1. A system for treating chronic obstructive pulmonary disease body tissue comprising:
- a device that has a generally cylindrical shape and is open at a first end and at a second end;
a resilient sheath configured to mount to the first end of the device in a manner where a substantial portion of the sheath resides within the device;
a vacuum source for drawing target lung tissue into the sheath at the first end of the device; and
a severing tool.

Abstract
A resection device and method permits safe and efficient encapsulation, isolation and resection of body tissue. The device includes a sheath of flexible and severable material configured to receive the body tissue to be resectioned as it is drawn therein. The sheath may be expandable and held in an expanded condition as the body tissue to be resectioned is drawn into the sheath. Thereafter, the sheath is permitted to collapse about the body tissue to contain and constrict the body tissue. Once the body tissue to be resectioned is disposed in the sheath, the sheath is severed to resection the body tissue.

4. A method for treating chronic obstructive pulmonary disease comprising:
-
expanding a portion of a resilient sheath that has an open end configured to permit lung tissue to be received therethrough; mounting a portion of the expanded resilient sheath to a delivery device that is substantially rigid and that has an open end configured to receive the lung tissue therethrough; placing the delivery device at a location that is adjacent said lung tissue; drawing said lung tissue through the open end of said delivery device and through the open end of said resilient sheath; and releasing said expanded resilient sheath to permit said sheath to constrict said lung tissue. - View Dependent Claims (5, 6, 7, 8)
