A method for producing an endoscopic drape includes positioning a portion of a sheath of flexible material (22) in abutment with a joining portion (23) of a first housing piece (14). A joining portion (24) of a second housing piece (16) is positioned close to joining portion (23) and the joining portions are then joined together, for example, by ultrasonic welding. This forms a housing (12) in which the portion of the sheath (22) is entrapped between the first housing piece (14) and the second housing piece (16). The portion of the sheath (22) may be joined to the first housing piece (14) by a thermoplastic gasket or o-ring (35) prior to joining the first and second housing pieces (14, 16) to improve the seal between the sheath (22) and the housing (12). The housing (12) includes a clear lens or window (27) that provides an optical pathway through the housing and also provides a sterility barrier. |
