An at least partly implantable system for injecting a substance into a patient's body, in particular a penis erection stimulation system, comprises an infusion device (11) adapted for implantation inside the patient's body and at least one reservoir (R1, R2) adapted for implantation inside the patient's body in fluid connection with the infusion device to supply to the infusion device a substance to be injected into the patient's body. 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 housing at least in two different 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. |

1. An at least partly implantable system for injecting a drug into a patient's body, comprising an infusion device adapted for implantation inside the patient's body and at least one reservoir adapted for implantation inside the patient's body in fluid connection with the infusion device to supply to the infusion device a drug to be injected into the patient's body, wherein the reservoir comprises at least one first compartment accommodating or adapted to accommodate an infusion liquid and at least one second compartment accommodating or adapted to accommodate the drug in powder form for mixing with the infusion liquid of the at least one first compartment, the system further comprising a mixing chamber for mixing the infusion liquid from the at least one first compartment with the drug from one or more of the at least one second compartment, wherein the arrangement is such that the drug is releasable from the at least one second compartment into the mixing chamber in powder form so that, when infusion liquid from the at least one first compartment is urged through the mixing chamber towards the infusion device, the infusion liquid will take with it the drug released from the at least one second compartment, wherein the system further comprises at least one of:
a plate having two larger opposite sides being a first and second side, wherein the at least one compartment is mounted so as to open towards a first side of a plate and wherein the opening mechanism is adapted to act on the at least one second compartment so as to open to said first of the plate, and a tape wound up on a reel, wherein the at least one second compartment is mounted on the tape wound up on the reel. |
