Abstract
A device for detaching parietal thrombi from a blood vessel is disclosed, comprising a catheter including at least one catheter section, wherein an outer diameter of the at least one catheter section is changeable and at least one wall opening extends transversely through a wall of the at least one catheter section The catheter wall along the at least one catheter section is a resilient and deformable material. The catheter is transformed from a smaller catheter outer diameter to a larger catheter outer diameter by a resilient change in shape. A displacement body can be introduced into the at least one catheter section which is transformed in diameter to deform the catheter from the smaller catheter outer diameter to the larger outer diameter for capturing thrombus material.

A device for detaching parietal thrombi from a blood vessel, comprising a catheter including at least one catheter section including a wall, at least one opening passing transversely completely through the wall in at least one catheter section and means for changing at least an inner and outer diameter of the at least one catheter section and the wall comprising a resilient material;
- and wherein
- the diameter of the catheter is changed by the means for changing the inner and outer diameter from a smaller catheter outer diameter to a larger catheter outer diameter in the at least one catheter section, the means being introduced into the at least one catheter section and increasing the outer diameter of the at least one catheter section from a smaller diameter to a larger diameter to cause resilient deforming of at least one catheter section to assume the larger diameter to cause the at least one opening to contact and capture at least part of the parietal thrombi which adheres to the blood vessel and when the means decreases in outer diameter within the blood vessel at least part of the parietal thrombi within the at least one opening is detached from the blood vessel;
- and
- withdrawal of the catheter from the blood vessel removes the detached part of the parietal thrombi.
