Abstract
A dilation system and method for accessing a surgical target site to perform surgical procedures. In one version, the dilation system includes a dilation assembly and an actuating mechanism. The dilation assembly comprises plurality of dilator segments. The actuating mechanism is operably associated with the dilator segments so as to cause the dilator segments to move from a collapsed state to an expanded state.
Claims20
A dilation system, comprising:
- a plurality of dilator segments, each dilator segment having a length, a proximal end, a distal end, an inner side, and an outer side, the dilator segments forming a tubular dilator having a longitudinal axis, at least one of the dilator segments including an electrode assembly;
- and
- an actuating mechanism operably associated with the dilator segments in a way to move the dilator segments radially from a collapsed state to an expanded state,
- wherein the dilator segments are rotatable relative to at least a portion of the actuating mechanism about the longitudinal axis.

A dilation system, comprising:
- a plurality of dilator segments, each dilator segment having a length, a proximal end, a distal end, an inner side, and an outer side, the dilator segments forming a tubular dilator having a longitudinal axis, at least one of the dilator segments having a channel formed in the outer surface thereof and extending the length of the dilator segment for receiving a probe;
- and
- an actuating mechanism operably associated with the dilator segments in a way to move the dilator segments radially from a collapsed state to an expanded state,
- wherein the dilator segments are rotatable relative to at least a portion of the actuating mechanism about the longitudinal axis.
