An endoscope having an operating handle including a handle housing arranged at a proximal end and an insertion tube extending from the handle towards a distal end of the endoscope and terminating in a steerable tip part at the distal end of the endoscope, the endoscope further including a control mechanism with a Bowden cable having an outer guide tube having a first length between a proximal end and a distal end of the outer guide tube and an inner pull-wire having a second length between a proximal end and a distal end of the inner pull-wire, the second length being longer than the first length, the proximal end of the outer guide tube is affixed to the operating handle by an adhesive.

A sliding motion transfer member (22) for the kinematic chain of an actuator mechanism of an endoscope. The sliding motion transfer member (22) has a proximal end and a distal end (21). The sliding motion transfer member (22) is adapted to receive motion activation input and to move in a sliding manner in response to said motion activation input, thereby transferring motion to an elongate motion transmission member (27) extending from the distal end (21) of the sliding motion transfer member (20). The sliding motion transfer member (22) comprises a first passage (36) adapted for receiving a proximal section of said elongate motion transmission member (20) and an adhesive.

An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves.
