Medical device for providing access
First Claim
1. A medical device for providing access to an internal space in a patient, the device comprising:
- a first elongate member having proximal end, a distal end, and an internal lumen;
a second elongate member having an open proximal end, an open distal end, and an internal lumen providing a passagweay extending therethrough;
wherein the first member is releasably attachable to the second member to provide a generally continuous fluid passageway, and such that the distal end of the first member is positioned intermediate the proximal and distal ends of the second member upon attachment of the second member to the first member.

Abstract
The invention provides, in one embodiment, a multifunctional, multi-piece medical device and related method for providing access to an internal body cavity, such as for use with a vacuum lift shell. The device can include a cannula and a cannula extension. The device provides a conduit between the external environment and operative field inside the patient'"'"'s body during medical procedures, including diagnostic, therapeutic and surgical procedures. The invention allows entry and exit of air or gas to help create and maintain the operative field. The invention can be used to provide an open and unobstructed working path, and allows the operative space to be maintained at ambient conditions of pressure and temperature.
