CLINICAL SYRINGE WITH ELECTRICAL STIMULATION ASPECTS

摘要

A treatment device (22) is provided for applying electrical energy to biological tissue in conjunction with injecting a composition. An injector (32) such as a syringe (32) has a reservoir (44) for the treatment composition and injection cannula (34). The cannula (34) can function as an electrode (36), and one or more additional electrodes (36). The electrodes (36) can each have tissue penetrating needles, or one or more of the electrodes (36) can have a surface bearing conductive contact part (136). The syringe (32) or injector (32) and a drive unit (82) that applies electrical power to the electrodes (36) are operable simultaneously or in a sequence. The treatment device (2) uses a disposable syringe (32) received in a carrier (66).
