Due to the varying complications, different modifications of<unk>  have been developed to improve outcomes. Adjustable<unk>  has been available since 1972, allowing variable constriction. FloWatch (Leman Medical, Geneva, Switzerland: www.lemanmedical.com), an adjustable band, was created and has successfully been tested to overcome complications due to non-optimal sizing of the band. FloWatch is a wireless, battery-free, implantable device that allows the band size to be adjusted without the need for additional surgeries or other invasive procedures. The narrowing of the pulmonary<unk>  can be controlled weeks or even months after the operation. Reports also show that the recovery period in patients that obtained the FloWatch device was faster and smoother in comparison to those that received the traditional<unk>  method. However FloWatch is only suitable for children with a body weight ranging from 3 kg to10kg.
