[The implantation of a nitinol endoprosthesis in treating strictures and atresias of the uterine cervical canal].

The paper is concerned with the description of the first experience in a new method of roentgen endoprosthetics of the cervical canal of the uterus using a nitinol spiral prosthesis. The spiral has a shape memory effect. Prostheses were implanted to 13 patients with strictures or atresia of the cervical canal after bougienage for a period of 193 days.

[Experimental-morphological study of the roentgeno-endovascular prosthesis].

The authors presented the results of experimental studies on 36 dogs: 66 endovascular spiral wire prostheses made of a metal alloy with a shape "memory" effect were implanted in the aorta and major arteries via an angiographic catheter. Long-term results were followed-up over a period of 14 mos. and demonstrated a good and prolonged permeability of the nitinol prostheses.
