The first true hypodermic syringe was created by Alexander Wood in 1853. He modified a regular syringe, which at that time was used for treating birthmarks, by adding a needle. He then used this new device for introducing morphine into the skin of patients who suffered from sleeping disorders.

Ectopic pregnancies are frequently due to an inability of the fertilized egg to make its way through a Fallopian tube into the uterus.
