A method and apparatus for remotely cannulating a body part are disclosed. The apparatus is an endoscopic cannulation apparatus having a fluid stasis assembly and a coring assembly. The fluid stasis assembly allows for the penetration of the body part and deployment of an occlusive device to prevent the escape of fluid during the coring and cannulation of the body part. The cannulation assembly allows for the coring of the body part without the introduction of air bubbles or other embolic materials into the patient. The method of the invention provides for the remote coring and cannulation of a body part such as a heart, blood vessels, the stomach, intestines, and other body parts with a sealed apparatus that may be de-aired to lessen the risk of the introduction of emboli into a system.
