Claim:
1. A medical device comprising: a member having a proximal end, a distal end, and a lumen extending therebetween; a hood coupled to a distal portion of the member, the hood defining a distal-facing cavity configured to receive tissue; and a limiter configured to selectively control a volume of tissue received in the hood, the limiter including a distalmost surface configured to abut tissue to limit proximal movement of the tissue into the hood, wherein movement of the limiter controls the volume of tissue received by adjusting a length of the cavity without adjusting a diameter of the cavity, where the length of the cavity is measured from the distalmost surface of the limiter to a distalmost end of the hood, and wherein the limiter is disposed within the cavity and moves relative to a proximal end of the cavity, wherein the limiter includes a suction tube.
