Abstract
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.

An expandable access system having contracted and expanded configurations, the system comprising:
- an expandable access device having a substantially helix or wrapped shape defining an access passage;
- an expandable trocar having a trocar passage and being positionable in at least a portion of the access device;
- and
- a sleeve disposed over at least a portion of the access device and configured to resist radial expansion of the access device,
- wherein expansion of the trocar radially expands the access device from the contracted configuration toward the expanded configuration.
An expandable access system having contracted and expanded conditions, the system comprising:
- an expandable access device having a substantially wrapped shape and an access passage;
- an expandable trocar having a trocar passage and being positionable in at least a portion of the access device;
- and
- a sleeve disposed over at least a portion of the access device and configured to resist radial expansion of the access device,
