Abstract
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 Insufflation gas is delivered to the distal gas ports and withdrawn from the proximal gas ports or vice versa such that a gas bubble is formed in the body cavity and travels with the distal tip of the endoscope.
Claims18
An endoscope comprising:
- an elongate member having a proximal end and a distal end and defining a plurality of lumens;
- one or more first ports disposed at or adjacent to a distal end of the endoscope and connected to a source of gas or liquid;
- one or more second ports formed in the elongate member at an axial position proximal of the one or more distal ports;
- a controller including a processor configured to deliver gas or liquid to the one or more first ports while applying suction to the one or more second ports;
- and
- a manifold, wherein the manifold is configured to reverse the delivery of gas or liquid and the application of suction so that the one or more first ports is applying suction while the one of more second ports is delivering gas or liquid.
An endoscope, comprising:
- an elongate member;
- a cap provided at a distal end of the elongate member, the cap defining a first set of ports, wherein the cap includes an imaging assembly, and wherein a proximalmost end of the imaging assembly is distal to the distal end of the elongate member;
- a second set of ports disposed proximal to the first set of ports;
- a controller configured to deliver gas or liquid to one of the first and second set of ports while applying suction to the other of the first and second set of ports and regulate pressure at the distal end of the elongate member;
- and
- a manifold, wherein the manifold is configured to reverse the delivery of gas or liquid and the application of suction so that the one or more first ports is applying suction while the one of more second ports is delivering gas or liquid.
An endoscope, comprising:
- an elongate member;
- a first set of ports in communication with one or more lumens extending from a proximal end of the elongate member;
- a second set of ports disposed proximal to the first set of ports, wherein one of the first and second set of ports is configured to deliver gas as a vacuum is applied to the other of the first and second set of ports;
- a pressure sensor at a distal end of the elongate member;
- and
- a manifold, wherein the manifold is configured to reverse the delivery of gas or liquid and the application of suction so that the one or more first ports is applying suction while the one of more second ports is delivering gas or liquid.
An endoscope for insertion into a body cavity of a patient, comprising:
- an elongate member having a proximal end and a distal end;
- one or more first ports disposed at or adjacent to the distal end of the elongate member, the one or more first ports being connected to a source of gas;
- a second set of ports disposed proximal to the one or more first ports, wherein each of the one or more first ports is in fluid communication with a lumen of the elongate member that delivers gas to the one or more first ports as suction is applied to the second set of ports;
- a controller configured to regulate pressure at the distal end of the elongate member;
- and
- a manifold, wherein the manifold is configured to reverse the delivery of gas or liquid and the application of suction so that the one or more first ports is applying suction while the one of more second ports is delivering gas or liquid.
