摘要： A trocar having a trocar obturator and a trocar cannula. The trocar cannula has a cannula tube mounted in a cannula handle, wherein the cannula has an interior passage therethrough. The interior of the trocar cannula is visible through the trocar cannula. The trocar obturator is housed in the trocar cannula for insertion into a body cavity. When used in an endoscopic surgical procedure on a mammal, such that the trocar cannula is inserted into a body cavity and serves as a passageway to and from the body cavity, the interior of the trocar cannula is visible through the cannula so that the passage of instruments, sutures, staples, surgical tissue samples, etc., into and out of the mammalian body cavity through the cannula can be observed by a surgeon during an endoscopic procedure by observing the interior of the cannula at a point exterior to the cannula by looking through the cannula either directly or by using an endoscope.

摘要： An endoscopic imaging system for examining a patient's body cavity includes an endoscope having a distal end, a proximal end and a number of lumens therein. One or more distal gas ports are disposed at or adjacent the distal end of the endoscope and one or more proximal gas ports are disposed proximal to the distal gas ports. Insufflation gas is delivered to the distal gas ports and withdrawn from the proximal gas ports or vice versa such that a gas bubble is formed in the body cavity and travels with the distal tip of the endoscope.

摘要： A catheter for diagnosing and performing an interventional procedure on tissue has an elongated catheter shaft, and optical fibers, extending through the catheter shaft, for transmitting light to tissue located at a distal end of the catheter and conveying light back from the tissue for analysis by a spectroscopic diagnosis system to determine whether an interventional procedure should be performed on the tissue. An interventional device is located at the distal end of the catheter for engaging tissue diagnosed by the spectroscopic diagnosis system in order to perform the interventional procedure on the tissue. An assembly for imaging and performing an interventional procedure on tissue has an endo scope in combination with an endoscopically insertable catheter having an ultrasound imaging device for imaging a tissue structure located at a distal end of the endoscope so as to enable the depth of penetration of the tissue structure to be displayed, and an endoscopically insertable interventional device for engaging the tissue structure imaged by the ultrasound imaging device.
