Patent ID: 7811256

Claim:
A medical device comprising: a sheath comprising an extended distal end portion, a proximal end portion, and parallel and segregated first and second lumens defined therethrough; a handle fixedly connected to the proximal end portion of the sheath, the handle comprising an operator comprising a trigger pivotably mounted upon the handle that is translatable between a first position and a second position, wherein the trigger is biased into the first position; a flow path defined within the handle in fluid communication with the proximal end portion of the first lumen of the sheath, wherein the operator is configured to substantially block the flow path when the trigger is in the second position and allow flow therethrough when the trigger is in the first position, wherein the flow path comprises a first inlet portion that is configured to communicate with a remote source of suction; and a second inlet portion configured to receive a tool therethrough and allow the tool to extend through the second lumen of the sheath; and a lock slidably disposed upon the handle for selective engagement with the trigger to maintain the trigger in the second position wherein the operator comprises a valve seat that translates with motion of the trigger between the first and second potions, wherein the valve seat rests upon a first pin oriented substantially in the direction of travel of the valve seat, and further comprising a second pin connected with the first pin, the second pin being fixably mounted to the first pin.
