摘要:
Embodiments may include an expandable access system having contracted and expanded configurations. The system and methods may include an expandable access device having a helix or wrapped shape. Embodiments may include a cannula, stent, needle, trocar, introducer, fastener, and/or any other devices disclosed herein. Embodiments may also include an expandable trocar positionable in at least a portion of the access device. A sleeve or band may be disposed over at least a portion of the access device and configured to resist radial expansion of the access device. Expansion of the trocar and/or receipt of an object may radially expand the access device between a contracted configuration and an expanded configuration.
