A device for retrieval of organic and inorganic matter during a surgical procedure employing a camera and viewer to ascertain a removal target. The device has a catch basket formed of a plurality of radially oriented shaped wires extending an axis with gaps in-between for camera viewing and light transmission. A mouth aperture area is maximized by formation in a single plane and using wires of a shape to form an oval, crescent, or hexagon. A cauterizing snare may be formed using wires forming the mouth, may project from the catch basket, or may be used separate from the catch basket. Shaped memory material forming the wires maintains the shape of the catch basket, mouth, and snare, despite repeated compressions thereof into catheter housed conduits. |
