1. A medical device comprising:
a rim defining a loop in a plane and defining a width measured perpendicular to the plane, wherein the rim has two openings at a distal end of the rim;
at least one wire coupled to the distal end of the rim and extending proximally from the distal end out of the plane to a proximal end of the rim, the at least one wire having a cross-sectional dimension measured perpendicular to a longitudinal axis of the at least one wire, the cross-sectional dimension being smaller than the width of the rim, wherein the at least one wire extends through the two openings, wherein a portion of the at least one wire is outside the loop and distal to the rim; and
a sheath configured to cover at least a portion of the rim and a portion of the at least one wire.
