FIELD: medicine. ^ SUBSTANCE: invention relates to medicine and deals with intraluminal device, intended for introduction into body canal. Device contains thin tube, sufficiently rigid not to bend and sufficiently flexible to follow curves of body canal. Tube has first end for introduction into body canal, second end, connected with receiving device, and introduced part, enclosed between first end and place, located between two ends. Introduced part is intended for partial introduction into body canal. Envelope is formed by two overlaid on each other sheets of plastic material, connected to each other, at least, on sides, in fact, parallel to tube by means of one connecting strap with width, at least, equal to minimal value, and intended for air-proof closing before application of introduced part of thin tube. Part of preferable division for hole formation contains cut, which lessens width of connecting strap and forms initial site for tearing two sheets of plastic material, which represents oriented polymer. Direction of orientation of oriented polymer is transverse with respect to the length of tube of intraluminal device. ^ EFFECT: invention makes it possible to separate sheets of envelope in convenient way. ^ 9 cl, 6 dwg |
