摘要：
A stoma dilator is provided which has a base dilator and a plurality of dilatorswhich are coaxially disposed over the base dilator. The base dilator has a huband an opening therethrough. The base dilator is configured to be positionedover a wire into a patient?s tissue. Each of the plurality of dilators has a tapereddistal end, a proximal end, and a tubular body, and are held in separated, telescopingposition by the dilator positioner such that a portion of each distal end is exposedfrom beneath another dilator and is graspable by a health care practitioner formovement such that a smaller diameter dilator does not become inaccessible insideof a larger diameter dilator. The stoma dilator may include a hollow sheath positionedover an outermost dilator. The sheath is configured to hold open a tissue openingcreated by the plurality of dilators. The base dilator and the plurality of dilatorsmay be removed while the sheath remains in a tissue opening. Another device maybe inserted through the sheath, and the sheath may be peeled away therefrom.
