摘要:
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.
