A biomedical device of a smart
elastomer, more particularly relating to a class of
low modulus elastomers with dispersed, aligned
magnetic nanoparticles therein that allow for controlling the
flexural modulus of the device and engaged tissue in response to an applied
magnetic field. An exemplary embodiment is used for treating obstructive
airway syndrome wherein one or more implants including an
elastomer magnetic
nanocomposite are placed in a patient's
soft palate. During sleep, a source of
magnetic flux is applied to stiffen the implants to dampen vibrations in tissue which occur in snoring and
sleep apnea episodes. The
magnetic flux is provided by a permanent
magnet or by a
magnetic field source coupled to a controller for modulating the stiffness of the
implant(s). In similar embodiments, the controlled modulus implants can be used to treat various anatomic structures such as upper
airway tissue,
oral cavity tissue,
gastrointestinal tract tissue, urinary tract tissue, cardiovascular tissue,
muscle tissue, penile tissue, sphincters and
skin.
