 20030130561Abstract: The holding device of the endoscope allows suspension of the tissue while it is held and fixed securely. Use of holding device with large distal ends will not damage tissue and allows holding and suspension of a large area. A needle pierces at least the proper muscularis, thereby forming a large protrusion including the proper muscularis of the stomach and the esophagus as artificial valve to prevent reflux effectively. The holding device, formed extending out of the distal end of the endoscope, can touch the tissue easily under observation of the endoscope. Treatment is simple, and takes a shorter time.Type: ApplicationFiled: January 3, 2003Publication date: July 10, 2003Inventors: Takayuki Suzuki, Pankaj P. Pasricha

Publication number: 20030040657Abstract: A treatment instrument passage channel through which a treatment instrument can be passed lies through an elongated insertion unit that is inserted into a body cavity or the like. The distal opening of the treatment instrument passage channel opens onto the distal part of the insertion unit. A treatment instrument swing stand having a hole, through which the distal part of a treatment instrument led out of the distal opening is passed, bored therein is disposed near the distal opening so that the treatment instrument swing stand can swing freely. The treatment instrument swing stand is manipulated by proximally pulling angling wires. Thus, the distal part of the treatment instrument is swung from a position near the center of a field of view in both the rightward and leftward directions of an endoscope. Thus, the mucosa of a lesion can be resected easily while being caught in the field of view.Type: ApplicationFiled: July 22, 2002Publication date: February 27, 2003Applicant: OLYMPUS OPTICAL CO., LTD.Inventors: Koji Yamaya, Koji Nakamoto, Hisao Yabe
