Embodiments of the present invention relate to systems, methods, and apparatus for introducing and/or controlling a snare in a lumen (e.g., a lumen of a catheter tube, a body lumen, etc.). In one example, a snare loading device can reduce the size of a loop on a snare to allow the snare to be inserted into the catheter tube. Furthermore, before and/or after insertion of the snare into the catheter tube, the snare loading device can control the snare, by transferring motion thereto.

Device of inserting and controlling a snare

Apparatus, assemblies, and methods for capturing objects within a body are disclosed. A surgical snare device includes a steerable deflection portion with a steerable distal tip. An interface is linked to the steerable deflection portion to selectively manipulate the distal tip. A snare loop disposed at the distal tip can have a length that remains substantially constant as the distal tip is deflected and the snare loop moves in concert with the distal tip. The distal tip may deflect up to at least one-hundred eighty degrees, while the snare loop moves a corresponding amount. A method includes extending a snare through a body lumen and to a location near an object. The snare may have a loop that changes positions while maintaining the same length. The loop may be placed around an object and then used to retrieve the object from the body lumen.
