Claim Text:
1. An apparatus for treating a proliferative disorder in a patient comprising: an implantable rigid member having a proximal end and a distal end, the implantable rigid member comprising a plurality of lumen openings extending longitudinally within the implantable rigid member, and wherein the proximal end of the implantable rigid member defines a lock opening; a plurality of separate flexible dosing lumens, each having a proximal end and a distal end, wherein each distal end of each dosing lumen extends into a different one of the plurality of lumen openings of the implantable rigid member and wherein the distal end of each dosing lumen is spaced apart from the proximal end of the implantable rigid member; a hub discrete from the implantable rigid member and disposed about the plurality of dosing lumens, wherein the hub defines a slot defined by an outer circumferential surface of the hub; and a stylet comprising a shaft having a distal end and a proximal end and a key feature at the distal end of the shaft, wherein an exterior of the shaft has a uniform shape along a length of the shaft from the proximal end of the shaft to the distal end of the shaft and wherein the key feature removably mates with the lock opening of the implantable rigid member, and wherein the proximal end removably mates with the slot defined by the hub, such that mating engagement between the stylet and both the lock opening and the slot allows for a one-to-one axial rotation of the implantable rigid member and the hub, whereby an axial rotation of the stylet causes a corresponding axial rotation of the implantable rigid member and the hub.
