The resorption of a medical implant can be controlled with the use of particles
embedded in a resorbable bulk material forming the implant or portion thereof.
The implant can be removed from a body of a mammal by natural biological mechanisms
after use. The resorption of the implant can involve swelling and/or hydrolyzing
of the particles within the implant upon contact with a body fluid such that porosity
and flow of fluid within the bulk material of the implant is increased. Resorption
of the implant may also involve the use of particles with magnetic properties embedded
within the implant such that an applied magnetic field causes the particles to
vibrate within the bulk material thereby increasing the porosity and thus the flow
of fluid, hence facilitating resorption of the implant. The resorption rate of
the implant can be controlled by modulating swelling, hydrolysis, or movement of
the embedded particles.
