摘要： Some embodiments relate to a device for retrieving a body from within a tubular structure, the device having a proximal end and a distal end and comprising: a device body at the proximal end; a conduit extending away from the device body to the distal end and sized to be receivable in the tubular structure; at least one actuator operably associated with the device body; a first strand extending at least in part through the conduit; a second strand extending at least in part through the conduit; wherein the first and second strands are affixed at the distal end of the device, and wherein the second strand is wound around the first strand along at least a distal length of the first strand; wherein the at least one actuator is operable to cause the second strand to adopt an expanded state in which the second strand defines a trawl volume to catch the body for retrieval of the body from the tubular structure.
