Three different internal airway stents were studied in an animal model of tracheomalacia: the Palmaz stent (Johnson & Johnson, Warren, New Jersey) and the NIR stent (Medinol Ltd., Tel Aviv, Israel)--both made of stainless steel in the form of tubular mesh--and the Nitinol stent, made of nickel-titanium formed into a spiral shape. All three stents could be adequately stabilized in the malacic tracheal segment. The Nitinol stent (Medinol Ltd., Tel Aviv, Israel) proved to be less reactive to the tracheal mucosa, demonstrated higher biocompatibility with significantly less granulation tissue formation, and showed superior radial resistance. Extraction of the Nitinol stent also proved to be much smoother. This stent may be the stent of choice in the treatment of tracheo- and bronchomalacia.
帕尔马兹支架（强生公司，新泽西州沃伦）和NIR支架（美迪诺公司，以色列特拉维夫），二者均由管状网状不锈钢制成，以及由镍钛合金制成螺旋形状的镍钛诺支架。所有三种支架均可在软化的气管段中充分稳定。镍钛诺支架（美迪诺公司，以色列特拉维夫）对气管黏膜的反应性较低，表现出更高的生物相容性，肉芽组织形成明显较少，并且具有出色的径向抵抗力。镍钛诺支架的取出也被证明要顺利得多。这种支架可能是治疗气管和支气管软化的首选支架。
