Abstract:
1. A delivery catheter system comprising: a guidewire, an embolic protection filter comprising a tubular member for receiving the guidewire, and a delivery catheter, the delivery catheter comprising a catheter shaft, an engagement element and an operating element, the catheter shaft defining a proximal end, a distal end and a control lumen for the operating element; the engagement element is attached to and extends distally from the catheter shaft, the engagement element comprising a proximal end, a distal end and a distal region adjacent the distal end; a pod defining a reception space for the filter, the pod being slidable relative to the engagement element over the distal region of the engagement element upon operation of the operating element to facilitate deployment of the filter from within the reception space, the pod having a proximal end and a distal end; and the engagement element is adapted for engaging the filter in the reception space upon sliding of the pod proximally relative to the engagement element; wherein the engagement element defines a guidewire lumen therethrough for passage of the guidewire, the guidewire lumen being separate from the control lumen, the engagement element and the filter are not attached to and can move independently of the guidewire, the engagement element is slidable relative to the filter, the pod and the operating element, the guidewire is separate from the operating element, and the engagement element is adapted to slide completely within the pod, such that the distal end of the engagement element is proximal of the distal end of the pod.
