摘要： A vessel occluder is disposed inside a principal blood vessel for occluding tributary blood vessels inside the principal blood vessel while still allowing blood to flow through the principal vessel. The vessel occluder includes a support structure and associated membrane that can be collapsed for insertion into the principal vessel. Once inserted at the desired location the support structure is allowed to expand, forcing the membrane to contact the inner walls of the vessel with sufficient force to occlude the openings of the tributary vessels.

摘要： A radiation attenuation corridor couples a radiation therapy room and a control room. The radiation attenuation corridor is made of a material that substantially absorbs ionizing radiation and substantially blocks the transmission of the ionizing radiation. Specific wall portions at the entrance of the corridor are covered with borated polyethylene (BPE). Specific wall portions diverge from an axis defined by the corridor by from about 10 degrees to about 45 degrees. The corridor thus leads out of the room and angles laterally across the wall of the therapy room, before angling again and opening to a safe room. The added angles in the radiation corridor increase the distance of radiation travel, and make the path more indirect, thereby increasing the contact of the radiation emissions with the radiation shielding and further attenuating the radiation.
