| 摘要 |
The present invention is a bioimplantable device for adjusting the position of and/or shielding selected tissues of a human body during radiation therapy. The device includes a selectively inflatable hollow structure formed from a biocompatible material, an inflation port in communication with the hollow structure effective to communicate an inflation material to within the hollow structure and at least one tissue fixation element disposed on the hollow structure. In another embodiment, the device is a multi-layer structure which can be implanted to block radiation and/or displace tissues from the path of the radiation. |
