STOMA DILATOR |
摘要 |
A stoma dilator is provided which has a base dilator and a plurality of dilators which are coaxially disposed over the base dilator. The base dilator has a hub and an opening therethrough. The base dilator is configured to be positioned over a wire into a patient's tissue. Each of the plurality of dilators has a tapered distal end, a proximal end, and a tubular body, and are held in separated, telescoping position by the dilator positioner such that a portion of each distal end is exposed from beneath another dilator and is graspable by a health care practitioner for movement such that a smaller diameter dilator does not become inaccessible inside of a larger diameter dilator. The stoma dilator may include a hollow sheath positioned over an outermost dilator. The sheath is configured to hold open a tissue opening created by the plurality of dilators. The base dilator and the plurality of dilators may be removed while the sheath remains in a tissue opening. Another device may be inserted through the sheath, and the sheath may be peeled away therefrom. |
