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.
