Abstract: The present embodiments provide an elongate medical device comprising a plurality of strands twisted in a generally helical manner to form a tubular shape having a longitudinal axis. A first strand of the plurality of strands is moveable with respect to at least a second strand of the plurality of strands. Actuation of the one or more strands may perform a medical function or actuate an associated distal component. A working lumen of the tubular member may remain unobstructed for delivery of medical components or fluids.

Abstract: A cryopreservation device for storing reproductive biological material is provided. The device comprises an elongate first member includes an elongate first member extending between a distal end and a proximal end, a first bulge portion disposed around a circumference of the first member, and a trough defined within the first member, the trough being configured to receive a reproductive biological sample thereon. A second member includes a second member with a lumen defined therethrough. The second member is configured to slide over the first member and the inner diameter of the second member is similar to an outer diameter of the bulge portion to form a seal between the first and second members.
