摘要： A device capable of capturing and facilitating the removal of a thrombus in blood vessels (or stones in biliary or urinary ducts, or foreign bodies) uses a soft coil mesh with the aid of a pull wire or string to engage the surface of a thrombus, and remove the captured thrombus. The soft coil mesh 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 elements forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls. The use of multiple coil mesh elements, delivered through a single lumen or multiple lumens, preferably with separate control of at least one end of each coil, provides a firm grasp on a distal side of a thrombus, assisting in non-disruptive or minimally disrupted removal of the thrombus upon withdrawal of the device.

摘要： An intravascular thrombus retraction device and method utilizing wires compressible into a compact form within a catheter and are self-expandable into a wire mesh web with fluid-penetrable openings in the wire mesh small enough to filter clot particles. A base of the wire mesh web is connected to a radially ring-shaped structure supporting and maintaining an opening in the base of the wire mesh and forming a thrombus capture volume. The ring-shaped structure is compressible into the catheter and is self-expandable when free of compressive forces within the catheter to open up into the open, expanded ring-shaped structure, maintaining the opening in the opening in the base of the wire mesh.

摘要： This invention provides a method and a device for treating hemodynamically significant aneurysms especially in the intracranial and extracranial circulation regions using either X-ray fluoroscopy or real-time magnetic resonance (MR) imaging guidance. An MR-visible parachute-shaped occlusion device, e.g., containing multiple elongated filamentary loops made of a memory metal, elastomeric hydrogel or other expansile material, is deployed into the aneurysm by radial expansion of the expansile material outwardly into contact with the interior aneurysm surface. The device is firmly positioned against the interior aneurysm surface using a coating which adheres to that interior aneurysm surface. The device may be filled with a hardenable polymer for permanent and complete aneurysm occlusion. Wide-neck aneurysms may be treated with the same device, with the addition of a temporary balloon expanded in the parent vessel to allow expansion of the occluding device within the aneurysm, instillation of the polymer into the device, and detachment of the device from the transporting catheter. Detachment of the aneurysm occlusion device from a transport catheter is achieved by mechanical, electrical and/or chemical decoupling. A coating applied to the surface of the parachute device may induce thrombotic occlusion of the aneurysm by timed delivery of biologic modifier drugs which promote collagen formation, fibroblast growth, and endothelial ingrowth within the aneurysm. The catheter systems may have attached microcoils or may be impregnated with MR-visible agents to permit visualization in MR imaging systems.
