A device and method for treating a wound of a patient with negative pressure is provided. The device comprises a heat-assisted pump system. The pump system can be powered in part by heat derived from the patient. The pump system may be configured to be highly planar, light weight, and portable. The pump system may comprise a Stirling engine or a thermal acoustic engine.

A penis erection stimulation system 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 reservoir and a pump are also 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 is 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. The drive unit is configured to laterally displace the tip end of at least one infusion needle in at least two different lateral directions to different penetration sites within said at least one penetration area.

A wireless power transfer system is provided. The system includes an external transmit resonator and an implantable receive resonator. The transmit resonator is configured to transmit wireless power, wherein the external transmit resonator includes one of i) one or more loops of Litz wire and ii) a plurality of stacked plates. The implantable receive resonator is configured to receive the transmitted wireless power from the external transmit resonator, wherein the implantable receive resonator is configured to power a ventricular assist device (VAD) implanted in a subject using the received wireless power. The implantable receive resonator includes the other of i) the one or more loops of Litz wire and ii) the plurality of stacked plates.

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, at least one reservoir (R.sub.1, R.sub.2) 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, and a cooling device for keeping the content within at least one compartment of the reservoir at a temperature below 37 C. The reservoir preferably 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, wherein the at least one second compartment is cooled by means of the cooling device. 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.

The present invention provides compositions and methods for treating a subject in need of treatment with testosterone, including introducing testosterone into the subject subcutaneously, intradermally, or intramuscularly, from a needle assisted jet injection device.

This application concerns pharmaceutical compositions comprising cannabinoids which are suitable for subcutaneous administration in human subjects. Thus, this application concerns pharmaceutical compositions for subcutaneous administration. The pharmaceutical compositions according to the invention are particularly suitable for subcutaneous administration, which is advantageous for improving bioavailability and reducing toxicity.

An HME has a housing moulded in two parts of a thick, thermally-insulative foamed plastics to form an enlarged central region and opposite end walls. Separate patient and machine end couplings are bonded to openings in the end walls. The two housing parts are bonded end to end about an HME element formed by a strip of treated corrugated paper wound about a support sleeve.
