Abstract
A sheath for receiving an ultrasonic probe and for defining the relative position of the probe with respect to a biopsy gun or a rigid needle is used for precise placement of the biopsy gun or needle tip in a structure. The sheath may comprise a keyhole-shaped slot for placement of a rigid needle through a puncture separate from a surgical port through which the sheath itself and the probe are introduced. A flexible catheter can thus be placed in a structure, using the ultrasonic probe to monitor its placement, followed by removal of the probe sheath and surgical port, leaving the catheter in place.
