2. Desired improvements in IT Drug Delivery?
Reliable pumping mechanism.
Long battery life.
Troubleshooting tools.
Enhanced safety features.
Simple programming.
Dependable catheter.

3. MedStream™ Programmable Pump
The system consists of:
Implantable Pump
20mL and 40mL reservoirs
Intrathecal Catheter(s)
SureStream™ Intraspinal
Codman® Silicone Intraspinal
Control Unit
Indicated for:
Intrathecal delivery of baclofen for severe spasticity.

4. Benefits Simple & durable design.
Only one moving part.
> 6 million cycles without failure; equivalent to 78 years of service.
Accurate dosage within 10% across the entire flow range.

5. Benefits Fewer revision surgeries.
Higher infusion rates can be used without effecting battery life.
Typical peristaltic pump lasts only 5-7 years depending on flow rate.

6. Benefits Easily verify drug remaining in pump without emptying it.
Confirm that drug has entered reservoir and not pump pocket.
Useful diagnostic tool when troubleshooting system.

7. Benefits Patients can safely undergo MRI procedures.
No binding of gears / rotors.
No need to stop flow or empty pump before MRI.
Confirm pump status after MRI

8. Benefits Safe Pump Refills Raised refill port makes locating easy.
Positive pressure provides tactile assurance that you are in the port.
Drug Volume Gauge verifies that refill of pump has occurred.
Safe Pump Refills
Prevent pump pocket refill errors.

9. Easy and Fast.

10. Benefits Simple and flexible dosing options.
Icon-driven user interface.
Backlit full-color screen.
Simple roller wheel control.

11. Benefits Improves refill procedure efficiency and patient comfort.
Rechargeable CU battery
Never uses the pump battery for communication extending pump battery life.

12. SureStream™ kink resistant catheter.
The titanium coil design ensures flow of medication without occlusion.
Silicone
SURESTREAM
Kinking
No Kinking
Look Inside

13. Future Technology Needed
Dual chamber pump.
Catheter flow sensor.
Therapy data trending.
More drug options.
