A protecting means for non-invasive procedures, for example endoluminal or laparoscopic procedures, comprises a sheath (10) extending from a distal end (10a) to a proximal end, in which the sheath comprises at least one inflatable channel (12) having an opening and being suitable for receiving a fluid injected through said opening whereby said fluid injected into the inflatable channel through said opening inflates at least one portion of the sheath. The inflatable channel (12) comprises a plurality of longitudinal inflatable segments (14) and a plurality of annular inflatable segments (16) connected to the longitudinal inflatable segments in shape of a frame or net of the sheath (10). The protecting means further comprises an outer sleeve (20) and an inner sleeve (22) forming a gap (24) that comprises the plurality of longitudinal inflatable segments (14) and the plurality of annular inflatable segments (16) connected to the longitudinal inflatable segments. The sleeves are made by a transparent material.
