Equipment and methods for preparing a person for placement of a subcutaneous prosthesis, e.g., are disclosed. An inflatable expander, such as an expandable bladder, is introduced under an area of skin to be stretched. A tube extends through the skin to a preferably valved fluid flow connector. The person whose skin is to be stretched can periodically introduce desired amounts of fluid, such as saline solution, into the expander by use of a patient controlled delivery machine ("PCD machine") which is connectible to the fluid flow connector. The PCD machine can be a syringe having an outlet fitting which is matable to the flow connector. Since the person controls the times and amounts of liquid added to the expander, there is a reduction in the time, cost, and discomfort encountered by the person in preparation for placement of a prosthesis under stretched area of skin.
