[Perorally insertable endotracheal stents made from NiTi memory alloy--an experimental animal study].
NiTi prostheses were perorally inserted in 12 rabbits. The spiral prostheses were overgrown by normal tracheal epithelium over time. No adverse effects due to impairment of the mucociliary clearance and no chondromalacia occurred. We conclude that perorally insertable prostheses made of the shape-memory alloy NiTi may be used as endotracheal or endobronchial prostheses.
