Abstract
A grid sheath that holds a medical instrument in place in order to insert treatment seeds into a patient. The grid sheath includes a sheath unit in which the medical instrument is fitted therein, whereby the medical instrument is capable of sliding movement within the sheath unit. The grid sheath also includes at least one plate support rod, which is preferably adjustable and that is integral with a distal end of the sheath unit. The grid sheath further includes a push plate, that is integral with a distal end of the plate support rod. When the medical instrument is placed in position with respect to a grid template, the medical instrument is engaged with a needle in a hole of the grid template, and the push plate rests against a distal surface of the grid template. As the medical instrument is actuated to deposit seeds and thereby to move away from the grid template to deposit more seeds in another position within the patient, the push plate provides for registration of the medical instrument with respect to the grid template while this is occurring.
