Abstract
A device that comprises a tubular-shaped body that is insertable into a body passageway or cavity, in particular the urethra, and that has an exterior surface having one or more anchors located thereon that aid in movement of the device with a minimum of trauma during placement and that aid in securing the device within the passageway or cavity during use. The device may be inserted into either the urethra, bladder neck, or bladder. The anchors can vary in height, length, number, compressiveness, axial placement, material characteristics, and helix angle. According to a further aspect, the one or more anchors are in the form of partial spiral helixes that function to move and secure the device within the human urethra. The partial spiral helixes have structures that allow for the longitudinal movement of the device during positioning procedures.
