The Digitimer DS7AP Muscle Locating Stimulator has been designed to meet the specific requirements of paediatric surgeons who need a reliable and easy to use constant current muscle locating surgical stimulator when carrying out the Peña, “Pull-through” or PSARP (posterior sagittal anorectoplasty) reconstruction technique in children. Now used in over 30 countries around the globe, the Digitimer DS7AP is employed by a paediatric surgeon to identify underlying musculature which is used to reconstruct the rectum and anal sphincter.  The DS7AP is the only stimulator currently cleared by the United States FDA for use in this technique and is the perfect replacement for ageing Radionics PS-1 or Integra PS-2 “Peña Stimulators”.

The DS7AP output can be operated using a front panel toggle switch or optional foot pedal (D185-FS1) and can be supplied with single-use disposable bipolar probes (DS7A-DP).

The DS7AP generates a constant current stimulus of 200µs or 500µs duration at a fixed frequency of 50Hz. Current amplitude is dial controlled over the range of 0-100mA and the stimulator has a compliance voltage of 100V.  The DS7AP Muscle Locating Stimulator is FDA cleared and a CE certified medical device.

CAUTION: Federal law restricted Muscle Locating Stimulator to sales by, or on order, of a practitioner licensed by the law of the State in which he/she practices to use or order the user of the device.

Please note that the DS7AP is no longer available for sale in Canada, as it is not registered with Health Canada as a medical device.
