Desired improvements in IT Drug Delivery?
• Reliable pumping mechanism.• Long battery life.• Troubleshooting tools.• Enhanced safety features. • Simple programming.• Dependable catheter.
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.
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.
4
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.
5
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.
6
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
7
Benefits• 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 RefillsPrevent pump pocket refill errors.
8
Easy and Fast.
Benefits• Simple and flexible dosing
options. • Icon-driven user interface.• Backlit full-color screen.• Simple roller wheel control.
10
Benefits• Improves refill procedure
efficiency and patient comfort.
• Rechargeable CU battery– Never uses the pump battery for
communication extending pump battery life.
