Abstract: Creating a replica of an anatomical structure. At least some of the example embodiments are methods including: accepting a plurality of pictures of the anatomical structure of a subject; creating an object file that contains an initial model of an outside surface of the anatomical structure; cutting the initial model to a predetermined exterior shape circumscribing the anatomical structure, the cutting creates a positive model of the anatomical structure within the predetermined exterior shape; creating a negative model of the anatomical structure from the positive model; placing a stem tool object on an outside surface of the negative model in relationship to an orifice of the anatomical structure, and thereby creating a final negative model; printing, by way of a three-dimensional printer, the final negative model to create a negative mold; and casting the replica of the anatomical structure using the negative mold.

Abstract: Biological fluid collection. At least some of the illustrative embodiments are systems including a sleeve of elastomeric material and a receptacle coupled to the sleeve. The sleeve may include: first and second ends, each end comprising respectively a first and a second orifice; and a passage extending between the first and second orifices. The receptacle may include: a side wall and a bottom that define an interior volume and a height; and an entrance portion that defines an internal diameter, wherein the height of receptacle is at least half the internal diameter. The receptacle may mechanically couple to the sleeve such that the interior volume is fluidly coupled to the passage of the sleeve.
