SELF-EXPANDING STENTS INTO THE HOLLOW ORGANS OPENING INSTALLATION METHOD

摘要

FIELD: medicine.;SUBSTANCE: invention relates to the medicine, namely to surgery, endoscopy, and can be used with necessity of the self-expanding stents delivery to the narrowed by scar or inflammatory process, as well as hard-to-reach areas of hollow organs. For this, fixing the stent in the compressed state, placing it in the bio-absorbable tubular woven sleeve, formed by the stent spiral winding with the thread, which ends are fixed to the stent edges. Thread is made of a material that provides the possibility of its dissolution with a given duration, necessary for the stent opening. One end of the stent contains the free “lasso” loop. Then inserting the stent into the hollow organ opening, grabbing by the “lasso” loop with introduced through the endoscope instrumental channel biopsy forceps, and bringing behind the narrowing area. After the stent opening, removing and extracting the forceps.;EFFECT: method reduces the morbidity while reducing the stent installation duration by using the smaller diameter delivery device due to the use of a water-soluble thread, which can be carried out through the endoscope working channel, in addition, during the stent dislocation, its extraction, recharging and reinstallation are possible without use of the new product.;9 cl, 1 dwg, 1 ex
