摘要:
An intraluminal device with controlled biodegradation is provided. The intraluminal device comprises a biodegradable tubular main body. An outer photodegradable layer is disposed over at least a portion of the intraluminal device. The photodegradable outer layer is chemically inert to the body fluids of the implanted region, thereby preventing premature biodegradation of the stent. Degradation of the outer photodegradable layer after a predetermined time occurs by irradiating the layer with UV light waves. After removal of the outer photodegradable layer, the tubular main body becomes exposed to the in vivo environment, thereby allowing biodegradation of the tubular main body.
