The reservoir comprises at least one first compartment accommodating or adapted to accommodate a first substance and at least one second compartment accommodating or adapted to accommodate a second substance, in particular a drug for stimulating penis erection. As a penis erection stimulation system, the infusion device preferably comprises one or more infusion needles disposed within and implanted along with one or more housings adjacent the patient's left and right corpora cavernosa. A pump may be implanted inside the patient's body to supply the infusion needle with infusion liquid. A drive unit also adapted for implantation inside the patient's body may be arranged for advancing and retracting the tip end of the infusion needle such that it penetrates the house at least in two difference penetration areas either simultaneously or in immediate time succession, thereby injecting drugs along with the infusion liquid into the patient's body for stimulating penis erection.14/24 FIG 19 ,,100 T A C2 31 GAS M2 p32R 23 R2 24 219 26 M 12 11 D F 7
