SynchroMed II Drug Infusion System
Targeted Drug Delivery
Targeted Drug Delivery
The Medtronic SynchroMed™ II pump is part of the SynchroMed II programmable infusion system that stores and delivers pain medication into the intrathecal space, according to instructions programmed by the clinician. The pump and catheter are implanted under the skin.
Medtronic has implemented four design changes to improve the design and performance of the pump, such as the application of diamond-like carbon coating (DLC). DLC is a highly durable, thin coating applied to SynchroMed II motor shafts to prevent wear. This change is projected to address over 99% of shaft wear, decreasing the occurrence of motor stalls.1
The SynchroMed II Pump is programmable by the Clinician Programmer, which features visuals, workflow guides, a vibrant backlit screen, and a wireless communicator to help simplify programming.
In Pumps Returned and Analyzed for Motor Stall:1
|What We've Done:1|
|Shaft wear is observed in 59%||Applied Diamond-like Carbon Coating to Shaft
Projected to address over 99% of shaft wear (Implemented in 2017)
|Corrosion of the drive gear is observed in 2%||Modified the GearWheel Material
Projected to address over 93% of corrosion of the drive gear (Implemented in 2016)
|Internal shorting is observed in 14%||Encapsulated the Feedthroughs
Projected to address over 96% of internal shorting (Implemented in 2016)
The implementation of these three design changes DOES NOT IMPLY an equivalent percent reduction in motor stall.
Data driving the four design enhancements came from:
Overall reliability of the SynchroMed II pump is 91% at 6 years.2
The drug enters the pump through the reservoir fill port and passes through the reservoir valve and into the SynchroMed II pump reservoir. At normal body temperatures, pressurized gas that is stored below the reservoir expands, exerting constant pressure on the reservoir. This pressure advances drug into the SynchroMed II pump tubing.
The peristaltic action of the SynchroMed II pump moves the drug from the pump reservoir, through the pump tubing, check valve, catheter port, and implanted catheter, to the infusion site.
The catheter access port (CAP) allows injection of the drug directly into the implanted catheter for drug administration and diagnostic purposes. Drug injected into the CAP bypasses the SynchroMed II pump mechanism and goes directly through the catheter port into the implanted catheter to the infusion site.
Implanting the SynchroMed II infusion pump under the appropriate conditions will not restrict patients from receiving a full body MRI scan. The SynchroMed II infusion system allows safe full-body access to 1.5 and 3.0-Tesla MRI.* The pump is designed to resume programmed therapy after the scan.†
