An embolic protection system comprises an embolic protection filter 1 having a collapsed delivery configuration and an expanded deployed configuration. The filter 1 is housed in the collapsed configuration in a reception space of a delivery catheter 20. The delivery catheter 20 containing the filter 1 is housed in a sealed sterile pouch 35. The filter 1 may be coated with a non-thrombogenic coating and an adhesion preventer 9 such as a silicon gel is used to substantially prevent adhesion of adjacent folds of the filter 1 when the filter is in the collapsed configuration in the delivery catheter 20.
