Poster presents data on 957 refill procedures. Accuracy is shown to be 97.3% ±0.4%. Data was analyzed several ways; by distribution of refill accuracy, accuracy by flow rate, and accuracy by number of months since implant. Refill accuracy is shown to be generally independent of flow rate and number of months since implant. Accuracy in measurement (human error) is discussed as potentially being responsible for accuracy being lower in certain months post-op. Measurement accuracy aside, pump is shown to have accuracy significantly greater than industry standard of ±14.5%.
