1. A device comprising:
a flexible tubular member having a proximal end, a distal end, and channel extending substantially between the proximal end and the distal end;
a stiffening sleeve positioned at the distal end of the tubular member to provide stiffness thereto so that a removable procedural tool can be attached to the tubular member;
an elongated non-elastic tether situated within the channel of the tubular member and—fixed at its distal end to a point about a distal portion of the tubular member, such that the tether can be held in tension to minimize axial stretching of the tubular member to prevent the tubular member from axially springing back to a neutral state, during use;
a connector arranged at the proximal end of the flexible tubular member, wherein the connector is at least one of a Y-connector and a T-connector; and
an indicator membrane on the connector configured to provide tactile feedback to reflect positive or negative pressure being applied to the tubular member;
wherein the elongated non-elastic tether is directly coupled to the connector.
