Claim Text:
1. A specimen retrieval apparatus comprising: an elongated tubular member defining a longitudinal axis, a lumen extending therethrough, and having a proximal end and a distal end, the elongated tubular member being manipulatable to define a desired articulated configuration relative to the longitudinal axis and configured to maintain the desired articulated configuration after manipulation; a vacuum assembly coupled to the proximal end of the elongated tubular member and in communication with the lumen extending therethrough, the vacuum assembly configured to operate in a suction mode and in a pressure mode; a suction member disposed at the distal end of the elongated tubular member, the suction member defining an aperture disposed in fluid communication with the lumen of the elongated tubular member and a one-way valve disposed within the aperture, the suction member configured to suction a tissue specimen thereto when the vacuum assembly is operating in the suction mode, the one-way valve permitting the flow of fluid proximally therethrough and inhibiting the flow of fluid distally therethrough such that the suction member is maintained suctioned about the tissue specimen when the vacuum assembly is turned off and when the vacuum assembly is operating in the pressure mode; and a specimen retrieval bag disposed about the elongated tubular member towards the distal end thereof, the specimen retrieval bag including at least one chamber disposed in fluid communication with the lumen of the elongated tubular member, the at least one chamber being inflatable to deploy the specimen retrieval bag from an un-deployed state to a deployed state to surround the suction member and tissue specimen retained by the suction member when the vacuum assembly is operating in the pressure mode.
