Objectives  The ISPR was initially created to monitor the product performance of Medtronic implanted intrathecal drug infusion and spinal cord systems available in the United States.    Materials and Methods  Data were collected from 50 representative sites implanting and following patients with intrathecal drug delivery systems across the United States between August 7, 2003 and January 31, 2014. Device performance over time was estimated using life table survival methods.    Results  Of the 6093 patients enrolled in the ISPR, 3405 (55.9%) were female and 2675 (43.9%) were male, and 13 (0.2%) did not provide gender data. The average age at enrollment was 52.9 years (SD =17.6 years) and average follow‐up time was 29.6 months. Currently, the estimates of device survival from pump‐related events exceed 90% for all pump models across the applicable follow‐up time points. The majority of product performance events were catheter‐related. At 5 years of follow‐up, all applicable catheter models, with the exception of revised not as designed or grafted not as designed catheters, had greater than 81% survival from catheter‐related events.    Conclusions  The ISPR is designed to serve as an ongoing source of system and device‐related information with a focus on “real‐world” safety and product performance. ISPR data continue to be used to guide future product development efforts aimed at improving product reliability and quality.
