Abstract: A disposable prostrate treatment template and a separate mounting frame to mount the template to a seed implant device is provided. The template includes a template body having a plurality of apertures extending therethrough; fasteners for removably securing said template to said mounting frame; suture wings extending from said template body to facilitate suturing of said template to a patient; and belt loops sized to receive a belt to secure the template to a patient. The template body is made from a rigid body frame and a polymer portion molded to said body frame. The body frame includes at least a pair of spaced apart legs and a cross-member extending between and connecting the legs to define a center area of the body in which the apertures are positioned. The apertures include at least one detent in the aperture and a flared entrance to the aperture. To align the template on the frame, the frame includes pins, and the template includes holes (preferably in the body frame) through which the pins extend.
