The present invention is a nerve stimulation system for treating pain in a patient, the system comprising an implantable device (100) having: a housing (18) having a power source and at least one stimulation electrode (17) arranged on the housing (18) and in electrical communication with the power source, the stimulation electrode (17) adapted to transmit an electrical signal for stimulating at least one nerve cell of the patient, and wherein the power in the power source is wirelessly generated. The fact that the device (100) has at least one stimulation electrode (17) arranged on the housing (18) advantageously provides a compact and miniature device for simple, minimally invasive implantation into a patient to treat pain. The size of said device (100) allows it to work with commonly used injectors such as a standard medical syringe and a stainless steel needle. Further, the device (100) can be powered wirelessly, which allows said device (100) to be implanted for a long period of time.本發明係一種神經刺激系統俾治療一病患體內之疼痛,該系統包含一植入式裝置具有:一外殼具有一電源;以及至少一刺激電極配置在該外殼上並與該電源電氣通訊,該刺激電極適於傳送一電氣信號俾刺激該病患之至少一神經細胞,以及其中該電源中之該電力係無線式產生。該裝置具有至少一刺激電極配置在該外殼上的事實係有利地提供一緊密且小型之裝置俾簡單、最低侵入式植入至一病患體內以治療疼痛。該裝置之大小容許該裝置與通用注射器諸如一標準醫療注射器及一不銹鋼針頭一起作業。此外,該裝置可被無線式供給電力,而此舉容許該裝置被植入達一長時期。100‧‧‧刺激裝置/裝置113‧‧‧天線/RF天線117‧‧‧刺激電極/電極119‧‧‧DAC/ADC120‧‧‧脈波產生模組121‧‧‧開關122‧‧‧耦接模組123‧‧‧整流器模組124‧‧‧儲存器單元125‧‧‧電力管理模組126‧‧‧電壓產生器127‧‧‧溫度轉換器128‧‧‧信號解調器/時脈擷取器/電力-開啟-重設129‧‧‧多工器130‧‧‧負載調變器131‧‧‧RF限制器132‧‧‧電壓限制器133‧‧‧數位基帶
