UCSF vascular surgeons develop new technique to repair aortic arch aneurysm
...pisode. Using a wire-thin catheter, the UCSF team inserted a specially designed graft through the right carotid artery on the side of the neck. The graft, a fabric tube that incorporates metallic threads (to offer structural support), was then guided into the arched part of the aorta, which carries blood to ...High blood pressure, fatty deposits are 'bit players' in bulging arteries

This antigen DNA is inserted into a "targeting vector," the replication-deficient Samonella typhimurium bacteria, which direct the DNA to lymph nodes in the gut--the so-called Peyer's patches.
