DILATION SYSTEMS AND RELATED METHODS |
摘要 |
Devices and methods permit dilation of a track of a body to any of a plurality of diameters using a single integrated device that can reach any of a plurality of expanded diameters upon actuation by a user of an actuating mechanism which directs and controls the dilation of a dilating element to which it is connected by a dial and transmission mechanism. A variety of dials, transmission mechanisms and dilating elements are disclosed which may be combined in a variety of ways. The dilating element comprises a spirally wound flat metal sheet locked in a first unexpanded configuration and unlocked to expand at the treatment site carrying out a dilatation.
