According to embodiments of the present invention, a passive counter flow free microfluidic device for sorting a sample of flagellated cells is provided. The passive counter flow free microfluidic device includes an input reservoir configured to receive the sample of flagellated cells, an output reservoir positioned downstream of the input reservoir, the output reservoir configured to collect the flagellated cells that are sorted, and a plurality of microchannel sections arranged sequentially and in fluid communication with each other between the input reservoir and the output reservoir, and designed to define a closed microchannel system between the input reservoir and the output reservoir, wherein each microchannel section comprises at least one microchannel, wherein an inlet of the microchannel of a first microchannel section of the plurality of microchannel sections is connected to the input reservoir, wherein an outlet of the microchannel of a last microchannel section of the plurality of microchannel sections is connected to the output reservoir, and wherein, for each microchannel section, the total volume of the microchannels of one microchannel section of the plurality of microchannel sections is larger than that of the respective in said downstream direction subsequent microchannel section of the plurality of microchannel sections for sorting the flagellated cells when the flagellated cells move from the input reservoir to the output reservoir.

A device for extracting and collecting blood from a delivered placenta comprising a compartment to contain and support a delivered placenta and umbilical cord. The compartment includes a flexible membrane which can be displaced (preferably under the influence of a fluid (preferably gas) pressure differential between the compartment side and non compartment side of the membrane) to impart onto the placenta a pressure to encourage the displacement of fluid carried by the placenta towards the umbilical cord. The compartment includes at least one outlet opening via which the umbilical cord can extend (preferably in a sealed manner) to allow the flexible membrane pressure induced flow of fluid carried by the placenta to displace from the compartment for external to the compartment collection of the fluid.

Treatment or prophylaxis of persistent penile erection resulting from, for example, physiological dysfunction, trauma, surgical intervention, or chemical induction. The method of the present invention is practiced by the administration of an agent capable of inducing, promoting, or otherwise facilitating contraction of the cavernosum. Another aspect of the present invention provides a composition comprising a cavernosum contraction-inducing, -promoting, or -facilitating agent. In one embodiment, the agents of the present invention are prostaglandins or functional derivatives, homologous, analogues, agonists, mimetics, or metabolites thereof. This invention also provides a means for diagnosing the physiological basis behind penile dysfunction.
