DS5 Isolated Bipolar Constant Current Stimulator

This isolated constant current biphasic nerve stimulator is controlled by an analogue voltage input which the DS5 translates into an isolated constant current stimulus (up to ±50mA), precisely replicating the shape of the input waveform.  While It has been designed for nerve excitability research, the DS5 should be of interest to anyone wishing to control skin surface stimulation protocols via software/hardware combinations capable of producing a suitable input voltage waveform e.g semi-automated pain research or sensory threshold testing.

Suitable as a general purpose nerve stimulator or muscle stimulator, the DS7Aprovides up to 100mA constant current high voltage pulses of brief duration for percutaneous stimulation during investigation of the electrical activity of nerve and muscle tissue.  The DS7A is also commonly used in pain research applications.   The output current is continuously variable over the range 0 to 100mA.

DS7A/AH & PSARP  Peripheral Stimulators

The DS7AH allows currents up to 1A with a maximum pulse duration limit of 200µs. This model is offered to overcome the difficulties of stimulating deep peripheral nerves, or large muscles such as the quadriceps with large area electrodes.  The DS7A or DS7AH can be triggered by an external device such as our new DG2A Train/Delay Generator.  For applications that require a higher output, we recommend our D185 MultiPulse 

DS7A PSARP Muscle Locating Electrical Stimulator

The Digitimer DS7A PSARP Muscle Stimulator is a variant of our MDD CE certified and FDA cleared DS7A Constant Current Stimulator (see above). Like the original Pena stimulator, our unit has been specially designed to meet the requirements of paediatric surgeons who need a reliable and easy to use muscle locating surgical stimulator when carrying out the Peña, "Pull-through" or PSARP anorectal reconstruction technique in children.

D185 Cortical Stimulator

Now used worldwide as an effective tool for intraoperative monitoring (IOM) of the spinal cord, the D185 is the ONLY standalone surgical stimulator with FDA clearance for this technique.  The D185 transcranial stimulator allows transcranial motor evoked potentials (MEPs) to be used in surgical procedures such as scoliosis correction, spinal tumour resection and thoraco-abdominal aortic aneurysm (TAAA) repair.  The 1000V power source means that MEPs can even be evoked in patients with pre-existing neuropathologies.  Recent design enhancements facilitate (external) control of the trigger settings, making it easier to interface the D185 with various EMG systems.  In addition, customer feedback has prompted the inclusion of an added polarity reversal feature.

As a Peripheral Nerve Stimulator:  Although the D185 was designed for transcranial cortical stimulation during intraoperative monitoring, the brief high voltage output also makes it suitable for use as a spinal root stimulator during differential diagnosis of peripheral nerve disorders such as multifocal motor neuropathy and motor neuron disease.  The high voltage allows you to effectively stimulate deep nerve roots as they exit the spinal column, while the very short pulse duration minimizes patient discomfort.
