Abstract
The present invention relates to a vascular filter which can be placed inside a body cavity, such as a blood vessel. A catheter may be used to deliver the filter, and consists of a tubular basic body with a distal end, a proximal end and a lumen extending between the ends. The vascular filter may be received in a compressed state inside the catheter lumen. The catheter may include an ejection device, which can be used to eject the vascular filter from the distal end of the catheter. Some portion of the vascular filter may tend to push off in a resilient manner against the distal end of the catheter, and the filter preferably includes a brake for acting on the catheter lumen, which tends to slow and control ejection from the catheter.
