Abstract: A biopsy needle accessory including a shaft with a first end, a second end, and a passageway extending between the first end and the second end. The shaft includes a circumferential wall, an aperture formed in the circumferential wall, and a ramp positioned within the passageway at the aperture. A biopsy needle is inserted through the passageway and extends through the aperture at an angle.

Abstract: A multi-dose dispenser comprising an inner housing (16) and an outer housing (12), the inner housing (16) being movable within the outer housing (12) for a defined distance, a plunger rod (20) comprising a shaft (66) mounted within the inner housing (16), the shaft (66) having a plurality of spaced apart teeth (68) formed on the shaft (66), an actuator (22) located at one end of the shaft (66), the inner housing (16) having at least one pawl (70) arranged to engage with the teeth (68), a syringe (74) mounted interiorly of the inner housing (16), the syringe (74) being arranged such that the shaft (66) engages with a plunger within the syringe (74), and a spring member (18), the spring member (18) being biased between the inner housing (16) and the outer housing (12).
