A tool has a slot provided between a pair of extremities at its distal end. The devices and methods allow for the implantation of analyte-monitoring devices, such as glucose monitoring devices, that result in the delivery of a dependable flow of blood to deliver sample to the implanted device. As the result, the linearity of the output can be improved over variation of both the temperature and the position. The docking station is provided with a specially configured removable connecting sleeve which may be used to connect a particular make and model of handheld wireless telephone to the docking station. The system can store and process the data locally, or the data can be transferred to other entities for storage, processing, analysis or other purposes. One end of the auxiliary arm is engaged with the second connecting portion.
