Abstract
A method of using a suction device to remove an object from a subject's body includes extending a suction device into the body through a lumen of a medical device and expanding the suction head from a contracted configuration to an expanded configuration within the body. The suction head may be provided at a distal end of an elongate conduit. The method may also include applying suction to move the object into the expanded suction head, and removing the suction device with the object from the body.
Claims5
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.
