Balloon-dilatable arterial banding prosthesis: experimental study
DJ Vince, JA Culham and GP Taylor
Two arterial banding prostheses were developed that could be dilated by an
intraluminal balloon dilator. One prosthesis consisted of radiopaque
umbilical tape with a pleat secured by four 8-0 silk sutures thinly coated
with silicone type A medical adhesive. This design was used to band the
main pulmonary artery in five dogs, the subclavian artery in five, and the
aorta in one. The second prosthesis, a stainless steel fatigued helix
encased in a siliconized shield, was used to band the main pulmonary artery
in two dogs and the descending aorta in two. After a mean duration of 89
days the bands were dilated with an intraluminal balloon dilator at 6 atm
(608 kPa) of pressure for 30 seconds. In all 15 experiments the bands
dilated and the gradient at the band was reduced. The stainless steel helix
was more successful and has technical advantages for clinical application.
