Devices - PENIS PUMP
The device helps draw blood into the penis by applying negative pressure. This type of device is sometimes referred to as penis pump and may be used just prior to sexual intercourse. Several types of FDA approved vacuum therapy devices are available with a doctor's prescription.
A vacuum device can be used to produce an erection. Elements of the device include the cylinder, a pump to create a vacuum, and a constriction ring to be placed at the base of the penis after an erection has been obtained in order to maintain the erection.
