摘要

A protecting means for non-invasive procedures, for example endoluminal o r laparoscopic procedures, comprises a sheath (10) extending from a distal e nd (10a) to a proximal end, in which the sheath comprises at least one infla table channel (12) having an opening and being suitable for receiving a flui d injected through said opening whereby said fluid injected into the inflata ble channel through said opening inflates at least one portion of the sheath . The inflatable channel (12) comprises a plurality of longitudinal inflatab le segments (14) and a plurality of annular inflatable segments (16) connect ed 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) an d an inner sleeve (22) forming a gap (24) that comprises the plurality of lo ngitudinal 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.
