The objective of the RELIEF project is to create a series of implantable devices that can be an effective solution to the problem of urinary incontinence. Urinary incontinence is a dysfunction that affects about 350 million people worldwide and which, according to estimates, will affect more than 400 million people in 2018. This is a problem that affects people of both sexes for several reasons including prostatectomy and bladder removal following tumors. In addition, urinary incontinence and, in general, voluntary control of urination are common problems for para and tetraplegic patients.
In particolar, the RELIEF project proposes, within 3 years, to engineer and certificate advanced prototypes of artificial sphincters. During the project two different solutions will be studied: a device to be inserted into the urethra (endouretral system) and a device to be positioned outside the urethral channel (extraurethral system). The first solution consists of an unidirectional polymeric valve that can be activated and deactivated by means of an external magnet. The second solution consists of a magnetic mechanism that guarantees continence by compression of the urethra and allows urination when required, deactivating this mechanism from the outside. The goal is to produce a device that is much simpler and much less invasive than currently available spinal urine (eg. AMS800).
RELIEF will benefit from the expertise of the Surgical Robotics and Allied Technical Area of the BioRobotics Institute, which has long-lasting experience in the development of mechatronic devices for both acute and chronic therapy. The RELIEF work group is also involved in the development of other artificial organs, such as artificial pancreas and artificial bladder.
