Abstract
A catheter system 1 has an internal reception space for an embolic protection filter 10 to enable the filter 10 to be transported through a vasculature 20 and a treatment means such as a stent 15 to facilitate treatment. The catheter system may, in some configurations be used for retrieval of a filter 10 and stenting of a lesion with a stent 15. The procedure may also involve post dilitation using an on-board balloon 16.
