1. An endoscopic suction device, comprising:
a conduit extending from a proximal end to a distal end along a longitudinal axis, the proximal end configured to be coupled to a vacuum source and the distal end configured to extend into a subject's body; and
a suction head at the distal end of the conduit, the suction head including a shape-memory alloy;
wherein the suction head includes a filter positioned at a junction between a proximal end of the suction head and the distal end of the conduit to prevent material from entering the conduit.
