Abstract:
1. An adjustable access device, comprising: a housing having an adjustable cannula extending therefrom with a tapering distal tip, the housing and the cannula defining a working channel extending therethrough, the adjustable cannula including a flexible band wound into a helical spring such that a proximal end of the flexible band is coupled to the housing and a distal end of the flexible band is positioned at a distal end of the adjustable cannula, the adjustable cannula having an insertion configuration with an increased length and decreased diameter for insertion into a tissue opening and a deployed configuration with a decreased length and increased diameter for anchoring within a tissue opening, and the housing including an actuator coupled to the proximal end of the flexible band and configured to rotate the proximal end of the flexible band to move the cannula between the insertion and deployed configurations.
