Open the CIPO recordAbstract From the Canadian patent
A device captures and assists in the removal of a thrombus in arteries even , in small arteries. The device uses a soft coil mesh to engage the surface of a thrombus, and a guidewire is used to retract the soft coil mesh with the captured thrombus. The soft coil is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical element forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls.
