ABSTRACT:
A medical device for manipulation of material in a tissue includes a sheath, an object engaging unit, and a flexible coupler. The object engaging unit has an operative end and a base. The flexible coupler includes a longitudinal axis and a distal portion; the distal portion is associated with the base of the object engaging unit and is bendable in an arc to various ranges. The flexible coupler confers lateral movement on the object engaging unit thereby permitting manipulation and/or retrieval of material lodged or disposed in heretofore often inaccessible tissue regions. The sheath has a longitudinal axis and a lumen. The object engaging unit is in a collapsed position when it is within the sheath lumen and an expanded position when it is extended beyond the sheath.
